300 Series stainless steels are classified as austenitic, and are hardenable only by cold working methods. These grades of stainless have chromium (approx. 18 to 30%) and nickel (approx. 6 to 20%) as their major alloying additions. Type 304 is the most widely used alloy of all stainless steels. 300 Series Stainless steel alloys resist corrosion, maintain their strength at high temperatures and are easy to maintain.
Stainless steel 304/304L Grade:
Type 304/304L is the modern version of "18-8" stainless steel containing approximately 18% chromium and 8% nickel and is the most commonly specified stainless steel used throughout the world. Type 304/304L is a versatile, general purpose stainless steel with good resistance to atmospheric corrosion, and to many chemicals and food and beverages. These grades can be specified in the annealed condition where they have very good formability. Higher nickel versions can be specified to enhance multi-stage deep drawing characteristics. Higher strength, cold-worked conditions can also be specified for Type 304/304L for spring type applications. Type 304/304L is non-magnetic in the annealed condition but may become slightly magnetic as a result of cold working.
Type 304L can be dual certified as 304 when the composition meets the lower carbon limit of 304L and the slightly higher strength levels of 304. Type 304L should be specified for welded applications as the low carbon version eliminates chromium carbide precipitation and enhances the corrosion resistance in the as-welded condition.
Stainless steel 316/316L Grade:
Type 316/316L is a chromium nickel austenitic stainless steel containing molybdenum. The molybdenum addition enhances the corrosion resistance over that of 304/304L in halide environments as well as in reducing acids such as sulfuric and phosphoric acid. Type 316L can be dual certified as 316 when the composition meets the lower carbon limit of 316L and the slightly higher strength levels of 316. Type 316L should be specified for welded applications as the low carbon version eliminates chromium carbide precipitation and enhances the corrosion resistance in the as-welded condition.
Type 316/316L resists atmospheric corrosion as well as in moderately oxidizing environments. It also resists corrosion in marine atmospheres and has excellent resistance to intergranular corrosion in the as-welded condition. Type 316/316L has excellent strength and toughness at cryogenic temperatures.Type 316/316L is non-magnetic in the annealed condition but may become slightly magnetic as a result of severe cold working.
