Product information

Brand: SUS321
Standard: JIS G4303/JIS G4311/JIS G4305
‌SUS321 stainless steel is mainly used in high temperature engineering, aerospace, chemical and food processing fields. ‌
In the field of ‌ high temperature engineering ‌, SUS321 stainless steel is widely used in high temperature equipment such as stoves, pipes, nozzles and heat exchangers because of its good corrosion resistance and stability.
In the ‌ aerospace field ‌, SUS321 stainless steel is often used in the manufacture of engines, turbine blades, gas turbines, rockets, missiles and other components because of its excellent corrosion resistance and mechanical strength.
In ‌ chemical industry ‌, because of its good corrosion resistance, SUS321 stainless steel is widely used in petroleum, chemical industry, medicine, metallurgy and other fields of equipment manufacturing.
In the field of ‌ food processing ‌, SUS321 stainless steel is often used in food processing equipment, tableware and so on because of its good hygiene and corrosion resistance.

Product parameter

Chemical composition
The content of ‌ chromium (Cr) ‌ ranges from 17.00% to 19.00%, which has an important influence on the corrosion resistance and hardness of stainless steel.
‌ nickel (Ni) ‌ content range is 9.00%-12.00%, the addition of nickel can improve the corrosion resistance and toughness of stainless steel.
‌ titanium (Ti) ‌ content range is 5xC-0.70%, titanium as a stabilizing element, help to improve the resistance to grain boundary corrosion of stainless steel.
The content of ‌ iron (Fe) ‌ exists in the form of surplus, as the main component of stainless steel, provides the structure and strength of the material.
The content of ‌ silicon (Si) ‌ is 1.00%, and the addition of silicon can increase the hardness of stainless steel.
The content of ‌ manganese (Mn) ‌ is 2.00%, which can improve the hardness and wear resistance of stainless steel.
The content of ‌ phosphorus (P) ‌ and ‌ sulfur (S) ‌ does not exceed 0.045% and 0.030% respectively. The control of phosphorus and sulfur is helpful to improve the purity and corrosion resistance of stainless steel.
‌ carbon (C) ‌ content does not exceed 0.08%, the carbon content has an impact on the hardness and corrosion resistance of stainless steel, but too high carbon content may lead to brittleness, so it needs to be controlled within a certain range.
Mechanical property
Tensile strength ‌ : The tensile strength of SUS321 stainless steel is typically between 520 and 720 MPa, which makes it excellent in applications that require it to withstand tensile forces.
‌ yield strength ‌ : its yield strength is generally between 205 and 275 MPa, which is the maximum stress level before the material begins to produce plastic deformation, which directly affects the reliability and safety of the material.
‌ elongation ‌ : The elongation of SUS321 is usually more than 40%, indicating the degree of deformation that the material can withstand during the tensile process, high elongation usually means that the material has good ductility, suitable for applications that need to resist impact or deformation.
‌ hardness ‌ : The hardness of SUS321 stainless steel is usually evaluated under criteria such as Brinell hardness (HB) or Rockwell hardness (HR), hardness is the material's ability to resist scratches or penetration, and is critical for some applications that require wear resistance.
‌ impact toughness ‌ : SUS321 stainless steel generally has a high impact toughness, suitable for applications that need to withstand impact loads.
