| Message: | 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 |
