Characteristics and application scope of P355GH vs p355nh, 12Cr1MoV alloy plate:12Cr1MoV alloy plate is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power station boiler. At 580 ℃, it still has high thermal strength, oxidation resistance and durable plasticity. The production process is simple, the welding performance is good, but it is sensitive to normalizing cooling speed. Pearlite spheroidization will be produced after long-term use at 580 ℃.

NM400 wear resistant steel plate has a very high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; it can improve the wear resistance of mechanical related parts; therefore improve the service life of machinery; reduce production costs. The surface hardness of the product p355gh vs p355nh is usually Reached 360 - 450HB. NM400 wear resistant steel plate is used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled p355gh vs p355nh products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the p355gh vs p355nh rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

We have a professional production team and high-quality production equipment, and we also have a great p355gh vs p355nh advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the p355gh vs p355nh production of high-quality steel plates, steel pipes and other products that meet customer requirements.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
