ASTM A321 304 /304L /316/ Precision Stainless Steel Square Tube For High-temperature and General Corrosive
What is stainless steel
Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the passive layer. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.Stainless steel also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced formability and increased corrosion resistance.
Stainless Steel Pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also often used as furniture and kitchen utensils.
What is Square pipe:
Square pipe is divided into seamless steel pipe and Welded Steel Pipe (slotted pipe). According to the section shape, it can be divided into square and rectangular pipes. Circular steel pipes are widely used but there are also some special-shaped steel pipes such as semicircle, hexagon, equilateral triangle and octagon.
Application for square tube
A large number of pipelines are used to transport fluids, such as oil, natural gas, water, gas, steam, etc. in addition,when the bending and torsional strength are the same, the weight is relatively light, so they are also widely used in the manufacture of mechanical parts and engineering structures.
