Welcome to BBN High Strength Steels Factory
NM500A is the wear-resistant steel grade of BBN STEEL Plant, with a thickness between 8mm and 150mm. NM500A wear-resistant steel is used in construction machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other manufacturing enterprises. It is mainly to provide protection in the occasions or parts that require wear resistance, so that the equipment life is longer, and the maintenance shutdown caused by maintenance is reduced, and the capital investment is correspondingly reduced.
The density of wear-resistant plate is higher than that of some materials, EN 10025-6 high strength steel S500Q, which makes its hardness larger. The density of steel for wear-resistant plate is 7.85kg/dm cubic. After quenching, martensite structure is obtained and tempered at 450-600℃, or 350-600℃ after tempering at 650℃. Or after tempering at 650℃ and heating at 350-650℃ for a long time, the wear-resistant plate will be embrittled. If the brittle wear-resistant plate is reheated to 650℃ and then cooled quickly, the toughness can be restored, so it is also called reversible temper brittleness. High temperature temper brittleness is the increase of the transition temperature from toughness to brittleness.
Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following EN 10025-6 high strength steel S500Q basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.
