SUS304 is the typical steel grades of austenitic stainless steel, as the most used in the forming of stainless steel sheets, is well known as ferritic stainless steel grade SUS430.This grade has very good manufacturing formality, is widely used in durable consuming goods, structure materials and some other aspects. In addition,it has low temperature flexibility, is widely used for refrigeration equipment or hydraulic gas container and pressure vessels.
