  • Stainless steel properties & application areas
    Jul 16, 2018


    1. Stainless steel properties  .

    In cases where demands for resistance against utilization environment cannot be met by other more cost-effective metals or substances, stainless steel is an indispensable and reliable material. In addition, stainless steel contains the necessary features and contents to meet the hygiene requirements for air, water, liquid and other chemicals, food and beverage industry.

    Basic characteristics of stainless steel:

    • Resistance against corrosion,
    • Esthetic appeal,
    • Heat resistance,
    • Low life cycle cost (Life Cycle Cost / LCC),
    • Fully recyclable, 
    • Biologically neutral ,
    • Easy production and cleaning ,
    • Weight / endurance ratio

     

     

    2. Part of Stainless steel application areas.


    ASTM CODESPECIFICATIONSAPPLICATIONS
    304Base kind of stainless steel. For mechanical   strength and oxidation up 400°C.Household goods, hollow-ware, catering   equipment, food and process industry equipment, dairy equipment, nitrogen and   hydrogen tanks, metal furniture, car parts and other vehicles, etc.
    304LSame as 304 with low carbon (better   formability).Thick-walled welded structures, strongly   oxidizing envoirements as nitric acid, lining for coal hoppers, liquid   fertilizer spray tanks, tomato paste storage tanks, etc.
    321Useful in higher temperatures and with the   content of titan higher corrosion resistance.Thick-walled welded structures, strongly   oxidizing envoirements as nitric acid, lining for coal hoppers, liquid   fertilizer spray tanks, tomato paste storage tanks, etc.
    316For mechanical strength and oxidation up to 600   °C. Excellent ductility, formability and toughness. Due to the content of Mo   resistant to high oxidation and acid.Textile-brewery-paper-medical and fatty acid   industry, acetic acid compounds, etc.
    316LSame as 316 with low carbon but resistant up to   400°C.Thick-walled welded structures in the same scope   of application as 316.
    316TiThe version of 316, Ti alloyed, resistant to   higher temperatures and oxidations.Thick-walled welded structures in corroding   environments, high temperature applications, developed for highly corrosive   environments in the chemical and process industries and for sea water   applications.
    309SAt 1050 °C higher oxidation resistance.High temperature applications.
    310At 1100 °C higher oxidation resistance.High temperature applications, blast furnace   parts, chemical and petro-chemical industries.
    310SSame as 310 slightly higher resistance.Same as 310.
