Product Details

ASTM A106 sch40 seamless steel pipe tube, st37 st52 cold drawn seamless steel pipe factory

Product Description

Precision bright tube is a kind of high-precision steel tube material processed by ordinary seamless steel tube (or reduced-diameter welded steel tube) through fine drawing or cold rolling.Because the inner and outer walls of the precision bright tube have no oxide layer, withstand high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, flattening and no cracks, it is mainly used to produce pneumatic or hydraulic components, such as cylinders. Or the oil cylinder, which can be a seamless tube or a welded tube.

precision bright tube

The chemical composition of the precision bright tube includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr. High-quality carbon steel finish rolling, non-oxidation bright heat treatment (NBK state), non-destructive testing, the inner wall of the steel pipe is brushed with special equipment and subjected to high-pressure washing, the steel pipe is treated with rust-proof oil for rust prevention, and the two ends are sealed for dust-proof treatment. The inner and outer walls of the steel pipe have high precision and high smoothness.After heat treatment, the steel pipe has no oxide layer, and the inner wall has high cleanliness.The steel pipe bears high pressure, cold bending does not deform, flaring and flattening without cracks, the color of the steel pipe: white with bright, with high metal luster. The precision steel pipes provided by Permanent Steel Manufacturing Co.,Ltd can be used for various complex deformations and mechanical processing.

The main purpose of precision bright tube:
Automobiles, machinery parts and other machinery that have high requirements on the precision and smoothness of steel pipes. The precision bright tube has high precision and the tolerance can be maintained at 2-8 wire. Therefore, in order to save labor, material, and time loss, many machining users are slowly turning seamless steel pipes or round steel into precision bright tubes.

Tempering brittleness of precision bright tube:

After the precision bright tube is quenched to obtain the martensite structure, it is tempered in the temperature range of 450-600℃; or after tempering at 650℃, it passes through 350-600℃ at a slow cooling rate; or after tempering at 650℃, it is tempered at 350-650℃ Long-term heating in the temperature range of ℃ will cause embrittlement of the precision bright tube. If the embrittled 20# precision steel pipe is reheated to 650℃ and then cooled quickly, the toughness can be restored, so it is also called %26ldquo;reversible temper brittleness%26rdquo;high temperature temper brittleness is expressed as the "toughness-brittleness of the precision bright tube" "The increase in transformation temperature. High temperature temper brittleness. The sensitivity is generally expressed by the difference (%26Delta; T) between the "toughness-to-brittle" transition temperature between the toughened state and the brittle state. The more serious the brittleness of high temperature tempering, the higher the ratio of the upper crystal fracture of the precision bright tube.
