Development and Production of HSLA Wear-Resistant Steel
In this paper, the development and production of Ti-Cr-B microalloyed NM400 wear-resistant steel were discussed, along with the influence of heat treatment process parameters on the mechanical properties. The continuous cooling transformation behavior of steel was investigated by means of thermal simulator. Effects of austenitizing temperature on microstructures and properties of steel were studied. Martensite laths evolution, carbide transformation and precipitation behavior were observed by TEM. The wear-resistance of steel was compared with other similar steels. The results show that the steel has high strength and hardness, great low-temperature toughness and wear-resistance. The tensile strength is more than 1300 MPa, and the hardness is in the range of 390 ～430 HB. Due to the good hardenability,the steel has a uniform hardness distribution on the surface and thickness direction. The plate shape, cold bending property and weldability of the product can meet the user’s requirement.
