The necessary conditions and classification of 310S stainless steel pipes

The 310S stainless steel tube is a circular hollow steel strip, widely used in industries such as petroleum, chemical engineering, medical care, food processing, light industry, and mechanical instruments. When the bending strength and torsional strength are the same, it is lightweight and is widely used for manufacturing mechanical parts and engineering structures.

Now, let the Yongding Stainless Steel Tube Factory introduce to you the essential conditions of the 310S stainless steel tube: 310S is an austenitic chromium-nickel alloyed stainless steel, with excellent oxidation resistance and corrosion resistance. The higher the chromium-nickel ratio, the better the creep strength of 310S, which can continue to work at high temperatures and has good high-temperature performance. 310S stainless steel is suitable for manufacturing various furnace components. The high working temperature is 1200℃, and the continuous use temperature is 1150℃.

The surface of 310S stainless steel tubes is divided into industrial surface and semi-glossy surface. One type of stainless steel tube has a surface marked as 310S, which merely undergoes matte finish treatment. Apart from being the same as the ordinary 310S stainless steel tubes, the processing method is as follows: Pour 1:1 matte liquid into the working solution. Heat the electrolyte to 40-50℃ at room temperature. Hang the lead plate or stainless steel plate on the cathode, fix the workpiece to be polished on the anode, adjust the voltage to around 5V, and polish for 3-5 minutes before removing the workpiece. The semi-light electrolysis technology has been completed.

Process flow: Chemical degreasing, rust removal water washing, electrolytic ice water washing, neutralizing water washing, hot water and pure water washing. 310S stainless steel seamless pipes can be classified into seamless stainless steel pipes, oil well pipes (such as casing, tubing and drill rods), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic pillar pipes, high-pressure gas cylinder pipes, geological pipes, chemical pipeline (high-pressure fertilizer pipes, petroleum cracking pipes) and ship pipes according to different uses.

The 310S stainless steel seamless pipes are divided into stainless steel seamless steel pipes and stainless steel welded steel pipes (welded pipes). Depending on the manufacturing process, they can be classified as hot-rolled, extruded, cold-drawn and cold-rolled. According to the cross-sectional shape, they can be divided into round pipes and special-shaped pipes. Round steel pipes are widely used, but there are also some special-shaped stainless steel pipes such as square, rectangular, semi-circular, hexagonal, equilateral triangular, octagonal, etc.

The 310S stainless steel pipe is widely used and is also known as stainless steel pipe. It is made by piercing a steel ingot or solid steel billet, and then through hot rolling, cold rolling or cold drawing. The specifications of seamless pipes are indicated by outer diameter * wall thickness (in mm). This article is from the Internet.
