What are the characteristics of EN steel grade S355K2 material
Since it was established in 2000. Based on the domestic rich EN steel grade S355K2 material product resources and the great steel demand of the international market, our EN steel grade S355K2 material service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
The company's logistics uses third-party logistics. This logistics model plays an important role in improving the efficiency of our business operations. Third-party logistics is an important form of logistics specialization. As a company specializing in logistics, third-party logistics companies have a wealth of experts who specialize in logistics operations, which is conducive to ensuring the professional production of the company, reducing costs, and improving logistics level of the company. Both the customers and the company benefit from the logystics mode.
We can cut the large steel plates EN steel grade S355K2 material by your requirements, but to the width and length your demand; we can make the surface of the cut steel plate to be bright by milling and grinding, also can make holes and make angle degrees, and can weld by your drawing. For the EN steel grade S355K2 material product thickness under 30mm, we mainly cut by laser cutting; for thickness over 30mm, mainly OXY-cut, flame cutting. The processing plates conclude cutting the larger plate into the small sizes customer demand, cut by drawing, cut to special sizes, weld the cut parts by drawing.
In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
The chemical composition difference between EN steel grade S355K2 material, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between EN steel grade S355K2 material, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
