Can 304 hot-rolled stainless steel plate be bent
304 stainless steel (06Cr19Ni10) is a steel developed based on 302 stainless steel (12Cr18Ni9). Its performance is similar to 302 stainless steel, but its corrosion resistance is better than 302 stainless steel. It can be used as welded parts with thin cross-sections. It is the stainless steel wi...Read more -
How to control the wall thickness deviation of seamless steel pipes
Among the common problems of seamless steel pipes, wall thickness difference (eccentricity) occupies the first place. Wall thickness difference, as the name implies, is the difference between the maximum wall thickness and the minimum wall thickness. As long as it is a seamless steel pipe, there ...Read more -

Analysis of the Causes of Surface Cracks on Industrial Small-Diameter Seamless Stainless Steel Pipes
Observing the crack morphology, the cracks extend obliquely at an angle of 45° to the inner wall. Since the pipe itself has good mechanical properties and high ductility, it can be ruled out that it is caused by cold rolling. The crack width develops from coarse to fine, and a bifurcation appears...Read more -

The purpose of preheating the spiral steel pipes before welding
Important components of alloy steel and thick parts must be preheated before welding. The purpose of preheating before welding is as follows: (1) Preheating can slow down the cooling rate after welding, allowing hydrogen to diffuse and escape in the weld metal, avoiding cracking caused by hydroge...Read more -
Quality problems in the production process of seamless steel pipes – quality defects and prevention of oil well pipes
The quality defects of oil well pipes mainly come from three aspects: First, the quality defects of the oil well pipe body itself, such as the mechanical properties, internal connection, and weighing of the pipe body that does not meet the requirements; Second, the quality defects caused by the o...Read more -
What are the requirements for the storage of anti-corrosion steel pipes
1. The appearance of anti-corrosion steel pipes entering and leaving the warehouse needs to be checked as follows: ① Check each pipe to ensure that the surface of the polyethylene layer is flat and smooth, without dark bubbles, pitting, wrinkles, or cracks, and the overall color needs to be unifo...Read more -
