304L stainless steel Chinese supplier

304L stainless steel is an extra low-carbon variation of 304 stainless steel with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. As a result, this alloy can be used in the “as-welded” condition, even in severe corrosive conditions, it often eliminates the necessity of annealing weldments except for applications specifying stress relief, it has slightly lower mechanical properties than 304 stainless steel.

304L stainless steel corrosion resistance :

These steels exhibit excellent resistance to a wide range of atmospheric, chemical, textile, petroleum and food industryexposures.

Types 304 and 304L have very good drawability. Their combination of low yield strength and high elongation permits successful forming of complex shapes. However, these grades work harden rapidly. To relieve stresses produced in severe forming or spinning,parts should be full annealed or stressrelief annealed as soon as possible after forming.
