S420NL carbon steel plate sheet top manufacturer in London

Manganese steel vs carbon plateManganese steel and ordinary steel belong to carbon structural steel and low alloy structural steel. The difference between manganese steel and S420NL carbon steel plate sheet is different in compressive strength, strength and main purpose. In terms of compressive strength, the compressive strength of manganese steel is higher than that of ordinary steel plate. In terms of strength, the strength of manganese steel is also higher than that of carbon steel, and in terms of application, manganese steel plates have more prominent advantages due to the advantages of materials, so the application areas are more common."

The prices of cold rolled sheets and coils products across the country have been on the rise and fall as a whole. On the supply side, the weekly output of cold rolling was basically the same month-on-month, the factory inventory increased slightly, and the social inventory continued to increase. In terms of the market, the national cold-rolled coil prices this week showed a mixed trend. According to local market feedback, as the Spring Festival approaches, the market will have holidays one after another, and the overall transaction has shown a downward trend.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the S420NL carbon steel plate sheet 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 S420NL carbon steel plate sheet quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
