STEEL GRADE: ST37.4, ST52.4, ASTM A450, SAEJ524, BS3602 PT CFS360, E235, E355

DELIVERY CONDITIONS

NBK (+N) Normalized. After the final cold forming process the tubes are annealed above the upper transformation point in a controlled atmosphere.

The manufacturing standard adopted for this product is DIN 2391 Standard Series, This type of steel tubes can meet the special requirements of high precision and fine finish steel tubes used in various trades,with the mechanical properties suitable to the bending at any angle and capable of bearing all types of high pressure,cold bending, tube end expansion, bruising, tensile force, impact, impact force etc. , without any occurrence of cracks or crackles, without oxidation scale on the interior or exterior wall of the tubes, without causing any blockage to the pneumatic, hydraulic and oil routes. The percentage elongation and the strength of steel tubes are extremely ideal.
