| 型号420-“刃具级”马氏体钢，类似布氏高铬钢这种*早的不锈钢。也用于外科手术刀具，可以做的非常光亮。型号430-铁素体不锈钢，装饰用，例如用于汽车饰品。良好的成型性，但耐温性和抗腐蚀性要差。型号440-高强度刃具钢，含碳稍高，经过适当的热处理后可以获得较高屈服强度， Model 420 - "cutting tool grade" martensitic steel, similar to Brinell high chromium steel, an early stainless steel. It is also used for surgical tools, which can be made very bright. Model 430 ferritic stainless steel for decoration, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance. Model 440 high strength cutting tool steel with slightly higher carbon content can obtain higher yield strength after appropriate heat treatment, 硬度可以达到58HRC，属于*硬的不锈钢之列。常见的应用例子就是“剃须刀片”。常用型号有三种：440A、440B、440C，另外还有440F（易加工型）。500 系列-耐热铬合金钢。600 系列-马氏体沉淀硬化不锈钢。型号630常用的沉淀硬化不锈钢型号，通常也叫17-4；17%Cr，4%Ni。，铬18-20。 The hardness can reach 58hrc, which belongs to * hard stainless steel. A common application example is "razor blade". There are three common models: 440A, 440b, 440C, and 440f (easy to process). 500 series - heat resistant chromium alloy steel. 600 series - Martensitic precipitation hardening stainless steel. Model 630 is a commonly used precipitation hardening stainless steel model, usually also known as 17-4; 17%Cr，4%Ni。， Chromium 18-20. |
