AISI SAE 8620 steel is a commonly used low-alloy material for carburizing, with excellent carburizing response, good hardenability for most section sizes, it has many extensive applications due to its low cost, better machinability, and availability.

AISI 8620 Steel is a low alloy nickel, chromium, molybdenum case hardening steel, generally supplied in the as rolled condition with a maximum hardness HB 255max. SAE steel 8620 offers high external strength and good internal strength, making it highly wear resistant. AISI 8620 steel has a higher core strength than grades 8615 and 8617.

AISI 8620 alloy steel is a common, carburizing alloy steel. This alloy steel is flexible during hardening treatments, thus enabling improvement of case/core properties. The following datasheet will provide more details about AISI 8620 alloy steel. The following table shows the chemical composition of AISI 8620 alloy steel.

SAE8620 是美国标准规定的一种合金结构钢的牌号，相当于我国的 20CrNiMo （ 执行标准： GB/T 3077-2015），是广泛用于 渗碳 和 碳氮共渗 的Cr-N i-Mo系表面硬化钢。 SAE8620与SAE8620H两者的区别在于有没有保证 淬透性，带H表示保证淬透性。 化学成份. 力学性能. 用途. 8620H常用于制造中小型汽车、拖拉机的发动机和传动系统中的齿轮；亦可代替12CrNi3钢制造要求心部性能较高的渗碳件、氰化件，如石油钻探和冶金露天矿用的牙轮钻头的牙爪和牙轮体。 …
