Stainless steel square tube is a hollow strip of steel with a square cross-section, so it is named square tube. It has excellent corrosion resistance, heat resistance and low temperature strength, and has the advantages of beautiful, environmental protection, not easy to rust, etc., and is widely used in construction, machinery, petroleum, chemical industry, electric power, food, medical and other fields.

Stainless steel square pipes can be classified according to different materials, specifications, surface treatment methods, etc. According to the material classification, stainless steel square pipe can be divided into stainless steel seamless pipe and stainless steel welded pipe; According to the specification classification, stainless steel square pipe specifications and sizes are diverse, can be customized according to different needs; According to the classification of surface treatment, stainless steel square tube can be divided into polishing tube, wire drawing tube, mirror tube and so on.

The manufacturing process of stainless steel square pipe mainly includes round steel preparation, heating, hot rolling perforation, cutting head, pickling, grinding, lubrication, cold rolling processing, degreasing, solution heat treatment, straightening, pipe cutting, pickling, finished product inspection and other steps. In the manufacturing process, it is necessary to strictly control the process parameters and material quality to ensure the mechanical properties and appearance quality of the stainless steel square pipe.

Stainless steel square pipe has a wide range of applications. For example, it can be used as a pipeline to transport fluids, such as oil, natural gas, water, gas, steam, etc. In the field of machinery manufacturing, it can be used to manufacture a variety of conventional weapons, gun barrels, shells, etc. In the field of architecture, it can be used to make curtain walls, railings, stairs and so on. In addition, due to the high bending and torsional strength of stainless steel square pipes, while the weight is light, it is also widely used in the manufacture of mechanical parts and engineering structures.

1.4319 steel pipe is a kind of metastable austenitic stainless steel pipe.

4319 steel pipe can obtain high strength and hardness through cold processing, while maintaining enough toughness, and has good corrosion resistance under atmospheric conditions. It is mainly used for equipment and components that require high loads, light weight and are not easy to rust, such as railway vehicles, conveyor belts, bolts, nuts and fasteners.

1.4372 steel pipe is a ferritic stainless steel, also known as 201 stainless steel.

4372 steel pipe contains 17% chromium, 4.5~6.5% nickel, 0.15% carbon and 5.5~7.5% manganese, with good corrosion resistance and heat resistance, often used in the manufacture of building materials, kitchen utensils, chemical equipment, electrical accessories and so on. The main characteristics of 1.4372 steel pipe include good corrosion resistance and oxidation resistance, appropriate nickel and manganese content, excellent workability and weldability, good heat resistance and wear resistance. In addition, it can also change its mechanical properties and surface finish through cold working and heat treatment.

It should be noted that 1.4372 steel pipe is prone to intergranular corrosion at high temperatures, so it should be avoided in high temperature environments.

310S stainless steel pipe is a kind of stainless steel pipe with excellent oxidation resistance at high temperature.

310S stainless steel pipe has excellent oxidation resistance and corrosion resistance due to its high chromium and nickel content, and can withstand the erosion of high temperature oxidation and corrosion environments. In addition, it also has good creep strength, can continue to operate at high temperatures, so it is widely used in petroleum, chemical, electric power, food, pharmaceutical and other fields.

310S stainless steel pipe manufacturing process mainly includes hot rolling, cold rolling and so on.

316Ti stainless steel pipe is an austenitic stainless steel pipe, which contains titanium in its chemical composition, so it is called 316Ti.

316Ti stainless steel pipe has excellent corrosion resistance, high strength and good welding performance, and is widely used in petroleum, chemical, food, medicine, paper and other fields. Specific features are as follows:

Corrosion resistance. It has good tolerance to chloride ions, and can maintain long-term stability and corrosion resistance in harsh environments such as Marine environment, industrial acid and alkali solutions and high temperature steam.
High strength. It has high strength and yield point, can withstand greater pressure and bending stress, and is not easy to deformation and fracture.
Good weldability. In the welding process, it is not easy to crack, porosity and slag inclusion, and the welded joint has good corrosion resistance and mechanical properties.
High temperature performance. Able to maintain its mechanical properties and corrosion resistance at higher temperatures.

Stainless steel pipe is a tubular product made of stainless steel material, with excellent corrosion resistance, heat resistance, low temperature strength and mechanical properties, while with environmental protection, beautiful, not easy to rust and other advantages, is widely used in construction, machinery, petroleum, chemical, electric power, food, medical and other fields.

The manufacturing process of stainless steel pipe mainly includes hot rolling, cold rolling, cold drawing, etc., and its cross-section shapes are diverse, such as round, square, flat, hexagonal and octagonal, etc., and the use of different shapes of stainless steel rods is not the same.

Stainless steel pipe has good corrosion resistance, according to the different use of the environment, you can choose different materials of stainless steel pipe, such as 304 stainless steel pipe, 316 stainless steel pipe, etc. At the same time, stainless steel pipe also has excellent heat resistance and low temperature strength, suitable for a variety of high and low temperature environments. In addition, stainless steel pipes also have the advantages of beautiful appearance, not easy to rust, and are widely used in various decorative and architectural structures.
