Definition of stainless steel(Adopted form Wikipedia)

In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable",

is defined as a steelalloy with a minimum of 10.5% to 11% chromium content by mass.

Stainless steel does not readily corroderust or stain with water as ordinary steel does,

but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity,

or poor circulation environments. It is also called corrosion-resistant steel or CRES

when the alloy type and grade are not detailed, particularly in the aviation industry.

There are different grades and surface finishes of stainless steel to suit the environment

the alloy must endure. Stainless steel is used where both the properties of steel

and resistance to corrosion are required.

Q:What is stainless steel decorative tube? What uses does it have?
For the steel to withstand the pressure to the hydraulic test to test its ability and quality, leakage, soaked or expansion for qualified does not occur at the prescribed pressure, some steel according to the requirement of standard or edge test, flaring test and flattening test.Seamless stainless steel tube, also called stainless steel seamless pipe, is made of ingot or solid tube blank by piercing, and then made by hot rolling, cold rolling or cold casting. Specifications for seamless steel tubes are expressed in millimeters of outer diameter * wall thickness.
Q:Mechanical properties of stainless steel tubes
Strength (tensile strength, yield strength) the strength of stainless steel is determined by various factors, but the most important and basic factor is the addition of different chemical factors, mainly metallic elements. Different types of stainless steel have different strength characteristics due to their differences in chemical composition.
Q:304 stainless steel pipe, 20*2 pressure, how many kilograms?
304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability).
Q:SA-179 what kind of material is steel pipe?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:Stainless steel pipe is mainly used in what areas?
Stainless steel pipe is a kind of hollow long strip round steel, mainly used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:Stainless steel works. What saw can be sawed off?
Large quantity resin grinding wheel cutter. A small number of saw blade saw frame quickly is also very labor-saving. Saw blade with fine teeth. The middle teeth and coarse teeth are not suitable, easy to clamp teeth broken teeth.
Q:What kind of welding machine is used for welding thin stainless steel plate and stainless steel square tube?
1 argon arc welding machine! If the person who has not been married, as little as possible, that thing has radiation, long time use of physiology is influential. You know what you do.2, regardless of the front and back can be, as long as it looks beautiful and practical.3, welding technology is good, it will not be ugly after welding.4, only the use of technology to make up for the lack of machinery, and then cattle B hardware, there is no good software is not good.5, welding rod, protective mask and so on.
Q:What's the difference between the stainless steel pipe welded pipe and seamless pipe?
Seamless tube is a strip of steel with a hollow cross section and no seams at all. The general is rolled into a cylindrical tube plate welding.
Q:Why pickling before cleaning stainless steel pipe oil?
Remove the welding slag, dust particles, impurities, oil and other pollutants produced in the installation, so as to avoid polluting the oil products.Avoid polluting oil products.
Q:What are the weld sleeves for stainless steel pipes?
Stainless steel pipe is a kind of hollow long strip round steel, mainly used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
