SA572 Grade 65 steel material,,SA572 Grade 65 steel material., 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%,SA572 Grade 65 steel material.

Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, and so on.
