Alloy surcharges 2019 March : Spring steel Strip 1.4310 : 1,52Spring steel strip 1.4310 (increased Mo) : 1,65 Spring steel wire 1.4310 : 1,55Stainless steel strip 1.4301 : 1,35Precision steel strip 1.4301 : 1,62Stainless steel wire 1.4301 : 1,64Precision steel strip 1.4404 : 2,46Stainless steel wire 1.4404 : 2,48

Tensile strength according EN 10270-3, table 2 (excerpt for material 1.4310)

Notes:
After straightening the wire the tensile strength can be about 10 % lower.
highest tensile strength = minimum tensile strength + 15% of the minimum
The tensile strength can be increased by heat treatment

Diameter (mm) NS (normal tensile strength), min. HS (higher tensile strength), min.
