The company attaches great importance to systematic management, and has passed the corten steel S355J2G2W ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on corten steel S355J2G2W 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%.
The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of corten steel S355J2G2W cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.
From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. corten steel S355J2G2W, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.
The microstructure of the quenched and tempered alloy steel, corten steel S355J2G2W after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.
