S35020 austenitic stainless steel (2Cr13Ni4Mn9) has good formability and corrosion resistance. It is one of the most widely used stainless steel grade for different applications. High molybdenum and nitrogen content promotes slightly higher strength and corrosion resistance than other grades of stainless steels.
S35020 austenitic stainless steel is primarily composed of iron and chromium, with traces of other elements such as manganese and nickel. This grade of stainless steel comprises quite a wide range of different stainless steels, but all share common trait of high levels of anti-corrosive properties.
Due to its high chromium and molybdenum content, S35020 austenitic stainless steel is considered to have excellent corrosion resistance in a range of mild to moderately corrosive environments. It therefore has many applications in industries including food processing, dairy and brewing, chemical processing, food storage and transportation, outdoor structures, and other chemical, oil and gas processing applications.
S35020 austenitic stainless steel also has good formability, with good ductility and certain plasticity even in cold environments. The excellent plasticity makes S35020 suitable for weight-bearing components of fine and large parts, making it suitable for highly stressed components in medical, automotive, petrochemical and other processing industries.
S35020 austenitic stainless steel also has good welding properties. It can be welded in all standard positions with a variety of welding techniques, although no special heat treatment is generally required. Its weldability makes it suitable for a wide range of applications, including manufacture of pipe components and tubular components, hot-dip galvanized parts, and structural components such as building equipment, vessels, and transportation materials.
The tensile strength of S35020 austenitic stainless steel is determined by the nickel and molybdenum content. At 25 °C (77 °F), the ultimate tensile strength for the 2Cr13Ni4Mn9 steel grade is 615 MPa (90 ksi). The grade is also fairly resistant to impact, with an average Charpy impact value of 25 J at -20 °C (-4 °F). The resistance to fatigue is also excellent, and distortion is minimal during welding.
S35020 austenitic stainless steel can also be cold worked to modify its yields and tensile strengths, as well as its formability and ductility characteristics. Cold working can be performed in a range of different ways, including rolling, stretching, and folding. The high corrosion resistance and low cost make S35020 an ideal choice for parts and components which need to be both aesthetically pleasing and durable.
In conclusion, S35020 austenitic stainless steel (2Cr13Ni4Mn9) is a versatile steel grade which offers excellent formability and corrosion resistance. Its composition of alloying elements gives it the tensile strength and fatigue resistance required for difficult and demanding applications. This makes it suitable for a range of industries and applications including chemical handling, petrochemical, food and beverage, and many more.
