EN S355ML steel plates has good weldability

EN S355ML steel plates, NM400 wear plate is a special structural steel with high wear resistance. Generally speaking, the higher the hardness, the higher the wear resistance. The average hardness of NM400 wear plate is 400HB. After quenching, or quenching and quenching, NM400 wear plate has a good martensite-bainite microstructure. The addition of molybdenum, nickel, and boron alloys ensures uniform texture throughout the thickness direction.

It has good toughness. By strictly controlling the chemical composition, reducing the content of EN S355ML steel plates harmful elements and selecting reasonable heat treatment conditions, NM360 steel plate has good toughness. Therefore, the highly reliable structural parts can be constructed according to the brittle failure of wear-resistant components. Uniform and beautiful quality, EN S355ML steel plates using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.
