Welding EN 10025 S420M steel plates steel number

Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than EN 10025 S420M steel plates, ordinary carbon steel by adding less alloy elements. Q355GNH weathering steel has been widely used in container, railway vehicle, bridge, building and air preheater which need to be resistant to atmospheric corrosion. Q355GNH weathering steel is characterized by the addition of less Cu, P, Cr, Ni and other alloy elements in the steel, so that a dense amorphous spinel type oxide layer with a thickness of about 50-100μm is formed between the rust layer and the base metal, which can prevent oxygen and water from penetrating into the steel matrix, slow down the development of corrosion to steel materials, and improve the atmospheric corrosion resistance.

16Mo3 alloy are featured by the good heat resistance and corrosion resistance. 16Mo3 steel plate chemical composition(%):C: 0.12 ~ 0.2 Si: ≤0.35 Mn: 0.4 ~ 0.9 P: ≤0.025 S: ≤0.01 Cu: ≤0.3 Ni: ≤0.3 Cr: ≤0.3 Mo: 0.25 ~ 0.35 Al: ≥0.02 N: ≤0.012. 16Mo3 alloy steel mechanical properties:Yield strength (MPa) 372MPa, Tensile strength (MPa) 350MPa, Elongation (%) ≥22. Impact temperature (℃) 20, Impact energy value (J) 335J / cm². EN 10025 S420M steel plates, 16Mo3 steel plate is widely used in petroleum, chemical, power station, boiler and other industries.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.

In December of 2015, our regular India customer sent us an inquiry for EN 10025 S420M steel plates pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.
