Steel material D6A cold rolled steel strip for band saws
Guangzhou Cgood Steel Co., Ltd is a professional manufacturer, supplying saw blade steel strip material D6A with good flatness and good straightness. D6A steel is an alloy steel containing chromium, molybdenum, cobalt, nickel and other elements. Its chemical composition has an important influence on its performance. Generally speaking, the chemical composition of D6A steel should meet the following requirements:
D6A steel composition
Carbon: 0.4%-0.5%,
Chromium: 0.7%-1.2%,
Molybdenum: 0.2%-0.5%,
Cobalt: 0.2%- 0.4%,
Nickel: 1.5%-2.5%.
The microstructure of D6A steel is mainly composed of martensite, bainite and residual austenite. Among them, martensite is a kind of organization with high hardness and brittleness, while bainite has high toughness and plasticity. Therefore, during the heat treatment process, it is necessary to control the organization structure through reasonable process parameters to achieve the ideal performance requirements.
Performance requirements of D6A steel
D6A steel has excellent high temperature strength, high toughness and high wear resistance, so it is widely used in band saws, aviation, aerospace, automobile, machinery and other fields. In practical applications, the performance requirements of D6A steel mainly include the following aspects:
1. High strength: D6A steel has high yield strength and tensile strength, and can withstand large loads and impact forces.
2. High toughness: D6A steel has high toughness and plasticity, and is not easy to break when subjected to impact or vibration.
3. High wear resistance: D6A steel has high surface hardness and can resist wear and corrosion.
Heat treatment process of D6A steel
The treatment process of D6A steel mainly includes annealing, cold rolling, quenching and tempering. These steps can eliminate the internal stress of steel parts, refine grains, improve organization, and improve the plasticity and toughness of steel.
