SAE 8620 Alloy Steel

Generally, Sae 8620 Alloy Steels Are Supplied As-Rolled With A Maximum Hardness of Hb 255max With Nickel, Chromium, and Molybdenum Low Alloy Case Hardening Steel—high Internal Strength And Good External Strength Make Sae 8620 Alloy Steel Highly Wear-Resistant. Compared to grades 8615 and 8617, SAE 8620 steel has a stronger core strength. It Is Also Flexible During Hardening Treatments, Having Improved Case/Core Properties As A Result. A Prehardened And Tempered 8620 Nitriding Due Can Further Harden Steel To Its Low Carbon Content, But Will Not Respond Satisfactorily To Flame Or Induction Hardening Methods.
