    EN10305-2 Welded Steel Tubes , Precision Cold Drawn Steel Tubes for Mechanical

    EN10305-2 Welded Steel Tubes with Precision Cold Drawn Steel Tubes for Mechanical / Automotive Application


    EN10305-2 Welded Precision Cold Drawn Steel Tubes
    Applications: for Auto industry/for Machinery use/Oil Cylinder Tube/Motorcyle Shock Absorber, inner cylinder/Telescopic Cylinders


    Quick Detail:
    Size Range: O.D.:6-350mm W.T.:1-35mm L:max12000mm

    Steel Grade: E195, E237, E275, E355,


    Description:

    ERW+ DOM

    The tubes are manufactured from electric welded pre-tubes by cold drawing or other suitable processes.

    The tubes not include welds used for joining lengths of flat rolled strips prior to forming the pre-tube


    Description:

    Mechanical tubing made from hot or cold-rolled steel.

    Covers electric-resistance-welded low carbon steel tubing for use as mechanical tubing


    Advantage:

    Good concentricity, Better price than seamless.

    aRm: tensile strength; ReH: upper yield strength; A: elongation after fracture
    b 1Mpa=1N/mm2
    c Depending on the degree of cold work in the finishing pass the yield strength may nearly be as high as the tensile strength.
    For calculation purposes the following relations are recommended:
    for delivery condition +C: ReH ≥0.8 Rm
    for delivery condition +LC: ReH ≥0.7 Rm
    d For calculation purposes the following relation is recommended:ReH≥0.5Rm
    e For tubes with outside diameter ≤30mm and wall thickness ≤3mm the ReH minimim values are 10Mpa lower than the values given in this Table
    Note: Special steel grade is also available, according to customer request.
