nm400 equivalent material may maintain high volatility in price

ASTM A242, NM400 equivalent material used in marine and humid environments, is a high-strength, corrosion-resistant alloy with a yield strength of 42,000 to 50,000 psi and an allowable bending stress of 25,200 to 30,000 psi.

Our company's NM400 equivalent material power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the NM400 equivalent material utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest NM400 equivalent material processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain NM400 equivalent material by rolling method.

Chromium molybdenum steel, also known as medium temperature hydrogen resistant steel, refers to the steel added with Cr (≤ 10%), Mo and other alloy elements to significantly improve the high-temperature strength limit and creep limit, and has good hydrogen corrosion resistance and high-temperature resistance performance. NM400 equivalent material, Chromium molybdenum steel is widely used in oil refining, chemical and other hydrogen containing devices and high-temperature equipment, and is one of the commonly used steels for pressure vessels.
