  316L stainless steel pipe  is a hollow long round steel pipe. It is an important product in the iron and steel industry. It is divided into two categories according to the way of consumption: seamless pipe and welded pipe. It is safe and reliable, sanitary and environmental friendly, economical and applicable, and resistant to air. It is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transportation pipelines and mechanical structures in daily life etc. So how is the compression of 316L stainless steel pipe connected? 1. Pipe cutting: Cut the pipe according to the required length. When the pipe is broken, do not use excessive force to avoid the pipe from being out of round. 2. Removal burrs: After the pipe is cut, the burrs should be removed cleanly to avoid cutting the sealing ring. 3. Marking: In order to insert the steel pipe completely into the socket of the pipe fitting, it is necessary to draw a line on...

The Welding Influence on Stainless Steel Angle Bar

图片
  Stainless steel angle bar  is a kind of angle bar, it is used in all field, such as food production equipment, chemical equipment, nuclear energy, etc. Welding is need in production of stainless steel angle bar. Practice shows that welding will not only affect the strength of stainless steel angle bar, but also increase the strength of stainless steel angle bar, making it play a very important function and effect in the application. Specifically because: The higher the carbon content of stainless steel angle bar, the higher its strength and the lower its plasticity. For every 0.1% increase in carbon content, the yield strength σs increases by approximately 27.4Mpa; the tensile strength σb increases by 58.8-78.4Mpa; the elongation δ decreases by 4.3%, and the reduction of area ψ decreases by 7.3%. The strength of angle bars is the ability of angle bars to withstand external loads under different environmental conditions. The tensile strength is one of the important indicators...

Reasons for the Corrosion Resistance of 316L Stainless Steel Pipe

图片
  316L stainless steel pipe  is lpopular in consumers for its long service life, high temperature resistance and corrosion resistance. However, lots of people do not know why 316L stainless steel pipe has such good corrosion resistance. Today, HCADTO Stainless Steel Co., Ltd. will simply introduce it to you: the reason for the corrosion resistance of 316L stainless steel pipe. The surface of all metals changes with the oxygen in the air, forming an oxide film on the metal surface. The difference is that the iron oxide formed on the surface of ordinary carbon steel will continue to oxidize, leading to continuous expansion of corrosion, and eventually formation of holes. The surface layer of 316L stainless steel pipe will react with oxygen, but because of its high chromium content, the key to the corrosion resistance of 316L stainless steel pipe is the chromium content. When the chromium content of 316L stainless steel exceeds 10.5%, the corrosion resistance of 316L stainless st...

Characteristics of Cold Rolled Stainless Steel Plate

图片
  Cold rolled stainless steel plate  is a stainless steel plate produced by cold-rolling process. The thin plate is thickness ≤ 3mm , and the thick plate is thickness> 3mm. Used to make corrosion-resistant parts, pipelines, containers, medical equipment, marine equipment, etc. of petroleum and chemical industry. Cold rolled stainless steel plates are processed based on hot-rolled stainless steel plates. The processing process: hot rolling→pickling→cold rolling. Because of the cold rolled is made by continuous cold deformation, the mechanical properties are poor and the hardness is too high. It must be annealed to restore its mechanical properties. Those without annealing are called rolled hard coils. Rolled hard coils are generally used to make products without bending or stretching. Characteristic of cold rolled stainless steel plate 1. Cold-rolled stainless steel plate has a certain degree of work hardening, low toughness, and much expensive; 2. The surface of cold-rolled...

The Difference between 304 Stainless Steel Plate and 316 Stainless Steel Plate
