Stainless steel wire for springs, held to excellent mechanical properties — surface, cast and helix — and supplied from 0.19 mm to 1.20 mm in bright finish and 0.50 mm to 6.0 mm in matte finish (coated), in grade AISI 302, 304, 316 and 321, to Standard ASTM A313 and others.
Stainless Steel Wire for springs has following Characteristics
Stainless Steel wire for spring is made from the selected steel. In particular to provide optimum spring efficiency, this type of wire is painstakingly finished to eliminate flaws.
Chemical composition. Available in complete range of Stainless Steel as per AISI, DIN, JIS and BS standards.
The model below is the wire itself at the gauge you select — drag it to turn it in space, and switch between the delivered coil and a cut length with the cross-section exposed. Tensile strength, elongation, diameter tolerance and ovality all resolve with it.
Diameter tolerance band. Mechanical properties are quoted for the 0.71 – 1.60 mm band.
Ovality of the wire. The arithmetic difference between the two measurements of the diameter shall be not more than half the tolerance specified in table 1.

These nominal values are the lower limits of strength. The upper limits are equal to the lower limits in addition to the tolerance specified in table 2.
This test applies only to wire of nominal diameter between 0.5 mm inclusive ad 3.7 mm inclusive. For wires of nominal diameter less than 0.5 mm.
The wire shall withstand without breaking the minimum number of reverse bends specified in table 3 for the appropriate diameter, tensile grade and finish. The radius of curvature of the supports for the various wire diameters is also given.
If the tensile grade of a wire lies between two tensile grades given in table 3, then the number of reverse bends for the next upper tensile grade shall be chosen. Note: The reverse bend test is not mandatory for wires to correspond with this international standard.
Minimum number of reverse bends. Columns under Quality B are tensile grades 1770, 1960 and 1570 N/mm; the last column is Quality A at 1570.
