Review of p355gh hardness property price trend

Pageviews:

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the P355GH hardness property quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After p355gh hardness property quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

p355gh hardness property, 13MnNiMoR plate flaw detection and thickness direction performance:13MnNiMoR plate can be produced with additional flaw detection requirements and Z15-Z35 tear resistance (thickness direction performance) requirements. The p355gh hardness property, 13MnNiMoR plates can be tested one by one by ultrasonic testing. The testing method is in accordance with the provisions of GB / T2970 or JB / T4730.3. The testing standard and qualification level shall be indicated in the contract.

The steel grades p355gh hardness property of thick steel plate are basically the same as those of thin steel plate. In terms of steel types, in addition to the bridge steel plate, boiler steel plate, automobile manufacturing steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, some kinds of p355gh hardness property steel plates, such as automobile girder steel plate (2.5-10 mm thick), checkered steel plate (2.5-8 mm thick), stainless steel plate, heat-resistant steel plate, etc., are crossed with the thin plate.
