Stainless Steel 302

Listing ID #41171

TYPE 302 is the fundamental alloy of the austenitic class. It is commonly known as ’18-8’: 18% chromium: 8% nickel : and it is the most commonly used of all the stainless grades. Type 302 is non-hear treatable, but cold working considerably increases both its hardness and tensile strength. Type 302 in the cold state offers great versatility of workability because of its toughness and ductility and can be Tigorously spoun, rolled drawn or machined. It offer outstanding weldability. It is extremely resistant to corrosion, and retains an untarnished silvery surface. It is also resistant to heat oxidation. Drawback of Type 302 is that of sensitization under extreme conditions, carbride precepitation may occur. Type 302 alleviates this problem by decreasing the carbon content and thereby eliminating the possibility of intergranular corrosion. This low carbon alloy is most often utilized for applications requiring welding. An extra low carbon alloy type 304L is also available for especially severe welding applications, type 304L has the capacity to avert any detrimental precipitation in the extreme 800#F 1650#F. range.
Applications :
Both types are extremely popular in the food and dairy industries and for use in pharmaceutical equipment. It is exceedingly useful in applications where good mechanical properties and corrosion resistance are essential. It is highly desirable for products such instrumentation where non-magnetism is fundamental. These grades are available in a wide range of forms and finishers.
Corrosion Resistance :
Type 302, 304 and 304L exhibit good corrosion resistant qualities, particularly those, corrosions caused by atmospheric conditions pr chemicals. They lose some resistance at temperatures of about 750#F to 1500#F due to carbide precipitation. Type 304L however, has excellent corrosion capabilities within this temperature range because of its low carbon content, Maximum corrosion resistance in all these grades can be achieved by annealing.
