S420ML steel tube, Manganese steel plate is a low alloy high strength steel plate with good weldability. Manganese steel plate is the main material of general pressure vessel. Manganese steel plate is mainly used to make engineering structural parts, roof beam of workshop and tower crane tower body. Manganese steel plate has high rupture strength and creep strength at high temperature and good impact toughness at low temperature. High strength steel is a kind of wear-resistant steel for heavy industry. Its application fields include quarrying, mining, mining, coal industry, casting and steel industry, etc.

Q245R boiler steel plate introduction: Q is the first letter of "Qu" Chinese Pinyin; Number 245 is the yield strength value; R: is the first character of "Rong" Chinese Pinyin. Q245R steel is a special plate for pressure vessels and boilers with a yield strength of 245MPa. It has outstanding mechanical properties and processability. If you have special requirements, our company can supply Z15, Z25, Z35 and other Z performance tests.
