As a result of improved grade stainless steel board contain more chromium, and costly nickel, molybdenum content is less, the stainless steel of improved grade double photograph that increasing ground uses stainless steel user to provide cost effectiveness more will replace 316 model stainless steel.

Company of science and technology of couplet of smelt metal of business of production of American stainless steel (Allegheny Technologies) expresses, stainless steel of alloy of its AL 2003 had replaced 316L stainless steel in a lot of application domains, generate electricity for example condensation canal, petrifaction heat exchanger, oil and natural gas conduit, and steel structure column and prop up. Stainless steel of this kind of double photograph still is had better be able to bear or endure the function that nod corrode, compare 316 model stainless steel, this product can reduce the product thickness of near 1/3.

Company of smelt metal couplet is Qatar recently (building of housetop of the biggest stainless steel supplied the breaths out an International Airport more world with new Qatar) the AL2003 of 1750 short ton stainless steel.
