Product Name STKM11A steel pipe STKM12A steel pipe STKM13A steel pipe STKM13C steel pipe STKM14B steel pipe
chemical analysis C:≤0.12;Si:≤0.35;Mn:≤0.60;P:≤0.040; S:≤0.040 C:≤0.20;Si:≤0.35;Mn:≤0.60;P:≤0.040; S:≤0.040 C:≤0.25;Si:≤0.35;Mn:0.30-0.90;P:≤0.040;S:≤0.040 C:≤0.25;Si:≤0.35;Mn:0.30-0.90;P:≤0.040;S:≤0.040 C:≤0.30;Si:≤0.35; Mn:≤0.30-1.00;P:≤0.040; S:≤0.040
Tensile Strength ≥290MPa ≥340MPa ≥370MPa ≥510MPa ≥500MPa
Yield strength - ≥175MPa ≥215MPa ≥380MPa ≥355MPa
Standard JIS G3445
Length As customer's request
Packaging Standard export packing, packed in woven bags, with two nylon slings, or can be customized as request
Heat Treatment/      Delivery Condition Cold finished (hard)   BK(+C)
Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation
Cold finished (soft)    BKW(+LC)
The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding)
Cold finished and stress-relieved annealing BKS(+SR)
Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree.
Annealed    GBK(+A)
The last Cold forming process is followed by annealing in a controlled atmosphere.
Normalized   NBK(+N)
The last cold forming process is followed by annealing above the upper transformation point in a controlled atmosphere.
Delivery Time Within 35-50 days from receiving deposit
Payment Term 100% L/C at sight or 30% deposit, 70% balance against copy of B/L
Usage/Application Pipes for automobile and motorcycle
Main Market Asia, Middle East, Europe, etc.
