What material is 40B steel plate?
40B steel plate is alloy structure steel plate formed by adding boron element into carbon structural steel with 0.40% carbon content. Its hardness, toughness and hardenability are higher than that of 40Cr steel. After quenching and tempering, the comprehensive mechanical properties of 40B steel plate are good, and can replace 40Cr steel.
40B steel plate chemical elements: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.60-0.90, B: 0.0005-0.0035.
40B steel plate is used to manufacture parts with larger cross-section and higher performance requirements than 40Cr steel, such as shaft, tie rod, gear, cam, tractor crankshaft, etc. small section size parts.
