What is usage of hardox 500 sheet equivalent steel in China

Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, usage of HARDOX 500 sheet. 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.

The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of usage of HARDOX 500 sheet steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special usage of HARDOX 500 sheet materials and specifications can be ordered in advance.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter usage of HARDOX 500 sheet steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.

30CrMnSiA steel delivery status: usage of HARDOX 500 sheet, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
