p295gh steel material as rolled, killed

Hydrogen (H) is the most harmful element in general steel such as P295GH steel material. 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.

We do sand blasting and shop primer for various p295gh steel material steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer p295gh steel material thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.

The company produces and export steel plates and steel section products of various materials all year round. The width of the p295gh steel material thin plate is 500 - 1500 mm; the width of the thick plate is 600 - 3000 mm. Steel plates are classified by steel type, including ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, etc .; according to use, there are shipbuilding plate, pressure vessel plate, wear resistant steel plate, bridge builidng steel, corten steel plate, and pipeline steel plate.

P355GH is the European standard pressure vessel plate and sheet. The implementation standard: EN10028-2:2003. p295gh steel material, EN p355gh steel plate and sheet has good plasticity, toughness, cold bending performance and welding performance, suitable for manufacturing nuclear island steel containment, pressure vessels, equipment structural parts, etc. It is delivered in hot rolled, normalized + tempered condition.
