Austenitic stainless steels are chrominum-nickel-managanese and chromium-nickel compositions, which can be hardened solely by cold working; heat treatment serves solely to soften them. they're non-magnetic within the annealed condition, though some might become slightly magnetic after cold working. The austenitic group of stainless steels is characterised as having wonderful corrosion resistance, outstandingly good formability, and therefore the ability to develop high streng

Stainless Steel are iron-base alloys containing a minimum of 10.5 percent chormium. There are fifty seven separate and distinct commercial composition designated by America Iron and Steel Institute as standard types. a complete listing of all standard AISI types and a description of each are contained within the AISI publication, “Steel products Manual- stainless and Heat-Resisting Steels.” In addition to the standard AISI types, several special-analysis and proprietary stain

Selection of the proper stainless steel from the various types available needs an evaluation based mostly upon four vital criteria. Listed in order of descending importance, they are: Corrosion Resistance - the first reason for specifying stainless steel. The specifier has to know the nature of the environment and also the degree of corrosion resistance needed. Mechanical Properties - with particular emphasis on heat transfer characteristics and on strength at ambient, eleva
