Trushape pours more than 50 cast alloys in eight families, from stainless and duplex steels to nickel, cobalt, copper and aluminium alloys, to ASTM, EN and customer standards, with the chemistry of every heat checked by spectrometer, for buyers across North America and Europe.
Casting material grades are standardised alloys, each defined by a chemistry range and minimum mechanical properties in a standard such as ASTM A351 or EN 10283. The right grade balances corrosion resistance, strength, temperature capability and cost for the service the part will see, and the cast grade usually has a close wrought equivalent, such as CF8M for 316.
Trushape Precision Castings is an ISO 9001, ISO 14001, ISO 45001 and ISO 13485 certified foundry in Bhavnagar, Gujarat, India. We pour more than 50 grades in eight families, from CF8M and duplex stainless steels to Inconel, Stellite, nickel aluminium bronze and A356 aluminium, check the chemistry of every heat, heat-treat in-house and ship castings with EN 10204 3.1 certificates to buyers across the United States, Canada, Mexico, the United Kingdom and the European Union.
Search a grade or its equivalent, filter by what your part needs, and pick a tile to see its standard, equivalents, chemistry limits and minimum properties. 58 grades in eight families, cast to ASTM, EN, DIN or your own specification.
ASTM A351, A743, A744. The cast form of 316.
The workhorse for pump casings, valve bodies and marine hardware.
Equivalents are the closest common matches, shown for comparison. Chemistry limits and minimum properties are those of the governing ASTM standard; for grades without them here, we cast to the standard or specification on your drawing.
Follow one heat of CF8M stainless steel from the furnace to its test certificate. Each step is recorded against the heat number, so the metal in your part traces back to its chemistry and test results.
Clean returns and alloy additions are weighed to the target chemistry and melted in an induction furnace, then brought to pouring temperature, 1,400 to 1,700°C (2,550 to 3,090°F) for steels, and deoxidised.
The heat is poured into the moulds, and a chemistry sample and test bars are cast from the same metal, so every result traces back to the parts it describes.
The sample is ground flat and sparked on a Spectromaxx or Bruker optical emission spectrometer, which reads 17 elements and compares each with the minimum and maximum limits of the grade.
Castings are heat-treated in-house to the grade and condition you specify. For CF8M that means solution annealing above 1,040°C (1,900°F) and a water quench, recorded for the certificate.
A test bar from the same heat is pulled to fracture to prove tensile strength, yield and elongation against the minimums of the standard, with hardness and impact tests where your order calls for them.
Chemistry, mechanical results, heat treatment and heat number come together on one certificate that ships with the castings. A 3.2 certificate with independent inspection is available when your order calls for it.
Each point is a grade, placed by its typical pitting resistance (PREN) and its minimum yield strength, with one lane per family. Drag to turn the map, pick a family to bring it forward, or pick a point to read it.
Above the PREN 40 rule of thumb for seawater.
PREN = %Cr + 3.3 × %Mo + 16 × %N, from typical chemistry. Yield strengths are ASTM minimums; CB7Cu-1 (17-4PH) is shown in the H900 condition.

No single alloy fits every part. A seawater pump, a white-hot furnace part and a loaded gear each need a different metal. So we pour more than fifty grades, check the chemistry of every heat and trace it from the spectrometer to the shipped part.
Most steels run across several processes, while nickel, cobalt and medical grades are investment cast. Pick a process to raise its column in 3D and drag to turn the chart.
A ceramic shell built around a wax or printed pattern gives the finest detail and accuracy in almost any alloy, including nickel, cobalt and medical grades.
Resin sand shells formed on heated metal patterns give accurate, repeatable castings at medium to high volumes.
Chemically bonded sand moulds suit larger, lower-volume castings, with no pattern heating and wide alloy choice.
A foam pattern in unbonded sand makes complex, heavier castings without cores or parting lines.
Metal dies filled by gravity make dense, repeatable non-ferrous parts with a fine surface.
3D-printed patterns and investment casting give metal parts in weeks, in the same alloys as investment casting and with no hard tooling.

Made to specThe right casting route for each alloy and size, plus heat treatment, CNC machining and testing in one facility.
IntegratedThe grades on modern drawings grew out of a century of metallurgy, from the first stainless steels to the superalloys of the jet age.
Elwood Haynes patents his cobalt-chromium alloys, the start of the Stellite family still used for valve seats and wear parts.
Krupp patents austenitic chromium-nickel steel in Germany, and Harry Brearley makes a martensitic stainless steel in Sheffield.
The first duplex stainless steels are made in Sweden, and a cast cobalt-chromium-molybdenum alloy enters dentistry and, later, implants.
Nickel-chromium alloys developed for the first jet engines open the way to today's heat-resistant superalloys.
Nitrogen-alloyed duplex grades such as 2205 arrive, followed by super duplex, bringing strength and seawater resistance together.
Trushape pours more than 50 of these grades, checks the chemistry of every heat and certifies each shipment to EN 10204 3.1.
More than 50 grades in eight families: stainless steels (austenitic, martensitic, duplex and precipitation-hardening), carbon and low-alloy steels, nickel alloys, cobalt alloys, copper alloys, aluminium and zinc alloys, tool steels, and specialty and medical grades. We cast to ASTM, EN, DIN or customer specifications and check the chemistry of every heat.
CF8M is the cast counterpart of wrought 316, covered by ASTM A351, A743 and A744. The chemistry is similar, with 18 to 21% chromium, 9 to 12% nickel and 2 to 3% molybdenum, but CF8M allows more silicon and forms a little ferrite in its austenite, which helps castability and resistance to hot cracking. It has a minimum tensile strength of 485 MPa (70 ksi), and its EN equivalent is 1.4408.
CF8 corresponds to EN 1.4308 (GX5CrNi19-10), CF8M to 1.4408 (GX5CrNiMo19-11-2) and CF3M to 1.4409 (GX2CrNiMo19-11-2), with UNS numbers J92600, J92900 and J92800. Equivalents are the closest matches rather than identical specifications, so we check chemistry, properties and testing against the standard on your drawing.
Duplex CD3MN is ASTM A890 and A995 grade 4A (EN 1.4470), the cast form of 2205, and super duplex CE3MN is grade 5A (EN 1.4469), the cast form of 2507. Their mixed austenite and ferrite structure gives a minimum yield strength of 415 and 515 MPa, at least twice that of CF8M, with strong resistance to chloride pitting and stress corrosion cracking.
PREN, the pitting resistance equivalent number, equals %Cr + 3.3 × %Mo + 16 × %N, and the higher it is, the better a stainless steel resists pitting in chlorides. Typical values are about 25 for CF8M and CF3M, 35 for duplex CD3MN and 42 for super duplex CE3MN, and a PREN of 40 or more is the common rule of thumb for seawater. Nickel alloys go further, about 51 for CW6MC (625 type) and 68 for CW12MW (C-276 type).
Yes, as CB7Cu-1 to ASTM A747 (EN 1.4525), the cast form of 17-4PH. We solution treat and age it in-house to the condition you specify, from H900 for the highest strength, with a minimum tensile strength of 1,170 MPa (170 ksi), to H1150 for more toughness, and report the results on the certificate.
Pressure-containing WCB to ASTM A216 (EN 1.0619, GP240GH), and engineering steels including C45, EN8, EN24, EN36, 4130, 4140, 4340, 8620, 42CrMo4, 16MnCr5 and 34CrNiMo6, as well as ASTM A48 gray iron. We heat-treat them in-house, normalising, quenching and tempering to reach the strength and hardness on your drawing.
Nickel alloys include Inconel 625, 713C and 718, Hastelloy C-22, C-276 and X, Monel 400 and Ni-Resist (ASTM A494 grades such as CW6MC, CX2MW, CW12MW and M35-1). Cobalt alloys include Stellite 6, 12 and 21 and ASTM F75 cobalt-chromium-molybdenum. Copper alloys include nickel aluminium bronze C95800, gunmetal C83600, phosphor bronze and high-conductivity copper. Most are investment cast.
Investment casting and rapid manufacturing handle all eight families. Shell molding suits stainless, carbon, low-alloy and tool steels and copper alloys; no-bake sand also takes aluminium; lost foam covers stainless, carbon and low-alloy steels, copper and aluminium; and gravity die casting is for copper and aluminium alloys. We recommend the route for your alloy, size and volume.
Every heat is analysed on Spectromaxx and Bruker optical emission spectrometers, which read 17 elements, and compared with the minimum and maximum limits of its grade. The results are recorded against the heat number and appear, with the mechanical tests and heat treatment, on an EN 10204 3.1 certificate; 3.2 certificates with independent inspection are available on request.
Yes. In-house melting and metallurgy let us cast to company specifications and develop custom compositions, from stainless steels with higher pitting resistance to bespoke nickel grades, qualified with you through test bars, chemistry and mechanical results.
Yes. Trushape exports castings to Germany, the UK, Belgium, Denmark, Spain and Italy and serves buyers across North America and Europe, including the United States, Canada and Mexico. Parts ship by sea or air freight with English certificates and reports, and delivery terms are agreed per order.
Whatever the part, there is an alloy that fits it. Trushape pours more than fifty grades across eight families, checks the chemistry of every heat and documents it from melt to certificate, for engineers and buyers across North America and Europe.
