#18 8 stainless steel vs 304 series#
As the steel does not contain nickel or molybdenum, it is less expensive than any of the 300 series steel.Ĥ30 is a simple corrosion and heat resistant grade and can be used in mildly corrosive conditions or where scaling resistance is required at moderate temperatures.
Being a ferritic material, 430 is liable to brittle fracture at sub-zero temperatures, and cannot be used in cryogenic applications. The steel has limited weldability and should not be used in it's welded condition for dynamic or impact loaded structures. However, the stainless steel has good corrosion resistance in mildly corrosive environments and good resistance to oxidation at elevated temperatures. Type 430 is a low-carbon, plain chromium ferritic stainless steel, often used for kitchen-grade tables and utensils, along with other applications with less anti-corrosion demand. Need Type 316? We have a wide selection of tables, sinks, and lifts in our store. Type 316 is also used extensively for surgical implants. Therefore, this alloy is specified for equipment in the medical industry, pharmaceutical manufacturing, and sterile area. Molybdenum is one of the most useful alloying additives to fight corrosion.īy virtue of the molybdenum addition, Type 316 can withstand corrosive attack by sodium and calcium brines, hypochlorite solutions, phosphoric acid and sulfurous acids used in the paper pulp industry. Molybdenum increases the corrosion resistance of this chromium-nickel alloy, withstanding attack by many industrial chemicals and solvents, and inhibiting chloride pitting. What distinguishes Type 316 from Type 304 is the addition of molybdenum up to a maximum of 3%. The carbon content is held to 0.08% maximum, while the nickel content is increased slightly. Type 316 is also austenitic, non-magnetic, and thermally non-hardenable stainless steel like Type 304. Other types of stainless steel are used for critical environments that require a higher level of resistance to corrosion than Type 304 can offer. It is immune to sterilizing solutions, most of the organic chemicals and a wide variety of inorganic chemicals. Check out our Type 304 tables, cabinets, sinks and more! The stainless alloy resists most oxidizing acids and can withstand all ordinary rusting. This grade is easy to form and fabricate with excellent resistance to corrosion. It is the most readily available in a variety of product forms. Type 304 is the basic chromium-nickel austenitic stainless steel and has been found suitable for a wide range of applications. There are more than 50 stainless-steel grades that are recognized by the American Iron and Steel Institute (AISI.) Three general classifications are used to identify stainless steel.
Other elements are added and the chromium content is increased to improve corrosion resistance, heat-resistance, mechanical properties, and/or fabricating characteristics. Stainless steel isn't a single alloy but rather a group of iron-based alloys containing a minimum of 10.5% chromium. Check out our huge selection of stainless steel equipment for cleanrooms and labs.
