EN 10155 equivalent materials with corrosion resistance

Chromium element (Cr element) can improve the strength and hardness of EN 10155 equivalent materials, 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.

AR400 wear resistant steel is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance of the steel, EN 10155 equivalent materials. The average hardness of AR400 wear-resistant special structural steel is 400HB. After quenching, AR400 wear resistant steel has good martensite bainite microstructure. The addition of Molybdenum (Mo), Nickel (Ni) and Boron (B) alloys ensures uniform texture in the whole thickness direction of AR400 wear resistant steel.
