Carbon Precision Steel Tube SAE1020 BS6323/4 For Hydraulic System

Description:

Standard:DIN2391/C/EN10305-4 /SAEJ524/BS6323/4 Material:ST35,ST37.4,ST37,ST45,ST52,ST52.4,E235,E255,E355,SAE1010,SAE1020 Delivery State:NBK/GBK. Raw material:Bao Steel,Huai Steel,XingCheng Steel with good quality. Length:5.8m,6m. Package:Bundles or wooden cases. Surface Anti-rust:Both outside and internal tube surface flushing with anti-rust oil. Surface quality:very smooth and bright without oxide scale,pock,strach,crack and other defects.. Surface Cleaness:clean without iron scrap,dust,better for hydraulic system life. High working pressure,better extending rate and strength property,after bending with no deformation,after flattening and flaring process with no crack. Raw material:?Precision tubes are made from carbon steel from quality Bao Steel,XingCheng Steel,and HuaiSteel.

Manufacturing Process:

Synopsis of Process Routing: Quality Carbon steel — Cold Drawn — Heat Treatment Without Oxidization (NBK Status) — Nondestructive Testing— Flushing The Internal Hole With Special Equipment Under The High Pressure —Dealing With Antirust Oil On Surface — Plastic Capping On Both Ends. Inner and Outer Surface Cleaning: We adopt automatic inner surface cleaning machine, rotating brush cleaning and high pressure oil flushing to clean the inner and outer surface.The new steel tube production craftsmanship can effectively remove all particulate attached to the inner and outer surface of tubes and thus achieving the utmost surface cleaness and polishness. Finished tube anti-rust oil plating: We adopt high pressure spray plating method, the antirust oil is plated by high pressure jet after ten passes of filtering and one pass of precipitation to safeguard the tubes’ outer and inner surface cleaness and polishness.
