The company attaches great importance to systematic management, and has passed the GL-A hot-rolled steel strip ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on GL-A hot-rolled steel strip quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
GL-A hot-rolled steel strip, Cold-rolled ordinary strip steel is mainly used for making bicycles, sewing machines, agricultural machinery and other accessories and hardware products. Hot-rolled high-quality strip steel is mainly used as a blank for cold-rolled strip steel, and can also be used to manufacture bicycles, sewing machine parts and hardware manufacturing. The cold-rolled high-quality steel strip is suitable for manufacturing various stamping parts, steel pipes and other metal products.
The clad steel plate is based on carbon structural steel, which is sprayed with stainless acid resistant and heat-resistant steel on the surface. The clad steel plate is widely used to make acid and alkali resistant container. Advantages of clad steel plate: The appearance of the clad steel plate is very smooth, the quality is very good, and it will not rust. Disadvantages of clad steel plate: the GL-A hot-rolled steel strip, clad steel plate has better requirements for production technology and are more expensive.
Chromium molybdenum steel, also known as medium temperature hydrogen resistant steel, refers to the steel added with Cr (≤ 10%), Mo and other alloy elements to significantly improve the high-temperature strength limit and creep limit, and has good hydrogen corrosion resistance and high-temperature resistance performance. GL-A hot-rolled steel strip, Chromium molybdenum steel is widely used in oil refining, chemical and other hydrogen containing devices and high-temperature equipment, and is one of the commonly used steels for pressure vessels.
Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with GL-A hot-rolled steel strip, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.
