Stainless steel 430 is a ferritic, straight chromium, non-hardenable grade, combining good corrosion resistance and formability characteristics with useful mechanical properties. Its ability to resist nitric acid attack permits its use in specific chemical applications but automotive trim and appliance components represents its largest fields of application. Alloy 430 has poor weldability compared to most stainless steels due to the higher carbon content and lack of stabilizing elements for this grade.
Type 420 stainless steel is a general purpose steel and possesses similar qualities to the 410 grade, but contains more carbon which provides improved hardness and strength when heat treated. 420 stainless has good mechanical and machining properties.
Stainless 304, also known as 18-8 stainless, is the most common steel used in a variety of uses because of the ease in which it can be formed into various shapes. Non-magnetic and highly resistant to corrosion makes it a good all-purpose stainless.
17-7 stainless steel is a stable, chromium-nickel-aluminum precipitation hardened stainless steel that provides high strength and hardness, excellent fatigue properties, moderately resistant to corrosion, good formability, and minimum distortion upon heat treatment.
