What is the effect of LR grade D seafaring ship steel surface treatment on its properties

At the same time, the company operates a variety of products of related iron and LR grade D seafaring ship steel steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained LR grade D seafaring ship steel ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

15MnNi steel plate is used for nuclear safety second and third grade pressure vessel steel. Since nuclear power equipment is used in harsh environments such as high temperature, high pressure and neutron radiation all year round, the steel LR grade D seafaring ship steel for equipment manufacturing is required to have suitable strength, high toughness, and low brittle transition temperature. The characteristics of strong performance and anti-radiation ability and low alloy element content, so there are strict requirements in room temperature stretching, high temperature stretching, thickness direction stretching and hardness.

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 LR grade D seafaring ship steel 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.

Between alloy wear-resistant layer and the substrate of wear-resistant steel is metallurgically bonded. Through special equipment and automatic welding process, high-hardness self-shielding alloy welding wire is uniformly welded on the substrate, and the number of composite layers is one to two or even multiple layers. During the compounding process, due to the different alloy shrinkage ratio, uniform transverse cracks occur. It is a distinctive feature of wear-resistant steel plates, LR grade D seafaring ship steel.

LR grade D seafaring ship steel 2020 spot size: 16*1800*6000, 15*2500*10000, 25*2400*8200, 50, 25*2400*8200, 16*2000*10713, 25*2400*8200, 16*2270*11900, 15*2500*10000, 25*2400*8200, 28*2170*13000, 130*2200*7700, 100*1770*6650, 88*3440*9200, 12*2200*8000, 8*2200*5730, 16*2320*10000, 30*2400*9680 12*2200*8000, 16*1800*6000, 50*1820*10700, 130*2200*7700.
