Stainless steel is a type of alloy steel that resists corrosion due to its
chromium content of 12% or more. In the presence of oxygen, chromium oxide
is formed, which creates an inert film on the steel surface that protects
the entire product from adverse effects. The modern market can offer
different grades of stainless steel for use in a wide variety of industries.
Types of steel of the 300 series
In terms of its chemical composition, chrome-nickel stainless steel of this group is austenitic, austenitic-ferritic and austenitic-martensitic, depending on the percentage of carbon, nickel, chromium and titanium. It is the most versatile stainless steel, the properties of which provide it with a consistently high demand in the market.
AISI 304 (08Х18Н10)
Demanded in all branches of industry, this stainless steel, however, has gained fame "food". Its chemical composition and properties make it the most suitable for use in the food industry. It is easy to weld and exhibits high corrosion resistance in aggressive environments. It is also often chosen for the chemical, pharmaceutical, petroleum and textile industries.
AISI 316 (10Х17Н13М2)
316 stainless steel is obtained by adding molybdenum to 304 stainless steel, which further increases corrosion resistance and the ability to retain properties in aggressive acidic environments, as well as at high temperatures. This stainless steel is more expensive than 304 and is used in the chemical, oil and gas and shipbuilding industries.
AISI 316T (10Х17Н13М2Т)
This grade of stainless steel contains a small amount of titanium, which increases the strength of the material, making it resistant to high temperatures, as well as to chlorine ions. It is used in welded structures, for the manufacture of gas turbine blades, in the food and chemical industries. Affordable price and high technical characteristics make this stainless steel very popular.
AISI 321 (12-08Х18Н10Т)
Stainless steel, the characteristics of which are due to the high titanium content. Easily weldable, resistant to temperatures up to 800 o C. Widely in demand for the manufacture of seamless pipes, as well as pipe fittings - flanges, tees, bends and transitions.
Types of steel 400 series
This series has a narrower range than the 300. It includes stainless steel with a high chromium content - it contains almost no other alloying elements, which has a positive effect on its cost. The low carbon content makes these stainless steel ductile and weldable.
AISI 430 (12Х17)
It is stainless steel with a high percentage of chromium and a low percentage of carbon. This ratio contributes to high strength and ductility at the same time. AISI 430 bends well, welded, stamped. Retains its properties in corrosive and sulfur-containing environments, resistant to sudden changes in temperature. It is used in the oil and gas industry, as well as a decorative material for finishing buildings and premises.
Types of steel 200 series
So far, we can only talk about one steel grade in this series, but it is successfully catching up with its competitors in the 300 and 400 series.
AISI 201 stainless steel is much cheaper than other series of stainless steel similar in properties. In it, expensive nickel is partially replaced by manganese and nitrogen. Beneficially balanced chemical composition makes the characteristics of AISI 201 stainless steel not inferior to AISI 304 and AISI 321. It has found its application in medical and food.
