What is A537 class 3 pressure vessel steel sheet price per ton

Boiler steel plate A537 class 3 pressure vessel steel sheet mainly refers to the hot-rolled medium and heavy plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The main boiler steel materials are high-quality structural steel and low-alloy heat-resistant steel. Common boiler steel includes low-carbon killed steel A537 class 3 pressure vessel steel sheet smelted in open furnace or low-carbon steel smelted in electric furnace, with carbon content WC in the range of 0.16% - 0.26%.

The main metal material A537 class 3 pressure vessel steel sheet used to make the boiler is steel. The main boiler body is composed of the parts which bear static load under normal temperature and the parts which bear high pressure and high temperature. The former part can be made of general structural steel, while the latter part must be made of steel with special properties, i.e. boiler steel. Boiler steel is required to have good high temperature resistance, stable structure, machining performance, etc. properties.
