What it is used for
Gears and shafts where the drawing says 18CrNi8.
Limits
18CrNiMo7-6 is the more widespread modern switch when the Mo addition is specified.
Delivery
We source 18CrNi8 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
18CrNi8 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.
Dimension programme

The range is a delivery programme, not a stock statement. Length is cut to your drawing.
