Best quality cheap SM520C carbon steel plate sheet

Medium thick plate refers to the steel plate with a thickness of 4.5-25.0mm. Those with a thickness of 25.0-100.0mm are called thick plates, and those with a thickness of more than 100.0mm are extra thick plates. Medium thick plate SM520C carbon steel plate sheet is a kind of flat steel with large width thickness ratio and surface area. The main materials of medium thick plate are Q235, Q345, S355JR, etc. The company not only provides raw steel materials, but also provides cutting and so on processing services for medium and thick plates, extra thick plates and wide and thick plates.

If the chromium content in SM520C carbon steel plate sheet alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.

The final heat treatment of quenched and tempered alloy steel, SM520C carbon steel plate sheet is quenching and high temperature tempering. The hardenability of quenched and tempered alloy steel is high, and oil is generally used. When the hardenability is very high, it can even be air cooled, which can reduce the defects of heat treatment. The final properties of quenched and tempered alloy steel depend on tempering temperature. Generally, it is tempered at 500 ℃ - 650 ℃. The required properties can be obtained by selecting tempering temperature. In order to prevent the second kind of temper brittleness, fast cooling (water cooling or oil cooling) after tempering is beneficial to the improvement of toughness.
