What stainless steel sheet products we often see in our lives and how they are classified.

Most of the kitchenware we use now is made of stainless steel, and according to the current trend, all kitchenware will increasingly use such stainless steel products in the future. However, any metal product in the process of use will produce some trace amount of factors that are not good for human health. Stainless steel is the best choice for people’s health, as it produces relatively small amounts of this adverse health factor.
Nowadays, stainless steel has been widely used in our daily life. Our usual kitchen pots and pans, household appliances, etc., many are made of stainless steel. According to the stainless steel tube manufacturer identification: stainless steel in the chemical structure, is made of iron-chromium alloy with certain other metal elements, stainless steel metal function is very good, compared to other metal products, there is better erosion resistance function. At the same time, it has a very good lustre and is aesthetically pleasing.
Stainless steel is an alloy metal material that emerged in the early twentieth century and is characterised by its resistance to corrosion and wear. Since its invention and entry into the market, it has become a new favourite. At present, various products made of stainless steel have become the most common type of utensils in people’s daily life. The next section will bring you information about the types of stainless steel materials.
What is stainless steel?
Stainless steel, as the name suggests, is a steel material that is not easily rusted, and is a type of metal material that is both corrosion resistant and stainless.
Introduction of stainless steel material types
After years of research and development, stainless steel has a variety of classification. Among them, according to the different matrix organization of stainless steel materials, it is mainly divided into.
One, ferritic stainless steel
Ferritic stainless steel is the most common kind of stainless steel material, is a kind of stainless steel in the use of the state of ferrite tissue-based stainless steel. The chromium content of this stainless steel is between 11% and 30%, in addition, it also contains a small amount of molybdenum, titanium, niobium and other elements. In addition to its good corrosion resistance, ferritic stainless steel is characterised by good oxidation resistance, excellent stress resistance, good thermal conductivity and a very small coefficient of expansion. However, the plasticity of ferritic stainless steel is poor, therefore, this kind of stainless steel material is mainly used to make corrosion-resistant parts.
Second, austenitic stainless steel
Austenitic stainless steel is a stainless steel material with a stable internal austenite organization, which contains 18% chromium and 8% nickel, but also contains a small amount of molybdenum, titanium, nitrogen and other elements. This kind of stainless steel material belongs to is the comprehensive performance good product, can resist the corrosion of many kinds of media. Moreover, the toughness and plasticity of austenitic stainless steel are relatively good, at the same time, its easy cutting performance is also very good. At present, austenitic stainless steel materials are widely used in all major industries.
Three, austenitic – ferritic duplex stainless steel
Austenitic – ferritic duplex stainless steel is a kind of internal austenite and ferritic tissue structure of each half of the stainless steel products. It has the characteristics of austenitic stainless steel materials and ferritic stainless steel materials, and compared with ferritic stainless steel, its plasticity is better, higher toughness, compared with austenitic stainless steel, its thermal conductivity is better, the expansion coefficient is smaller.
Four, martensitic stainless steel
Martensitic stainless steel is a hardenable stainless steel material, the biggest feature of this stainless steel material is that the mechanical properties of this stainless steel material can be changed through heat treatment. At present, this kind of stainless steel material is mainly used for steam turbine blades, surgical instruments and other products in the processing of production.
