Stainless Steel Wire Grades

300 Series Stainless Steel Wire

300 Series Stainless Steel Wire

300 Series stainless steel wire is a group of stainless steels that are widely used due to their high corrosion resistance, excellent mechanical properties, and good weldability. 


The most common alloys in the 300 series are 304, 316, and 321, and they all belong to the Austenite family of stainless steel. 

Most Popular Grades of 300 Series Stainless Steel Wire


304 Stainless Steel Series
Chromium18%
Nickel8%
PropertiesExcellent corrosion resistance to most oxidizing acids
ApplicationsCommonly used in kitchen equipment, medical instruments, food processing, architectural applications and chemical industries.



316 Stainless Steel Series
Chromium18%
Nickel8%
Molybdenum2%
PropertiesHighly resistant to corrosion, the molybdenum content enhances its resistance to pitting and crevice corrosion.
ApplicationsMarine environments, chemical processing, pharmaceutical equipment, and medical devices.


321 Stainless Steel Series
Chromium16%
Nickel10%
titanium0.5-1%
PropertiesExcellent resistance to oxidation and high-temperature environments (up to about 870°C), Titanium stabilizes the steel, preventing carbide precipitation during welding
Applications321 Stainless Steel is highly valued for its exceptional resistance to oxidation, corrosion, and high-temperature environments, making it ideal for use in industries such as aerospace, chemical processing, food processing, and automotive.


Key Characteristics of the 300 Series

Austenitic Structure: The 300 series has an austenitic crystal structure, which gives it good ductility, formability, and weldability. 

Corrosion Resistance: The 300 series alloys have excellent corrosion resistance, particularly when exposed to moisture and air, making them suitable for both indoor and outdoor applications.

Non-Magnetic: Generally, the 300 series is non-magnetic in the annealed state but may become slightly magnetic when cold worked.


  • 316 & 316L Stainless Steel Wire

    316 & 316L stainless steel wire is a kind of fine wire made of stainless steel, which has the characteristics of corrosion resistance, high temperature resistance and high strength. It greatly improves its corrosion resistance in acidic and chloride environments.

  • 304 & 304L Stainless Steel Wire

    304 and 304L stainless steel wire, also known as 1.4301, X5CrNi18-10 is a common austenitic stainless steel material, 304 & 304L stainless steel wire is a fine wire made of stainless steel. It has the characteristics of corrosion resistance, high temperature resistance and high strength, and performs well in corrosion resistance and strength.
