It is an austenitic, corrosion resistant steel with excellent power, toughness, fabrication characteristics and weldability. The low carbon version, 304L, may be required for full corrosion resistance when thicker sections are welded. The 304H version has a assured minimum carbon content material, which ensures good power at high temperatures. This type of chrome steel plate has become extremely popular in the chemical, medical and pharmaceutical business due to its robust resistance to corrosion. 316 and 316L stainless-steel plate has a better chromium content and molybdenum which makes this sort of chrome steel plate immune to corrosive components. Because of its composition, 316 and 316L stainless-steel plate is extra tolerant of corrosion than its 304 and 304L chrome steel plate counterpart.
