Cold drawn carbon spring steel wire
COLD-DRAWN NON-ALLOY STEEL WIRE FOR SPRINGS
Adapted to the manufacture of static load and dynamic load application of mechanical spring cold drawn carbon spring steel wire.
Classification and marking of steel wires Intensity level, load type and diameter range
Strength class Static load Nominal diameter range / mm Dynamic load Nominal diameter range / mm
Low tensile strength SL type 1.00 to 10.00 - -
Medium tensile strength SM type 0.30 ~ 13.00 DM type 0.08 ~ 13.00
High tensile strength SH type 0.30 ~ 13.00 DH type 0.05 ~ 13.00
Note: the table S, D, respectively, represents the static load and dynamic load; L, M, H, respectively, representing low tensile strength, moderate tensile strength and high tensile strength; table code is the first spring load classification code, The bit is the tensile strength grade code.
Dimensional tolerances
Wire diameter control range: d<4.00mm: ± 0.02mm; d: 4.00mm: ± 0.03mm;
Not roundness: not more than half of the diameter tolerance
Surface Quality
The surface of the steel wire shall be smooth and shall have no defects which may adversely affect the use of the wire, such as drawing, tearing, rusting, etc. For dynamic load spring wire (DM and DH), the depth of the crack or other surface imperfections in the radial direction shall not Is greater than 1% of the nominal diameter of the wire; the radial depth of the partial decarburization is not greater than 1.5% of the nominal diameter of the wire.

Winding test
Nominal diameter of less than 3.00mm wire winding test, the diameter of the wire diameter is equal to the mandrel on the tight winding at least four times, does not appear any cracks

delivery status
The wire is delivered as a coil
