Alloy case-hardening steel
15CrNi6 / 1.5919 alloy engineering steel
15CrNi6 is nickel-chromium case-hardening steel. The nickel addition gives a tougher core than 16MnCr5 in heavier material.

What it is used for
Loaded gears and shafts that are carburised.
Limits
17CrNi6-6 or 18CrNiMo7-6 when dimension and requirements rise.
Delivery
We source 15CrNi6 from European mill partners as round bar, flat bar, square bar, cut to your dimensions and ship the certificate with the material. Typical condition: +A / +FP / +TH. From a single cut piece to larger lots — with no minimum charge, so you do not have to buy a full commercial length to get what you need.
Certificates and documentation
15CrNi6 can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. The certificate documents the analysis and the delivery condition — not the finished case hardening, since case and core hardness only arise at the heat treater. If the hardening result is to be documented, that is a separate agreement. EN 10204 3.1 can be supplied on a wide range of our materials.
