Stainless Steel

one_21 Stainless Steel – Grade 304 (UNS S30400)
Chemical Formula: Fe, <0.08% C, 17.5-20% Cr, 8-11% Ni, <2% Mn, <1% Si, <0.045% P, <0.03% S
Grade 304 is the standard “18/8” stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics.
Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components

2. Stainless Steel – Grade 202
Grade 202 stainless steel is a type of Cr-Ni-Mn stainless with similar properties to A240/SUS 302 stainless steel. The toughness of grade 202 at low temperatures is excellent.
It is one of the most widely used precipitation hardening grades, and possesses good corrosion resistance, toughness, high harness, and strength.
The grade 202 steel can be made into plates, sheets, and coils to be used in the following:

  • Restaurant equipment
  • Cooking utensils
  • Sinks
  • Automotive trim
  • Architectural applications such as windows and doors
  • Railway cars
  • Trailers

3. Stainless Steel – Grade 316
Chemical Formula Fe, <0.03% C, 16-18.5% Cr, 10-14% Ni, 2-3% Mo, <2% Mn, <1% Si, <0.045% P, <0.03%
It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Grade 316 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
Grade 316L, the low carbon version of 316 and is immune from sensitization and is extensively used in heavy gauge welded components.
