Cold rolling refers to a rolling process that uses the pressure of rolls to squeeze steel to change the shape of the steel at room temperature. The advantafe of cold rolling is fast forming speed, high output, the coating is not damaged, and it can be made into a variety of cross-sectional forms to meet the needs of the use conditions. In addition, cold rolling can cause large plastic deformation of the steel, thereby increasing the yield point of the steel. Which is Widely used in home appliances and other industries.
What Is The Difference Between 304, 304L And 304H?
Answer:
304 is considered the most versatile and widely used austenitic stainless steel, 304L is the ultra low carbon variant of 304 stainless, while 304H is the high carbon version of the 304 stainless. Carbon content is the only chemical difference between these three grades, leading 304L to perform better in corrosive environments and be easier to weld.
Why Is 304L Easier To Weld Than 304?
Answer:
The lower carbon content in 304L helps to remove the chromium carbide precipitation that occurs during the welding, putting 304L at lower risk for intergranular corrosion even in highly corrosive environments.
What Is The Yield Strength Of This Grade Stainless Steel?
Answer:
The yield strength for 304 stainless is 205 MPa (30 ksi).
