Types and definitions of stainless steel corrosion
303 and 303Se are free-cut stainless steels containing sulfur and selenium respectively. They are used in situations where easy cutting and high surface brightness are mainly required. 303Se stainless steel is also used to make parts that require hot heading, because under such conditions, this stainless steel has good hot workability.

How are stainless steel pipes classified?
Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, as well as bimetallic composite pipes, coated and coated pipes to save precious metals and meet special requirements. There are various types and uses of stainless steel pipes, with varying technical requirements and production methods. The current production of steel pipes has an outer diameter range of 0.1-450mm and a wall thickness range of 0.01-250mm. To distinguish its characteristics, steel pipes are usually classified according to the following method.

How to determine the specifications of channel steel
The delivery length of channel steel can be divided into two types: fixed length and double length, and the tolerance value shall be specified in the corresponding standards. The length selection range of domestic channel steel is divided into three types based on different specifications: 5-12m, 5-19m, and 6-19m. The length selection range of imported channel steel is generally 6-15m.

Preparation method of carbon steel pipe
The raw material of carbon steel pipe is round tube blank, which needs to be cut and processed by a cutting machine to form a billet with a length of about 1 meter, and then sent to the furnace for heating through a conveyor belt. The billet is fed into the furnace for heating, with a temperature of approximately 1200 degrees Celsius.

What are the characteristics of H-shaped steel?
H-shaped steel is a widely used profile in today's steel structure buildings. The surface of H-shaped steel has no inclination and the upper and lower surfaces are parallel. The cross-sectional properties of H-shaped steel are significantly better than traditional I-beam, channel steel and angle steel. So what are the characteristics of H-shaped steel?

Key points of welding customized stainless steel decorative pipes
In addition to conventional stainless steel decorative pipes, some customers generally choose stainless steel pipes to be customized and processed to meet their own use requirements. However, customized stainless steel decorative pipes are different from ordinary purchased stainless steel pipes, and special attention needs to be paid to some issues.
