High Strength Q420C Steel Plate
Q390B is a low-alloy high-strength steel plate. The steel is easy to process and can obtain certain toughness, plasticity and wear resistance after proper heat treatment. Normalizing can promote tissue spheroidization and improve the cutting performance of blanks with hardness less than 160HBS. Tempering at 550~570℃, the steel has comprehensive mechanical properties.
