You can order the stainless spring steel wire as coils, spools or straightened bars. The standard lengths of the straightened rods are one, two or three meters.
The straightened bars can be cut in length according to your wishes.
Beside steel grade 1.4310 we are able to deliver 1.4401 (AISI 316) and 1.4404 (AISI 316L)!

Dimension standard	BS EN ISO 6931-1 (BS EN 10270-3) DIN EN 10218-2 DIN EN 10278
Products	Wire (coils) Straightened rods Wire (spools)
Dimensions	coils/spools: 0,30 mm to 15,00 mm diameter bars: 0,30 mm to 15,00 mm diameter
Tensile strength (Rm)	1250 to 2200 N/mm², depending on the diameter of the wire
Surface	matt shining finish or polished, partial ground and polished
Information	The maximum possible temperature of usage is up to 250°C (dependent upon load). Change in standard: The EN 10270-3 standard was replaced by ISO 6931-1 in November 2020. The following changes have resulted: the material number has changed (the material short name has been retained) lower limit values for tensile strength have been added additional tolerance classes for the diameter of wire in coils and on spools have been introduced.
Heat Treatment	after the forming process of the spring the tensile strength can be increased by heat treatment (a plus of approx. 150 N/mm²) the heat treatment also smoothes out the tensions of the forming process the EN-Standard recommendation reaches from annealing at 250°C for 4 hours to 425°C for 30 minutes; cooling down by air
