ASTM A572 Grade 50, used in large-scale construction, A283 Gr D mild steel coil is an extremely strong alloy with a yield strength of 65,000 psi, an allowable bending stress of 39,000 psi and a future as the high-performance replacement of ASTM A36 steel.
The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, A283 Gr D mild steel coil steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and A283 Gr D mild steel coil carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.
After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to A283 Gr D mild steel coil full material. Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality. In early 2008, the company established the Ministry of foreign trade, and our A283 Gr D mild steel coil steel plate products are now exported to the South Asia, the Middle East, Europe and the United States.
The allowable temperature of A283 Gr D mild steel coil, boiler steel is mainly determined by strength condition. Different steels have different mechanical properties and high temperature properties. Even for the same kind of steel, the tensile strength, yield strength and rupture strength vary greatly with the working temperature, and decrease with the increase of working temperature. In order to ensure the safety of A283 Gr D mild steel coil work, the actual stress of A283 Gr D mild steel coil under the working temperature should be less than the allowable stress determined by the tensile strength, yield limit and permanent strength of A283 Gr D mild steel coil under the temperature.
Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
