Cast Stainless Steel to ASTM Specifications
Anaya Enterprises pours corrosion-resistant stainless steel castings to ASTM A351, A743 and A744, martensitic grades to A487 and A217, precipitation-hardening grades to A747 and duplex grades to A890 and A995. Every grade on this page is cast to the ASTM specification shown, with the minimum mechanical properties listed in the grade tables.
We cast by sand mould or no-bake moulding, and cylindrical parts such as sleeves, bushes and liners can be centrifugally cast in high alloy steel. Our custom manufacturing team machines castings to your drawings, so you can order a finished component rather than a raw casting.
Which ASTM Specification Fits Your Part
Many cast stainless grades appear in more than one specification. The specification sets the testing and quality requirements, so choose it by the duty of the part:
- A743: corrosion-resistant iron-chromium and iron-chromium-nickel castings for general application.
- A744: the same alloy family for severe corrosive service, with added requirements.
- A351: austenitic and duplex castings for valves, flanges, fittings and other pressure-containing parts.
- A487 and A217: steel castings for pressure service, including the martensitic grades CA-15 and CA-6NM.
- A747: precipitation-hardening stainless castings, CB7Cu-1 and CB7Cu-2.
- A890 and A995: duplex castings for general application (A890) and for pressure-containing parts (A995).
If your drawing names a wrought grade such as 316, the Similar Wrought Alloy column in the grade table gives its cast equivalent. Not sure? Send the drawing and ask our engineers.
Common Cast Stainless Grades
- CF8 and CF3: cast 304 and 304L. The low-carbon “3” grades, at 0.03% carbon maximum, are the usual choice when a casting will be welded.
- CF8M and CF3M: cast 316 and 316L. Molybdenum improves resistance to pitting and crevice corrosion in chloride service.
- CF8C: cast 347, stabilised with niobium against intergranular corrosion.
- CA-15 and CA-6NM: martensitic chromium grades, cast 410 and its nickel-molybdenum variant, combining strength and hardness with moderate corrosion resistance.
- CN-7M: the cast form of Alloy 20, developed for sulphuric acid service.
- CK-3MCuN: a 6% molybdenum super-austenitic grade for seawater and other severe chloride service.
- CB7Cu-1 and CB7Cu-2: precipitation-hardening grades, cast 17-4 PH and 15-5 PH, heat treated to conditions from H900 to H1150 to balance strength against toughness.
Where Stainless Castings Are Used
Cast stainless is specified wherever corrosion, hygiene or temperature rules out carbon steel or iron, as in pumps, valves, food processing, marine and chemical service. See how we support pumps, food processing, marine, oil & gas and power generation.
