Welcome to BBN High Strength Steels Factory
EN10025-3 S420N material is a welded low alloy steel grade. Its mateiral number is 1.8902. This steel shall be done low temperature charpy V impacting test under EN10025-3 standard, the temperature shall be -20℃, and the impacting energy shall be min 27J. For EN 10025 S460Q high strength steel, S420N steel plate quality, our company will supply various testing for our clients like size and quantity checking, the chemical analysis, ladle analysis, tensile test, impact test, and ultrasonic testing.
Our company has EN 10025 S460Q high strength steel strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply EN 10025 S460Q high strength steel deep processing service for products EN 10025 S460Q high strength steel like cutting, drilling, bending, welding and grinding.
The EN 10025 S460Q high strength steel steel making furnace can only be used as primary refining, and the refining needs to be completed in the refining equipment outside the furnace, which is also called secondary refining. It is mainly through decarburization, desulfuration, denitrification and dephosphorization to improve the cleanness of the steel, to establish a chromium molybdenum low alloy steel with good oxidation resistance and high temperature strength, to remove unwanted harmful impurities from the steel, and to improve the EN 10025 S460Q high strength steel internal quality of the steel.
Different from EN 10025 S460Q high strength steel, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.
