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, A709 Gr 50S bridge steel plate 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 A709 Gr 50S bridge steel plate 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.
HP295 is mainly used in the manufacture of liquefied gas cylinders, its A709 Gr 50S bridge steel plate chemical composition is stable, P, S content is low, pure steel, the internal organization, fine grain. Moderate strength, good plasticity, low yield ratio, yield platform is not obvious, vertical and horizontal performance of small differences, excellent cold stamping performance.
Compared with A709 Gr 50S bridge steel plate, ordinary steel plate, ship plate has better resistance to wind and wave. In the ocean, there are often big winds and big waves. If the performance advantage of ship plate is not prominent, it is easy to be damaged by big waves. The service life of ship plate is longer than that of ordinary steel plate. Because of its excellent performance, the ship plate can be used for a long time. Some waste ships can remove the ship plate for recycling. The price of ship plate is higher than ordinary steel plate.
Hydrogen (H) is the most harmful element in general steel such as A709 Gr 50S bridge steel plate. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
As per JIS G3101 standard, the Carbon (C), Silicon (Si) and Manganese (Mn) content of SS400 steel plate are not controlled. Phosphorus (P) content of A709 Gr 50S bridge steel plate, JIS SS400 steel plate is 0.050% Max and Sulphur (S) content is 0.050% Max. The SS400 steel melting point is 1430 Degree Celsius, Brinell Hardness is 160HB, density is 7.85g/cm3, Young’s Modulus is 190-210Gpa. The strength and elongation of JIS SS400 steel plate varies with thickness. Generally, the tensile strength of SS400 steel plate is 400-510 Mpa. Elongation is above 21%. Yield strength ≥245Mpa for thickness≤16mm. When the JIS SS400 steel plate is thciker than 100mm, the yield strength shall not less than 205Mpa.
It is a modern high-tech professional enterprise integrating scientific research, A709 Gr 50S bridge steel plate production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as A709 Gr 50S bridge steel plate process technology development, technology transfer and related technical consulting and technical services.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
