35CrMnSiA is a low alloy ultra-high strength steel, heat treatment with good overall mechanical properties, high strength, adequate toughness, hardenability, weldability (preheat before welding), processing and forming are better, but the corrosion resistance and oxidation resistance is low, generally low-temperature tempering or isothermal quenching is used.
35CrMnSiA steel plate implementation standards: the implementation of GB/T 3077-1999 standard.
35CrMnSiA steel plate delivery status: annealed, normalized, normalized tempering, can also be specified according to technical requirements of the delivery status.
