1. Brief Introduction for 1.4021&1.4028
Stainless Steel 1.4021 is a martensitic machinning bar with machinability improved with the addition of Sulphur. The Sulphur also lowers weldability, corrosion resistance, and formability to below that of its non-free machining equivalent Grade 410.
Martensitic stainless steels are designed for high hardness, and other properties are compromised to an extent. Their functional operating temperature range is restricted by their loss of ductility at sub-zero temperatures, and loss of strength by over-tempering at high temperatures.
Alloy designations of 1.4021 is similar, but it may not be a direct equivalent to: 420, UNS42000, 1.4021, 1.4024, 1.4028, 1.4029, 1.4030, and 1.4034. It is supplied in the form of a bar.
