nm400 equivalent material I beams

The steel used for bridge beams should also have excellent welding function and low notch sensitivity, high strength, toughness, and load and impact from rolling stock, as well as outstanding fatigue resistance, certain low temperature resistance, and atmospheric corrosion resistance. Q460qC steel plate delivery status: NM400 equivalent material steel products are delivered in hot rolled, controlled rolled or normalized conditions.

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 equivalent material, 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.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the NM400 equivalent material metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between NM400 equivalent material strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
