Standing at a new historical starting point, we adapt to the requirements of supply side EN 10025 S420M steel plate structural reform, adhere to the overall strategy of "innovation driven, quality leading, quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the International leading EN 10025 S420M steel plate steel materials supplier.
Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, EN 10025 S420M steel plate. The main differences according to the classification are as follows: A needs no impact test, B needs room temperature impact test (20 degrees above zero), C needs zero degree impact test, D needs minus 20 degree impact test, and E needs minus 40 degree impact test. The most important characteristic of manganese steel plate is that under the condition of strong impact and extrusion, the surface layer rapidly hardens, but the core still maintains good toughness and plasticity, and the hardened layer has good wear resistance.
Spring steel has good fatigue strength and can be restored to its original state after repeated use, without deformation, because the spring has good ductility and can be changed back to the original state no matter how long it is stretched. EN 10025 S420M steel plate, Spring steel has good elasticity. Spring steel can not only be made into springs, but also be processed into swords, which requires good elasticity. The tensile strength of spring steel is good, it will not break and can be recovered under the condition of tensile limit.
Different from EN 10025 S420M steel plate, 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.
There are various weather resistant steel materials in the world. Their thickness ranges are distinct. For JIS G3125 weathering steel sheet, typical grades are SPA-H / SPA-C, the max. thickness is 16mm. For TBT 1979 weather resistant steel sheets, typical grades are 09CuPCrNi-A / 05CuPCrNi, the max. thickness is 20mm. For EN 10025-5 steel, typical grades are S355J0WP / S355J2WP / S355J0W /S355J2W, the max. thickness is 100mm. The max. thickness for EN 10025 S420M steel plate, ASTM A588 steel plate is 200mm. And the max. thickness for ASTM A242 steel plate is 100mm.
