HB 450 wear-resistant steel plates are composed of low-alloyed steel containing 0.26–0.40% carbon, with major alloying elements including manganese (≤1.60%), silicon (≤0.60%), chromium (≤1.40%), nickel (≤1.50%), and molybdenum (≤0.60%). These elements significantly enhance hardness, strength, and wear resistance. The plates exhibit Brinell hardness between 425–475 HBW, a yield strength of approximately 1240 MPa, and an elongation of around 10%. This unique balance of hardness, toughness, and ductility ensures excellent performance under severe wear, abrasion, and impact conditions, making HB 450 plates ideal for heavy-duty and high-stress industrial environments.
HB 450 wear-resistant steel plates are made of a low-alloyed steel with a content of carbon in the range of 0.26% to 0.40%. Major alloying elements are manganese (up to 1.60%), silicon (up to 0.60%), chromium (up to 1.40%), nickel (up to 1.50%), and molybdenum (up to 0.60%). The above elements increase the hardness and wear resistance of the steel. Mechanical properties are a Brinell hardness of 425–475 HBW, yield strength of about 1240 MPa, and elongation of about 10%. Such properties render HB 450 plates ideal for high-impact and abrasion environments.

HB 450 wear-resistant steel plates are widely used in industries where materials are exposed to high wear, impact, and abrasive forces. In the mining sector, they serve in crusher liners, chutes, and hoppers. The construction industry utilizes them for dump truck bodies, excavator buckets, and earthmoving equipment. They are also critical in the manufacture of heavy-duty machinery, such as bulldozer blades, conveyor systems, and loading equipment. With superior hardness, toughness, and durability, HB 450 plates minimize maintenance needs and enhance operational efficiency, ensuring reliable performance and extended service life in the harshest industrial environments.
