As a leading hot rolled plate mill in China, We manufacture and export carbon steel and alloy EN10025-4 S275M steel plates steel plates in different sizes and of different thickness. We have an adept and proficient team of professionals in addition to our responsive staff that is ever alert for any customer queries and requisites. If you are experiencing difficulty in selecting the correct EN10025-4 S275M steel plates steel plates for your business, we have a team of experts who can give you the best advice on steel plates, a significant contributor that can flourish your business.

P355NL1 steel tensile strength Rm:630-450MPa.If high demands are made on notch impact strength and aging resistance. It is mainly used in steam boiler and pressure vessel construction. EN10025-4 S275M steel plates, P355NL1 plates can be processed with all known welding methods. Welding is possible both with the machine and by hand. Preheating is usually not necessary unless the outside temperature is below 5°C. Then preheating to about 150°C is recommended.

Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.

The preparation of EN10025-4 S275M steel plates galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for EN10025-4 S275M steel plates centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

StE 480.7 TM steel plate/pipes,under DIN 17172 standard, we can regard StE 480.7 TM steel plate/pipes as large diameter pipes. EN10025-4 S275M steel plates, StE 480.7 TM steel plate/pipes is one mainly of Steel for large diameter pipes,DIN 17172 StE 480.7 TM steel with the demands in mechanical properties of the pipes followed the DIN 17172 specification for grade StE 480.7 TM(YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.

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.
