Low alloy high strength /Seamless steel tubes for structural purposes
Compared with solid steel such as round steel, seamless steel pipe for structure has the same bending and torsion strength and lighter weight. It is a kind of economical section steel, which is widely used in the manufacture of structural parts and mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle frame, construction steel scaffold, etc. It only requires strength and rigidity, but not tightness of steel pipe.

Hot dip galvanized steel pipe low pressure fluid pipeline Q235 A106 A53
Galvanized welded pipe is divided into hot galvanizing and cold galvanizing. The thickness of hot dip galvanizing layer, low cost of galvanizing, the surface is not very smooth. Oxygen blowing welded pipe: it is used for steelmaking and oxygen blowing. Generally, it is small diameter welded steel pipe with 8 specifications of 3 / 8-2 inch. It is made of 08, 10, 15, 20 or 195-q235 steel strip. In order to prevent corrosion, it has to be aluminized.

Precision steel tube bright pipe high precision seamless steel pipe finishing rolling oil pipe
Precision steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer walls of precision steel pipe, no leakage under high pressure, high precision, high finish, no deformation during cold bending, no expansion, flattening and no crack, it is mainly used to produce pneumatic or hydraulic components, such as air cylinder or oil cylinder, which can be seamless pipe or welded pipe.

1045 S45C C45 45# Seamless steel tubes for structural purposes machining
No.45 steel is high quality carbon structural steel with low hardness and easy cutting. It is often used as template, pin and guide post in mould, but it needs heat treatment. Recommended heat treatment temperature: normalizing 850, quenching 840, tempering 600. The content of carbon (c) in its chemical composition is 0.42-0.50%, Si content is 0.17-0.37%, Mn content is 0.50-0.80%, Cr content is less than 0.25%.
