【Abstract】 Mn-B bainitic steels are alloyed with common element Mn and trace element B, so that they are cheaper compared with Mo- B bainitic steels. The series of materials can be hardened through air-cooling, which leads to good combination of strength and toughness. They have been used in many enterprises. The products with maturated producing skill can be direct yielded in steel plants. Various kinds of products are excellent in properties with low production cost, and can bring about high profits, so that they exhibit strong competitive capability in markets. Especially in recent years, obvious progresses in fine structures, strength and toughness have been made and already being used in bianitic wear resistant steels.更多还原
