The main advantage of precipitation hardening steels in general is that they can be supplied to a manufacturer in an condition of optimal machinability and then the only heat treatment required is an extended very low temperature soak.

沉淀硬化的主要优势在于钢材厂商在将钢材提供给刀具制作厂商的时候可以让H-1保持最好的打磨性，降低刀具制作厂商的加工难度，而刀具制作厂商在完成打磨之后需要做的唯一的热处理就是将H-1进行深冷浸泡以提高强度。

Precipitation hardening stainless steels may be martensitic, semi-austenitic or austenitic.

沉淀硬化不锈钢可马氏体，半奥氏体或奥氏体。
