What is the difference between EN steel grade S275JR material and steel grade A36

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional EN steel grade S275JR material production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of EN steel grade S275JR material leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

16 Mn is a major steel grade of high strength low alloy steel plate in most industries, The consumption of this type is very large. Its intensity is higher than the ordinary EN steel grade S275JR material carbon structural steel Q235 by 20% ~ 30%, atmospheric corrosion resistance by 20% ~ 38%.

Advantages of NM360 wear-resistant steel plate: NM360 steel has high strength: generally its yield strength is above 300MPa. 2. High toughness: The elongation is required to be 15% -20%, and the room temperature impact toughness is greater than 600kJ / m ~ 800kJ / m. For large welded components, high fracture toughness is also required. 3. NM360 steel plate has good welding performance and cold forming performance. 4. Low cold and brittle transition temperature.

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as EN steel grade S275JR material. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.
