Product Description
GB/T13793 Cutting Chamfer Automotive Tube Q235 Q345 SPCC SPHC Welded Steel Tube
Application:Dashboard, Seat, Anti-collision Beam, Cylinder Shock Absorber, Door (Thermoform Tube)
size:L--2~12m OD--10~76mm WT--0.5~4mmmm
Manufacture method:The steel pipe shall be made of hot rolled steel strip or cold rolled steel strip by high frequency resistance welding method
Delivery State:Steel tube should be welding or heat treatment state delivery
Grade:Q235 Q345 SPCC SPHC HC340/590DP B340/590DP HC340LA HC380LA HC420LA HC410LA HC500LA S355MC S500MC S550MC S600MC S700MC SAPH440 QSTE340TM QSTE380TM QSTM420TM QSTE500TM ST37-2G ST52-2G CR340LA CR380LA CR420LA DC01 DC02 DC03 DC04 DC05 STKM11A STKM12A STKM12B STKM12C STKM13A STKM13B STKM14A STKM14B STKM14C
Surface Quality:The internal and external surfaces of the steel tube are not allowed to have cracks, scabs, folds, delaminations, laps, and burns. Allows for scribes, scratches, misalignment of welds, burns, oxide scales, and external burr removal traces that are not more than a negative wall thickness deviation
Advantages: Good mold material, high quality of coolant and other production materials
