Surface heat treatment methods for A387 GR.12 CL.2 pressure vessel steel sheet

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

45Mn2 steel is added with manganese on the basis of No. 45 steel. After quenching and high temperature tempering, 45Mn2 steel can obtain high strength and good toughness, that is, it has good comprehensive mechanical properties, and is often used in manufacturing larger load shafts, connecting rods, fasteners, etc. The price of 45Mn2 steel is higher than that of No. 45 steel, A387 GR.12 CL.2 pressure vessel steel sheet. And the performance of 45Mn2 steel after heat treatment is better. 45Mn2 steel can be used as parts under higher stress and wear conditions, such as universal joint shaft, axle, connecting rod cover, friction plate, etc. The performance of 45Mn2 steel after heat treatment is better than No. 45 steel and worse than 40Cr steel.

The alloy layer of clad wear-resistant plate is mainly made of chromium carbide, and it is also equipped with molybdenum, niobium, titanium, boron and other components. The formation of multi-element carbides also has strong stability at high temperatures and can still be maintained below 500 °. High hardness and good oxidation resistance. The new clad wear-resistant plate A387 GR.12 CL.2 pressure vessel steel sheethas multiple performances of wear resistance, corrosion resistance, temperature resistance and impact resistance.

Tempering the important A387 GR.12 CL.2 pressure vessel steel sheet welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve A387 GR.12 CL.2 pressure vessel steel sheet strength, plasticity and toughness.
