S30608 Basic concept and classification of stainless steel materials.
First, the basic concept.
Stainless steel is a metal material with special properties, which has the characteristics of good corrosion resistance, heat resistance, low temperature resistance, high strength and wear resistance. There are many types of stainless steel, among which S30608 stainless steel is a common model that belongs to the austenitic stainless steel series.
S30608 stainless steel is based on 304 stainless steel with 2% molybdenum element added to improve its corrosion resistance and heat resistance. This stainless steel material still has good corrosion resistance in nitric acid at a concentration of 65% below the boiling temperature and has better crevice corrosion resistance. Therefore, S30608 stainless steel has been widely used in chemical, petrochemical, fertilizer, nuclear industry and other fields.
2. Classification. 1.Categorized by organizational structure.
Stainless steel can be divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel and duplex stainless steel according to the organizational structure. Among them, austenitic stainless steel is one of the most commonly used models, including etc. S30608 stainless steel belongs to the austenitic stainless steel series.
2.Classified by chemical composition.
Stainless steel can be divided into chromium-based stainless steel and nickel-based stainless steel according to its chemical composition. Chromium stainless steel uses chromium as the main alloying element, and the chromium content is generally more than 12%. Nickel-based stainless steel uses nickel as the main alloying element, and the nickel content is generally more than 10%. S30608 stainless steel belongs to chromium stainless steel, in which the content of chromium is 18% and the content of nickel is 10%.
3.Categorized by use.
Stainless steel can be divided into corrosion-resistant type, heat-resistant type, low-temperature resistant type, high-strength type and wear-resistant type according to its use. S30608 stainless steel is a corrosion-resistant stainless steel, with good corrosion resistance and heat resistance, suitable for chemical, petrochemical, fertilizer, nuclear industry and other fields.
3. Summary. S30608 stainless steel is a common austenitic stainless steel type with good corrosion and heat resistance, suitable for applications in various fields. For different types of stainless steel materials, the right selection and use need to be made according to their characteristics to ensure their performance and service life.
