Stainless steel model
Stainless steel types are usually defined by a standardized numbering and naming system to identify different types and alloys of stainless steel. Different international standards and organizations use different numbering systems, the most common of which are ASTM (American Society for Testing and Materials), AISI (American Iron and Steel Institute), EN (European Standards), JIS (Japanese Industrial Standards) and DIN (German Industrial Standards) standards) etc. Here are some common stainless steel models:
AISI 304: Also known as 18-8 stainless steel, it is a common austenitic stainless steel used in food processing, kitchen equipment, and decorative materials.
AISI 316: Has higher corrosion resistance and is commonly used in marine environments and chemical industry equipment.
AISI 430: Ferritic stainless steel, often used in applications where high corrosion resistance is not required, such as automotive exhaust pipes.
AISI 201: An austenitic stainless steel with moderate corrosion resistance used in decorative materials and household equipment.
AISI 420: Has higher hardness and wear resistance, usually used for cutting tools and machine parts.
EN 1.4404 (X2CrNiMo17-12-2): A commonly used European standard stainless steel used in the chemical industry, food processing and pharmaceutical equipment.
EN 1.4016 (X6Cr17): A ferritic stainless steel used in household appliances and general purposes.
JIS SUS304: Austenitic stainless steel in Japanese Industrial Standard, similar to AISI 304.
DIN 1.4571 (X6CrNiMoTi17-12-2): Stainless steel with titanium element, resistant to high temperatures and corrosion, commonly used in chemical equipment.
These models represent only a small selection of stainless steel varieties. The choice of stainless steel depends on the requirements of the specific application, including corrosion resistance, strength, thermal properties, magnetism and processability. Therefore, when selecting stainless steel, its properties often need to be carefully considered to meet the needs of the application.
