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 grade HPS50W 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 grade HPS50W 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.
S45C steel plate chemical composition: C 0.42~0.48, Si 0.15~0.35, Mn 0.60~0.90, P≤0.030, S≤0.035, Cu≤0.30, Ni≤0.20, Cr≤0.20 Mechanical properties of A709 grade HPS50W bridge steel plate product Tensile strength>686MPa Yield strength>490MPa Elongation δ5>17% Shrinkage ψ>45% Impact toughness value>78J/cm2 The hardness is 201~269HB.
We have 4 typical production lines A709 grade HPS50W bridge steel plate, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. The Seamless pipe production line range is OD 10.3mm-965.2mm, wall thickness 1.0mm-60mm, Annual capacity is 500 thousand tons. LSAW pipe production line range is OD 406mm-1524mm, wall thickness 6mm-50mm, Annual capacity is 150 thousand tons.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched A709 grade HPS50W bridge steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of A709 grade HPS50W bridge steel plate during tempering, while tempering determines the performance and life of the workpiece.
A588 grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness."When propertly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition. A709 grade HPS50W bridge steel plate, A588 Grade Acould be produced in 200mm in our company.
