Alloy steel plate/sheet nm500 gb standard sheet
With the development of China's NM500 gb standard sheet market economy, the company vigorously implements the strategy of industrialization, internationalization and diversification, promotes group operation, intensive development and lean management, and builds the company into a company with scientific development concept, continuous innovation vitality, excellent corporate culture and strong sense of social responsibility through rich series of NM500 gb standard sheet products and project portfolio and complete operation network And international first-class competitiveness of modern enterprises.
The steel grades NM500 gb standard sheet of thick steel plate are basically the same as those of thin steel plate. In terms of steel types, in addition to the bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some kinds of NM500 gb standard sheet steel plates, such as automobile girder steel plate (2.5-10 mm thick), checkered steel plate (2.5-8 mm thick), stainless steel plate, heat-resistant steel plate, etc., are crossed with the thin plate.
The application of AR400 abrasion resistant steel plate: NM500 gb standard sheet, AR400 abrasion resistant steel plate is mainly for wear exposed structures use, such as protective pads, shell walls for prospectors and bulldozers. AR400 abrasion resistant steel plate is also used to fabricate the supporting or reinforcing plate, the cutting plate for truck rollover, mixing elements and conveying elements, chute grooves, machine tools, crushers and shredders, waste briquetting presses, blades, paving abrasives and agricultural machinery.
Try to use NM500 gb standard sheet high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the NM500 gb standard sheet temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. NM500 gb standard sheet, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.
