Abstract (en)

A wear-resistant steel for the intermediate and room temperature service consisting essentially of: carbon : from 0.08 to 0.40 wt.%, silicon : from 0.8 to 2.5 wt.%, manganese : from 0.1 to 2.0 wt.%, and the balance being iron and incidental impurities. The above-mentioned wear-resistant steel has a Brinell hardness at a room-temperature of at least 250, a Brinell hardness at a temperature of 300 DEG C of at least 90% of its room-temperature Brinell hardness and a Brinell hardness at a temperature of 400 DEG C of at least 70% of its room-temperature Brinell hardness.
