High quality nm400 weathering steel grade material for sale

The heat treatment hardness of DC53 mold steel is higher than that of SKD11, NM400 weathering steel, the high temperature is 520-530 ℃, and the high hardness can reach 62-63HRC after tempering. In terms of strength and wear resistance, mold steel DC53 exceeds SKD11 mold steel. The toughness is twice that of SKD11 die steel. The toughness of DC53 is more prominent in cold work die steel. Tools made with DC53 rarely crack and crack, greatly increasing the service life.

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, NM400 weathering steel seamless steel pipes for ships and petroleum cracking NM400 weathering steel steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many NM400 weathering steel products have been exported to the Middle East, India, Southeast Asia and Europe and America.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of NM400 weathering steel, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. NM400 weathering steel, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.
