What are the main forging technologies for 321 stainless steel pipes?


Stainless steel pipes use various stainless steel heat setting and cold-rolled stainless steel pipes, which are commonly used in petroleum, chemical machinery pipelines and stainless steel structural parts for various purposes. In addition to ensuring chemical composition and mechanical properties, what are the main forging techniques for 321 stainless steel pipes?


It is mainly used for the production of unique carbon steel, alloy tool steel and stainless steel heat-resistant steel seamless pipes for high pressure and high working pressure of the hot furnace pipe. This kind of boiler tube is often at high temperature and high pressure. During work, the pipeline will continue to suffer from air oxidation and erosion under the effects of high temperature smoke and water vapor. Therefore, seamless steel pipes are requested to have high durability, compressive strength, high oxidation resistance, and excellent mechanical reliability. , Hydraulic prop pipe.

Stainless steel pipes use a variety of stainless steel plates for heat setting and cold-rolled stainless steel pipes. They are widely used in crude oil, machinery manufacturing pipelines and stainless steel plate construction parts for various purposes. In addition to ensuring the composition and physical properties, they are accepted Seamless steel pipes with fluid mechanics working pressure should ensure that the pressure test meets the standard. All kinds of special-purpose seamless steel pipes must be in accordance with the standards to ensure the standards.

A ferritic stainless steel can resist corrosion in the air or in chemically corrosive substances. The stainless steel plate has a beautiful surface and good corrosion resistance. It does not need to undergo surface treatment such as stainless steel electroplating, and fully utilizes the original stainless steel plate. The surface characteristics of the steel, a kind of steel used in various aspects, are generally called stainless steel plates. It means that there are ferritic stainless steels such as 13 manganese steel and chromium-nickel steel. From the perspective of metallography, because the stainless steel plate has chromium and the surface is composed of a chromium film that is too thin, this film is separated from the intrusion of CO2 in the steel and acts as an anti-corrosion effect. In order to persevere in the original corrosion resistance of stainless steel plates, steel must have more than 12% chromium.

The surface of the 321 stainless steel pipe must be properly cleaned to increase the service life of the 321 stainless steel pipe product and its persistent bright surface. 321 stainless steel pipes have different cleaning cycles in different natural environments. For the long-term application of 321 stainless steel pipe, in order to keep the surface clean and beautiful, it is necessary to clean up and manage it on time.
