1. SUS416 Stainless Steel Overview
SUS416 is a martensitic stainless steel, commonly known as stainless iron, that boasts impressive corrosion resistance. Its domestic grade is Y1Cr13, recognized as the best machinable stainless steel. This grade features a high chromium content along with sulfur, enhancing its cutting capabilities.
Commonly utilized in the manufacturing of various mechanical components such as bolts, nuts, and bearings, SUS416 excels in machining due to its favorable workability. Its primary advantage lies in its ability to achieve high hardness after heat treatment, a trait not found in the 300 series stainless steels. However, it does face a slight disadvantage in corrosion resistance compared to other stainless types like 304, though it passes neutral salt spray tests after passivation.
