EN10305-2 ST37.4 OD5 Hydraulic Cylinder Round Cold Drawn Welded Precision Steel Tube

EN10305-2 ST37.4 Hydraulic Cylinder Round Cold Drawn Welded Precision Steel Tube

Description:

Our EN10305-2 ST37.4 hydraulic cylinder round cold drawn welded precision steel tube is a high-quality, precision-crafted tube for hydraulic systems and cylinder. Made from cold-drawn and welded steel, this tube features, tight tolerances and excellent mechanical properties and a smooth inner surface. Ideal for use in hydraulic systems, industrial equipment and machinery where high pressure resistance and precise control are required.

Advantaged Product Specification:

Delivery Condition:
1. NBK(+N)
after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium
2. GBK(+A)
after cold forming, annealing in non oxidizing medium protective gas
3. BK(+C)
the final heat treatment after cold forming, threfore small steel pipe plasticly, the plasticly degree does not guarantee
4. BKW(+LC)
after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring)
5. BKS(+SR)
have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again
