ST45 DIN2391-1 Carbon Steel Tube Seamless Precision Hydraulic Steel Pipe
Product Specification
It is DIN2391-1 in the standard. The raw materials of the hydraulic steel pipe are subjected to fine drawing, non-oxidation bright heat treatment (NBK state), nondestructive testing, high-pressure washing and pickling of the inner and outer holes of the steel pipe, rust prevention and rust prevention treatment of the inner and outer walls of the steel pipe, and dust prevention treatment of the two ends of the seal. The steel pipe produced has high precision, good finish, no oxide layer on the inner and outer wall of the steel pipe, the steel pipe can withstand the high pressure of liquid flow, and the cold bending of the steel pipe is not deformed, can be flamed, squished without cracks. Mechanical properties can be bent at any Angle without deformation. It is mainly used for the preparation of steel pipe in the oil pipeline of the hydraulic system, also known as the hard pipe in the hydraulic system. It is used for precision steel pipe for automobile. The specifications are generally the outer diameter (D) φ4mm-76mm and the wall thickness (S) 0.5mm-6.0mm. The length is 6 meters (except customized), and the delivery state is NBK (normalizing), GBK (annealing), BKS (stress relief annealing). The main materials are ST35, ST37.4 (10#), ST45 (20#), ST55 (35#), ST52 (16Mn), which can meet the requirements of high precision, high finish, tensile strength, high mechanical properties of the steel pipe customers.
Advatages
1. High precision, saving the loss of user quantity in mechanical
processing.
2. Specifications, a wide range of applications.
3. Cold rolled finished products with high precision, good surface
quality and good straightness.
4. The inner diameter of steel pipe can be made into hexagonal
shape.
5. Steel pipe performance is superior, metal is relatively dense.
Precision steel tube inherits the advantages of seamless steel
tube, but also has its own characteristics. Using precision
manufacturing ring parts can improve the material utilization rate,
simplify the manufacturing process, save materials and processing
time, such as rolling bearing rings, jack covers, etc., have been
widely used in precision steel pipe manufacturing. The
popularization and application of precision seamless tube is of
great significance to saving steel, improving processing
efficiency, reducing processing process or equipment investment,
saving cost and processing hours, improving production capacity and
material utilization rate, and improving product quality, reducing
costs, and improving economic benefits. Generally, the industry
with high precision requirements uses precision seamless tube, no
precision requirements of most seamless tube, after all, the price
of the same specifications of precision seamless tube is higher
than that of seamless tube.
