ASTM A588 grade A for weather resistant steel, 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.

For Q345B steel plate, Q stands for the yield of Q345B material. The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. It ASTM A588 grade A for weather resistant steel is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.

Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. ASTM A588 grade A for weather resistant steel, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.
