With a quality between hard drawn spring wire and music wire, moderately priced HLT is excellent for springs without servere bends. 


The material is cold drawn to the desired size and heat treated by a continuous tempering method. A low temperature stress relief is required after processing. Wire is available is size ranges from 0.30 - 16mm.


Steel Tempered In Oil And Quenched For Mechanical Springs En 10270-2



Mechanical Characteristics And Specifications

Oil tempered steel wire is achieved by heating the workpiece to a high temperature and then cooling it in an oil bath. 


This hardens the material and improves its resistance to deformation and abrasion. We have available a wide range of chemical compositions of quenched and tempered steel wire based on the EN 10270-2 standard which applies to quenched and tempered spring steel wires.


In the mechanical characteristics section of the product data sheet you can find out what each type of hardened steel wire is used for, as well as the tensile strength of all of them. 


The inner and outer diameter measurements and the weight of the coil according to the nominal value in millimetres are also detailed.
