All common materials, e.g. spring steel wire pursuant to EN 10270-1 and -2, stainless spring steel wire pursuant to EN 10270-3, (stainless) spring steel strip with tensile strength of up to over 2,000 MPA, all types of Cu-alloys with various coatings and strengths, cold- and hot-rolled steels.
Internal hardening furnaces for austempering (bainitic hardening) facilitate fracture resistant textures ideal for springs and minimum hardening distortion.
Our external partners are also happy to provide martensitic hardening, vacuum quenching and case hardening.
