Cast Metals Federation (CMF)

The CMF provides an impartial, free link to all the best in cast metals production. With 200 members producing in total over £1.8bn of castings in any size, any shape, any metal, any weight and any process, the CMF brings you directly into contact with foundries and foundry supply companies for every application.

Chemical compositions of stainless steels to BS 3146-2

BS 3146-2 is the material standard for stainless steel and some nickel based alloy castings, to be made by the investment (or lost wax) process. Martensitic, precipitation hardening, austenitic austenitic-ferritic (duplex) grades are included. The chemical composition of the stainless steel and some nickel based alloys in the standard are listed.

Chemical compositions of ACI stainless and heat resisting steel castings grades

ASTM standards A297, A351, A743, A744 and A890 specify castings for corrosion and heat-resisting service. The grade designations used in these standards are those originally developed by the ACI, the Alloy Casting Institute. (Now the Steel Founder's Society of America). These standards include the 'C' grades for aqueous (wet) corrosion service at temperatures up to 650 C and the 'H' grades for high temperature service at temperatures generally over 600 C. The range of steels listed in this article includes martensitic, ferritic, precipitation hardening, austenitic and austenitic-ferritic (duplex) steel grades and some nickel based alloys. Where appropriate, the nearest or related wrought grade is shown in the table.

Chemical composition of stainless steel castings to BS EN 10283

BS EN 10283 is the material standard for stainless steel castings for corrosion resisting purposes. Martensitic, precipitation hardening, austenitic and austenitic-ferritic (duplex) grades are included. The chemical composition of all the grades of stainless steel covered in the standard are listed.
