Side-by-side chemical composition and mechanical property comparison.
Overview
22MnB5
1.5528
THE press hardening (hot stamping) boron steel — used in virtually every modern car for B-pillars, bumper beams, and side impact reinforcements. As-delivered: ferritic-pearlitic, UTS 450-750 MPa, formable. After hot stamping + die quenching: fully martensitic, UTS 1300-1650 MPa. Boron (0.002-0.005%) provides critical hardenability at low cost. Usually AlSi or Zn coated to prevent oxidation during austenitizing at 880-950°C.
41Cr4
1.7035
Medium-carbon chromium steel with good hardenability. Standard grade for induction-hardened and nitrided components. Used for crankshafts, gears, axle shafts, bolts, studs, and machine parts requiring surface hardening.
