A588 grade B high strength steel,API 5L X42 steel plate (L290) is pipeline steel. API 5L X42 steel yield strength is 290 - 495 MPA, and the yield ratio is not more than 0.9. The A588 grade B high strength steel delivery status of API 5L X42 steel plate is hot rolling or controlled rolling API 5L X42 steel plate (L290) is mainly used for the production of oil and gas gathering and long-distance pipelines or coal and building material slurry pipelines, to serve for transportation of gas, water and oil in the natural gas industry,A588 grade B high strength steel.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This alloy steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness,A588 grade B high strength steel.
Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.
A588 grade B high strength steel,NM500 wear plate is Chinese abrasion resitant steel. NM500 steel is equivalent to AR500, HARDOX500, XAR500 and so on materials. The surface Brinell hardness of NM500 wear plate is ≥470 HBW. The NM500 steel is consists of max. 0.38% Carbon, 0.70 Silicon, 1.70 Manganese, 0.020 Phosphorus, 0.010 Sulfur, 1.20 Chrome, 1.00 Nickel, 0.65 Molybdenum, 0.050 Titanium, 0.0005-0.006 Boron, min. 0.010 Als, etc.. According to GBT24186, the max. thickness of NM500 wear plate is 70mm.A588 grade B high strength steel
