Supply the nm400 material specification size specification

We have Business Department, Transportation Department, Document Department, Shipping Department, E-C department, Procurement Department, Finance Department, Human Resources Department, Administration Department, Logistics Department, After-sales so on Departments. Each department performs its own duties, unites and cooperates, and contributes its greatest strength to the overall operation of the company. So as to ensure the stable and sustainable development of the company.

P460NH steel is a normalized weldable fine grain steel. Executive standard: EN10028-3, steel number: 1.8935. P460NH steel is alloy special steel for NM400 material specification pressure equipment. P460NH steel has good plasticity, toughness, cold bending performance and welding performance. P460NH steel plates are usually delivered in normalized condition. According to the negotiation between the supplier and the buyer, normalizing rolling can be used instead of normalizing. In this case, the sample shall be subject to simulated normalizing according to the agreed test frequency to verify that the performance meets the requirements.

ASTM a588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the NM400 material specification yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 NM400 material specification has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the NM400 material specification 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 material specification strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
