Surface heat treatment methods for SA572 grade 42 carbon steel plate sheet

HARDOX steel SA572 grade 42 carbon steel plate sheet is a famous wear-resistant steel brand. It is designated as Hardox400, hardox450, hardox500, hardox600. It has good wear resistance in general and special applications.

42CrMo steel plate is an ultra-high strength steel plate, which is widely used in machinery manufacturing steel. The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness. 42CrMo steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness.

If the chromium content in SA572 grade 42 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.
