SA514 grade P steel material professional supplier in China

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, 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 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,SA514 grade P steel material.

,SA514 grade P steel material., 40Cr material is a common machinery manufacturing steel under GB/T 3077-2015 standard. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28-60mm during water quenching and Ф15-40mm during oil quenching. The cutting performance is better, when the hardness is HB174 -229, the relative cutting workability is 60%.

SA514 grade P steel material,We have 4 typical production lines, which can produce hot rolled Seamless, LSAW, ERW and SSAW pipes. SSAW pipe production line range is OD 219.1mm-3500mm, wall thickness 3.2mm-25.4mm. Product annual capacity is 200 thousand tons.

SA514 grade P steel material,The preparation of galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
