equivalent grades of nm450 steel Vs A 36 Steel

At the same time, the company operates a variety of products of related iron and equivalent grades of NM450 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 equivalent grades of NM450 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.

41Cr4 (1.7035) material is an alloy structural steel grade commonly used internationally. Its tensile strength, yield strength and hardenability are all higher than that of 40# steel, but it also has certain defects that its weldability is limited and there is a tendency to form cracks. 41Cr4 steel is generally used for more important quenched and tempered parts, such as parts that work under alternating loads, medium speed and medium load parts.

Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, equivalent grades of NM450 steel.

The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the equivalent grades of NM450 steel material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this equivalent grades of NM450 steel steel grade.

S500MC steel plate/sheet,EN10149 S500MC steel plate/sheet, under EN standard, we can regard S500MC steel plate/sheet as high yield strength steels for cold-forming steels. equivalent grades of NM450 steel, EN10149 S500MC is mainly used as high yield strength steels for cold-forming steels. The EN10149 S500MC steel is equivalent to SEW092 QStE500TM, NFA E490D, UNI FeE490TM and ASTM X70XLK steel grades.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
