Characteristics of Common Stainless Steel Grades
- 304L refers to the low carbon version of 304
- Austenitic stainless steel
- Most common grade of stainless steel used
- Versatile forming and welding
- Corrosion resistant (stress corrosion cracking above 60°C)
- High resistance to heat (up to 870°C)
- Used for applications such as: railings, kitchen appliances, springs, threaded fasteners
- Widely used in the industrial and transportation fields as well
Available Products
- More corrosion resistant than 304 (stress corrosion cracking above 60°C)
- 316L is the low carbon version of 316 – immune to sensitization
- Austenitic stainless steel
- Exceptional welding and forming characteristics
- Widely used for heavy gauge welded components
- Applied in many applications to include: laboratory equipment, springs, railings, fasteners
- Heat resistant up to 870°C
Available Products
- Austenitic stainless steel
- Not as corrosion resistant as 304, due to its sulfur properties
- Ability to withstand mild corrosive environments
- Heat resistant up to 760°C
- Weak welding and forming abilities compared to 304
- Known for its machinability
- Applications include: gears, nuts & bolts, electrical components, aerospace industry, etc.
Available Products
- 17-4PH is sometimes referred to the 630 grade
- Similar properties to 304 – in corrosion and heat resistance
- Martensitic stainless steel
- Excellent corrosion and heat resistance
- Used to make valves and gears
- Difficult to form, unless heat treated
- Typically used in the following industries: chemical, metalworking, aerospace and food processing
Available Products
- Also known for its machinability (highest of all stainless steel grades)
- Moderate resistance to corrosive environments
- Heat resistant up to 760°C
- Low welding properties (welding is discouraged with this grade)
- Uses include: valves, pumps, gears, nuts & bolts, etc.
Available Products
- 440A, 440B, 440C grades (varying carbon contents)
- 440C is the strongest and most resistant out of all of the stainless alloys (after heat treatment)
- 440A is the most rust resistant out of the 3
- Widely used in the industrial field for ball bearings and valves (another common application is knives)
Available Products
- Preferred for use in high temperature environments
- High corrosion resistant
- Heat resistant up to 1040°C
- Good welding and ductility properties
- Common applications include: furnace and oil burning parts, heat treatment and exchangers, etc.
- Austenitic stainless steel
Available Products
- Austenitic stainless steel alloy (nickel-iron-chromium based)
- Used to solve the problems of stress cracking corrosion that can be found in 304 and 316
- Resistant to sulfuric acid
- Used for a variety of applications such as: tanks, valves, food production and numerous industrial applications
