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.
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.
