DIN 15CrNi6 | 1.5919 Case Hardening Steel-DIN 17210

DIN 15CrNi6/1.5919 steel is a low carbon case hardened steel containing Cr-Ni alloying elements as per Germany standard DIN 17210.

As a Cr-Ni series low alloy steel, after carburizing, quenching and low temperature tempering, the surface of DIN 15CrNi6 steel exhibits high fatigue strength, high hardness and wear resistance, and at the same time the core maintains high toughness.

Due to its excellent comprehensive mechanical properties,15CrNi6 steel is mostly used in gear components,and it is also used in the wind power industry.

DIN 15CrNi6 STEEL FORGING

Initial Forging Temperature：1200℃
Final Forging Temperature：800℃
Forging Ratio：above 4:1
Post-Forging Treatment:As an alloy steel with 1.5% Cr and 1.5% Ni, 15CrNi6 steel has high white point sensitivity.Our experience is that annealing heat treatment after forging. It not only eliminates the sensitivity of white spots, but also improves the surface condition and facilitates subsequent processing.
