Description
Stainless steel pipe
Stainless Steel pipe (Stainless Steel) is a kind of hollow long cylindrical steel, his scope of application as a pipeline to transport fluids, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. Stainless steel pipes are made of billets of acid and heat resistant grades, which are heated, perforated, calibrated, hot rolled and cut.Classification of stainless steel pipe: stainless steel seamless steel pipe and stainless steel welded steel pipe (welded steel pipe) the basic two categories. According to the outer diameter shape of the steel pipe can be divided into round pipe and shaped pipe, widely used is round steel pipe.
Austenitic Stainless Steel
Austenitic stainless steel has a stable austenite structure, is non-magnetic and has high toughness and plasticity, but its strength is low and it cannot be strengthened through phase transformation. It can only be strengthened through cold working. In addition to being resistant to corrosion by oxidizing acid media, this type of steel can also be resistant to corrosion by sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, etc. if it contains elements such as Mo and Cu. If the carbon content in this type of steel is less than 0.03% or contains Ti or Ni, its intergranular corrosion resistance can be significantly improved. High-silicon austenitic stainless steel has good corrosion resistance to concentrated nitric acid.
Martensitic Stainless Steel
Martensitic stainless steel is a type of stainless steel whose properties can be adjusted through heat treatment (quenching, tempering). In layman's terms, it is a type of hardenable stainless steel. This characteristic determines that this type of steel must meet two basic conditions: first, there must be an austenite phase region in the equilibrium phase diagram, and it must be heated for a long time within the temperature range of this region to allow carbides to dissolve into the steel before quenching to form martensite, that is, the chemical composition must be controlled in the γ or γ+α phase region; second, the alloy must form a corrosion-resistant and oxidation-resistant passivation film, and the chromium content must be above 10.5%. According to the difference in alloying elements, it can be divided into martensitic chromium stainless steel and martensitic chromium-nickel stainless steel.
Duplex Stainless Steel
stainless steel with an austenitic structure at room temperature. Steel contains Cr≈18%, Ni≈8%-25% and C≈0.1%. Steel has high
toughness and plasticity, but low strength.
toughness and plasticity, but low strength.
Ferritic Stainless Steel
It contains 15% to 30% chromium and has a body-centered cubic crystal structure. This type of steel generally does not contain
nickel, and sometimes contains a small amount of Mo, Ti, Nb and other elements. This type of steel has the characteristics of
large thermal conductivity, small expansion coefficient, good oxidation resistance, and excellent stress corrosion resistance.

Products Application
Due to the many great features of stainless steel, it is widely used in many industries. It includes constructions, home
appliances, automobiles, kitchen accessories, mechanical structure, decoration engineering, chemical industry, etc. Let's have a
brief review.
1. Construction & Buildings
It is an essential building material widely used in commercial buildings, bridges, airports, etc. The most common uses include
structural frames, roofing, wall panels, claddings, door panels, backsplash, handrailings, ceilings, elevator hall, inner panels
of elevators, etc. Also, it is perfect for making handicrafts.
2. Automobile
Different grades of stainless steel can be used to manufacture car bodies, grills, trims, wheel axles, bearings, vehicular
exhaust, fuel tanks, etc.
3. Industrial Uses
Stainless steel is ideal for transporting chemicals, liquids, etc. It is typical for medical uses, gas and oil industries, such as
pipelines and tubes, blades, operation tables, pumps, processing or storage tanks & vessels, etc.
4. Household Appliances
About 75% of household appliances are made of stainless steel, including internal panels of cookers, heaters, ovens,
burners,conveyors, grills, television, washing machine, refrigerator, kitchen hardware, etc.
5. Furniture & Daily Uses
Stainless steel coil and sheet are also versatile in our daily life, such as trash cans, screens, benches, tables, beds,
bookshelves, advertising boards, display stands, etc.
