Spring steel
58CrV4 / 1.8161 alloy engineering steel
58CrV4 (1.8161) is chromium-vanadium spring steel and the neighbour of 51CrV4 with higher carbon. The designation is DIN 17221 — EN 10089 carries 51CrV4 (1.8159), not this one.

Springs and preloaded parts where the drawing says 58CrV4.
Limits
If the purchase is to be on a current standard, 51CrV4 is the grade with an EN name. It is not a shaft steel.
Delivery
We source 58CrV4 from European mill partners as round bar, flat bar, square bar, cut to your dimensions and ship the certificate with the material. Typical condition: untreated, soft annealed or +QT. 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
58CrV4 can be supplied with a material certificate to EN 10204, depending on producer, dimension and the requirements specified for the delivery. The heat and the delivery condition are what carry the certificate — a spring or bearing grade only gets its service properties after treatment, and that part is documented by whoever performs it. EN 10204 3.1 can be supplied on a wide range of our materials.
