Stainless Steel Grades: Key Properties and Applications

To help you navigate the world of stainless steel grades, we've compiled a detailed chart that highlights the composition, characteristics, and common applications of the most widely used grades. Let's dive in:

304 Stainless Steel

  • Composition: 18% chromium, 8% nickel
  • Characteristics: Excellent corrosion resistance, durability, and formability
  • Common Applications: Kitchen equipment, appliances, utensils

304 stainless steel, the most popular austenitic grade, offers a perfect balance of corrosion resistance and formability, making it a versatile choice for a wide range of applications.

316 Stainless Steel

  • Composition: 16% chromium, 10% nickel, 2% molybdenum
  • Characteristics: Superior corrosion resistance, especially in chloride environments
  • Common Applications: Marine equipment, medical devices, outdoor furniture

With the addition of molybdenum, 316 stainless steel provides enhanced corrosion resistance, particularly in environments containing chlorides, making it an ideal choice for marine and medical applications.

430 Stainless Steel

  • Composition: 16-18% chromium
  • Characteristics: Good corrosion resistance, magnetic properties, and moderate formability
  • Common Applications: Decorative trim, automotive parts, kitchen sinks

As a ferritic grade, 430 stainless steel offers a combination of good corrosion resistance, magnetic properties, and moderate formability, making it suitable for decorative and automotive applications.
