75 KDH

Oil tempered SiCrV-alloyed spring wire

75 KDH is especially intended for the manufacture of springs exposed to high static loads or low cycle fatigue applications specially intended for trunk opening springs.

75 KDH is a SiCrV spring steel with elevated tensile strength.

The material has good relaxation properties. The wire is manufactured in sizes from Ø 2.50 to 5.00 mm. Other wire sizes on request.

High tensile
High sag resistance
