Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important EN10025-4 S275M steel heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

ASTM A572 Grade 50, used in large-scale construction, EN10025-4 S275M steel is an extremely strong alloy with a yield strength of 65,000 psi, an allowable bending stress of 39,000 psi and a future as the high-performance replacement of ASTM A36 steel.

EN10025-4 S275M steel, low alloy high strength steel has good atmospheric corrosion resistance and is widely used in engineering structure construction. Most of the engineering structures are used in the atmosphere or marine environment. A small amount of Cu, Ni, Cr, P and other elements are added to the low alloy high strength steel, which effectively improves the corrosion resistance of the engineering structure in the atmosphere, sea water and soil. If 0.2% - 0.5% copper, 0.05% - 0.1% phosphorus and aluminum are added, the corrosion resistance of steel can be improved obviously, and the effect of adding copper and phosphorus at the same time is the best.

Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as EN10025-4 S275M steel, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.

Chemical composition of 12Cr1MoV alloy steel plate: Carbon C: 0.08-0.15; Silicon Si: 0.17-0.37; Manganese Mn: 0.40-0.70; Sulfur S: allowable residual content ≤ 0.035; Phosphorus P: allowable residual content ≤ 0.035; Chromium Cr: 0.90-1.20; Nickel Ni: allowable residual content ≤ 0.030; Cu: allowable residual content ≤ 0.030; V: 0.15-0.30; Mo: 0.25-0.30.Delivery status of EN10025-4 S275M steel, 12Cr1MoV alloy steel plate: delivered in heat treatment (normalizing, annealing or high temperature tempering) or non heat treatment status, and the delivery status shall be indicated in the contract.

The alloy steel plate is among our business scope, and it is one of our main product. If you have any demands or questions about alloy steel plate, such as 34CrMo4 EN10025-4 S275M steel material properties, 42CrMo4 AISI equivalent, 12Cr1MoV equivalent ASTM, 40Cr material specification, 42CrMo hardness, 50CrMo4 chemical composition and so on, please free free to communicate with us. We have professional technical team and sales team, who will give you EN10025-4 S275M steel professional answers and quotation about alloy steel plate in time.

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.
