Description

321 stainless steel pipe is a steel pipe made of 321 stainless steel.

1:321 stainless steel pipe. Seamless steel pipe (GB14976-2002) is used to manufacture superheated steam pipes, boiling water pipes and locomotive boilers of various structures for low and medium pressure boilers, large smoke pipes, small smoke pipes and arch brick pipes. High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel pipes.

2:321 stainless steel pipe: mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel seamless steel pipe for steam boiler pipes with high pressure and above. These boiler pipes are often exposed to high temperature and high pressure. Work, the pipe will also oxidize and corrode under the action of high temperature flue gas and water vapor, so the steel pipe is required to have high lasting strength, high oxidation resistance, and good organizational stability.

3: 321 stainless steel tube adopts steel number: 304321 316 317 310, etc.

4: Alloy structural steel pipes with steel grades of 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; stainless and heat-resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb high-pressure boiler tubes, in addition to ensuring chemical composition and mechanical properties, should be water pressured one by one For the test, a flaring and flattening test is required.

5: 321 stainless steel pipes are delivered in a heat-treated state. In addition, there are certain requirements for the microstructure, grain size and decarburization layer of the finished steel pipe. Seamless steel pipes for geological drilling and oil drilling control; drilling rigs are used to find out the underground rock structure, groundwater, oil, natural gas and mineral resources.

Oil and natural gas exploitation is inseparable from drilling wells. Seamless steel pipes for oil drilling for geological drilling control are the main equipment for drilling, mainly including core outer pipe, core inner pipe, casing, drill pipe and so on. Because the drilling pipe has to go deep into the formation depth of several kilometers, 1cr5mo alloy pipe.

6: The working conditions are extremely complex. The drill pipe is subjected to stress such as tension, compression, bending, torsion and unbalanced impact load, and is also subjected to mud and rock wear. Therefore, the pipe must have sufficient strength, hardness, wear resistance and Impact toughness, the steel used for steel pipe is represented by “DZ” (geological Chinese Pinyin prefix) plus the number one to represent the yield point of the steel. The commonly used steel grades are 45MnB and 50Mn of DZ45; 40Mn2 and 40Mn2Si of DZ50; 40Mn2Mo and 40MnVB of DZ55; 40MnMoB of DZ60, 27MnMoVB of DZ65. Steel pipes are delivered in heat-treated condition.

The difference between 321 stainless steel and 304 stainless steel

321 stainless steel is basically a modified version of 304 stainless steel. The main difference between the two is the fivefold increase in carbon due to the addition of titanium. The addition of titanium helps prevent carbide precipitation during welding and high temperature changes.
Regardless of the wonderful addition of titanium, 321 still has many of the same properties that make stainless steel in the 300 series so great. Common uses for 321 stainless steel are annealing, heavy-duty vehicle exhaust systems, firewalls, stack liners, aircraft components, and other high-temperature service equipment.
