Popular EN steel grade S275NL material grade market price

Q420 steel is a kind of low alloy high strength structural steel. The tensile strength of Q420 steel is 420 MPa. EN steel grade S275NL material, Q420 steel is very suitable to make steel plate, and the strength is much higher than Q235 steel. EN steel grade S275NL material, Q420 steel has high strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance. Q420 steel is suitable for power tower, all kinds of crane, heavy truck, oil derrick, high temperature fan, large electric shovel, dump truck and drilling rig, coal mine hydraulic support, steel structure, etc. application.

The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing EN steel grade S275NL material high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than EN steel grade S275NL material, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.

The principle of stainless steel, the corrosion resistance of EN steel grade S275NL material, stainless steel depends on chromium, it depends on a very thin, solid and fine stable chromium rich oxide film (protective film) formed on its surface, to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the corrosion resistance.
