  316L stainless steel welded pipe  is a widely used in mechanical equipment, petrochemical equipment, medical equipment, food and light industry pipelines or mechanical parts. There is only one letter difference between 316 and 316L stainless steel welded pipes. What is their essential difference? Now 316 is replaced by 316L stainless steel welded pipe in market. So what is the difference between 316 and 316L stainless steel welded pipe? 1. Cost 316L welded pipe has lower carbon content and is more convenient to weld. Therefore, the price of 316L stainless steel welded pipe is a bit higher than 316 stainless steel welded pipe. In addition, 316L welded pipe can also be called ultra-low carbon 316 stainless steel. 2. Corrosion resistance 316L stainless steel welded pipe has stronger corrosion resistance and is suitable for strong corrosion areas such as seaside and seawater. 3. The difference in intensity The tensile strength of 316L stainless steel welded pipe is higher than 3...

  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...

 What is  310S stainless steel pipe ? 310S stainless steel pipe is a hollow long round steel pipe, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural parts. It is also widely used in the manufacture of mechanical parts and engineering structures. It is often used to produce various weapons, barrels, and shells for stainless steel advantages on bending and torsion strength. What inspection job does 310s stainless steel pipe shoud do before leaving the factory? 310s stainless steel pipes need to do professional inspections before packing, special on mechanical properties. 310s stainless steel pipes include tensile strength and have been tested for yield points to know if the mechanical properties of 310s stainless steel pipes meet the delivery point. The quality of the 310s stainless steel pipe delivered after professional testing is guaranteed. At the same time, the hard...

  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...

  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...

  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...

  There are 3 differences between   304 stainless steel plate   and 316 stainless steel plate: 1. Essentially different The essence of 304 stainless steel: 304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm3, which is also called 18/8 stainless steel in the industry. The essence of 316 stainless steel: 316 stainless steel is a kind of austenitic stainless steel. Due to the addition of Mo, its corrosion resistance and high temperature strength are greatly improved. The high temperature resistance able to reach 1200~1300 degrees, which can be used in harsh conditions.  2. Usage are different: Usage of 304 stainless steel: It is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability). Usage of 316 stainless steel: The main uses are heat exchangers for pulp and papermaking equipment, dyeing equipment, film washing equipment, pipelines, and exterior materials for build...

  The marking of   304 stainless steel plate : The American Iron and Steel Institute uses three numbers to indicate standard grade malleable stainless steel. ①Austenitic stainless steel is marked with 200 and 300 series numbers; ②Ferritic and martensitic stainless steels are represented by 400 series numbers. For example, some of the austenitic stainless steels are marked with 201, 304, 316 and 310; ③Ferritic stainless steel is marked with 430 and 446, and martensitic stainless steel is marked with 410, 420 and 440C, duplex (austenite-ferrite); ④Stainless steel, precipitation hardening stainless steel and high alloys with iron content less than 50% are usually named by trademarks.
