Stainless Steel Alloys

Corrosion Resistant / Wide Range of Applications


Common Sheet Alloys and Their Characteristics:

  • 301, 302 and 304 stainless steel
    • Good corrosion resistance.
    • Easy to form and weld.
    • Annealed or work hardened at the mill to produced 1/4 hard, 1/2 hard and full hard tempers for a wide range of applications in all industries.
    • Not heat treatable.
  • 316 stainless steel
    • Very good corrosion resistance - food handling and medical applications.
    • Easy to form and weld.
    • Annealed or work hardened at the mill to produced 1/4 hard, 1/2 hard and full hard tempers for a wide range of applications.
    • Not heat treatable.
  • 410 stainless steel
    • Secondary plating processes are often used to improve moderate corrosion resistance characteristics.
    • Easy to form.
    • May only be purchased in annealed condition.
    • Heat treating may be done after manufacturing processes are completed,  Post HT hardness, RC39-43 with bright finish.  Lower hardness is achieved by tempering, which has the negative effect of heat treat scale.
    • Remains relatively stable in heat treating as compared with high carbon spring steels.
    • Applications in all industries.
  • 420 stainless steel
    • Similar to 410 stainless steel above, with higher possible hardness, up to RC55
  • 17-7 stainless steel
    • Secondary plating processes are often used to improve moderate corrosion resistance characteristics.
    • May be purchased in annealed condition, which is easy to form, or in condition C (work hardened at the mill)
      • For annealed material, there are limited options for heat treating (TH950, TH1050, RH950), yielded different results, depending on desired performance.
      • Condition C material may be heat treated to condition CH900, obtaining the highest hardness/strength characteristics possible with 17-7 stainless steel.
    • Applications in all industries.
  • 17-4 stainless steel
    • Similar to 17-7 stainless steel with slightly lower, final hardness and strength characteristics.
    • Simple and cost effective heat treatment.
