A573 Grade 65 structural quality, 40Cr material is a common machinery manufacturing steel under GB/T 3077-2015 standard. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28-60mm during water quenching and Ф15-40mm during oil quenching. The cutting performance is better, when the hardness is HB174 -229, the relative cutting workability is 60%.
In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe A573 Grade 65 structural quality for there cable car supporter.
