Common stainless steel types

Everyone's understanding of stainless steel only stays at 304 and 316, so what are the common types of stainless steel?

304 stainless steel

304 stainless steel is a kind of universal stainless steel. Its application is very wide, mainly used in the production of good requirements of comprehensive equipment or machinery. The main comprehensive requirements and standards are the requirements of corrosion resistance. Now it will also appear in family life, such as some small household appliances: meat grinder, thermos cup, washing basin, etc., a 304 stainless steel, which must contain more than 18% chromium and more than 8% nickel, so 304 stainless steel has good corrosion resistance.

316 stainless steel

316 stainless steel, in the basic components of stainless steel, and added Mo, so 316 stainless steel excellent corrosion resistance, but also resistant to atmospheric corrosion. In this way, 316 stainless steel has the advantage of being used under harsh conditions. For example, the equipment used to make or process the need to work in seawater, equipment in chemical environments, dyes, paper, acidic conditions, and so on. There are some slightly expensive children's thermos cups on the market, which are also made of 316 stainless steel material, and are sought after by a considerable number of parents.

410 stainless steel

410 stainless steel is martensitic stainless steel. This stainless steel, different from 304 and 316,410 stainless steel has good hardenability because of its high hardness and toughness, but also corrosion resistance. Thermal force and cold deformation performance, as well as shock absorption performance is also outstanding, yes, that is outstanding. It is also an excellent type of stainless steel and is widely used.

1Cr18Ni9

The name is slightly more complex, corresponding to the United States grade: ASTM A276-96. The biggest feature of this stainless steel is that the carbon content of its composition is about 0.1%, and if the chemical composition is changed on the basis of it, steel with different properties can be obtained.

This stainless steel is more favored by architects and structural designers. Because 1Cr18Ni9 is also known as stainless acid-resistant steel. It also involves a concept of detail: In our practical application, different types of stainless steel, will be used in different environments, different media in the environment, the choice of the type is not the same, we often will be weak corrosion medium corrosion of steel collectively referred to as stainless steel, but in stainless steel, there is a such as 1Cr18Ni9 this just now, is resistant to chemical media corrosion, so this kind of just called acid-resistant steel. But no matter which of these two, they all have the characteristics of rust.

There are many categories of stainless steel, such as 0Cr18Ni12Mo2Ti, stainless steel with different properties can be used for the production of different equipment and the use of different environments.
