: : Carbon Steel Alloy 401 - Chrome Silicon

Carbon Steel Alloy 401 Composition

C 0.51 - 0.59%, Cr 0.60 - 0.80%, Si 1.20 - 1.60%

Carbon Steel Alloy 401 Description

This material is designed for springs that must withstand considerable shock and extreme heat. Chrome silicon can be used at temperatures up to 50°F higher than chrome vanadium. Recommendations for heat treatment: Immediately after coiling, the springs should be stress relieved at about 400°C (750°F) for 30 minutes. After shot peening, the springs should be stress relieved at about 250°C (480°F) for 30 minutes. Wire is available in size ranges from 0.018" - 0.625". Commercial quality Chrome Silicon conforms to ASTM-A-401

Carbon Steel Alloy 401 Applications

Design Engineers use Chrome Silicon for shock loads and moderately elevated temperatures. Cold drawn and heat treated before fabrication.
