Introduction to 301, 304, 310S, 321 316
301
Austenitic steel with Ni and Cr lower than 304. The tensile strengthen and hardness will be higher by cold rolled processing, at the same time, it will be magnetic.
Application: Used for elastic element, structure opponents, conveyor belt, and mechanical spring
