Stainless Steel CA15 (SS410)

SS410 is a Martensitic stainless steel with corrosion resistant property. The casting grade is named as CA15 (J91150) in standard of /A743M and /A217M and ASTM A487/A487M only. It’s a cheap stainless steel with good hardness.

Casting Quality Industrial provide CA-15 (SS410) by sand casting or investment casting (lost wax precision casting) process.

EN 10283 Grade GX12Cr12, EN Number 1.4011
EN 10088 Grade X12Cr13, number EN1.4006;




CA-15 (SS410) is mainly used in fluid industry, such as bearings, bushings, chemical and food processing equipment, conveyor rollers, cutlery, impellers, medical devices, pump and valve components, turbine engine parts



Involving high temperature are used in the removal of discontinuities, CA-15(SS410) need a preheated at 400°F [205°C]. And the Martensitic stainless steel shall to be re-tempered after welding repairing.

CA15 (SS410) Heat treatment process: WWW.CASTINGQUALITY.COM

(1) Heat to 1750°F [955°C] minimum, air cool and temper at 1100°F [595°C] minimum, or

(2) Anneal at 1450°F [790°C] minimum. WWW.CASTINGQUALITY.COM


In standard of ASTM A487, Austenitizing temperature at 1750°F [955°C], quenching cool at 400°F [205°C] in air or liquid, but need for TEMPRING TEMPERATURE to get good property. Double temper with the final temper at a lower temperature than the intermediate temper, air cool to below 200°F [95°C] after first temper.:

CA15 CLASS A: Tempering temperature at 900°F [480°C]

CA15 CLASS B: Tempering temperature at 1100°F [595°C]

CA15 CLASS C: Tempering temperature at 1150°F [620°C]

CA15 CLASS D: Tempering temperature at 1150°F [260°C]
