What is the asme material JIS corten steel grade SMA400BP equivalent

Chromium element (Cr element) can improve the strength and hardness of JIS corten steel grade SMA400BP, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

Q355GNH weather-resistant steel, that is, atmospheric corrosion-resistant steel, is a low alloy steel series between ordinary steel and stainless steel. JIS corten steel grade SMA400BP, Q355GNH alloy steel plate and sheet are mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time. It is used to manufacture containers, railway vehicles, oil derricks, seaport buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.

We focus on ensuring that we have a large availability of all hot rolled plate thicknesses and dimensions so that all normal requirements can be met on an ex-stock basis. We also aim to be able to meet requirements for larger quantities that would normally be ordered from the mill in order to help customers in the oil and gas industries to accelerate deliveries times of their projects.
