AUSTENITIC STAINLESS STEEL HAVING EXCELLENT SULFURIC ACID CORROSION RESISTANCE AND EXCELLENT WORKABILITY

摘要

An austenitic stainless steel which consists, on a weight basis, of up to 0.05% carbon, up to 1.0 % silicon, up to 2.0 % manganese, upto 0.04 % phosphorus, up to 0.01 % sulfur, 12-27 % nickel, 15-26 % chromium,3.0-8.0 %, excluding 3.0 %, copper, 2.0-5.0 %, excluding2.0 %, molybdenum, up to 1.0 % niobium, up to 0.5 % titanium, up to 5.0 %tungsten, up to 1.0 % zirconium, up to 0.5 % aluminum, below0.05 % nitrogen, up to 0.01 % calcium, up to 0.01 % boron, up to 0.01 % one ormore rare earth elements, and iron and unavoidableimpurities as the remainder. This steel is excellent in the resistance tosulfuric acid corrosion and workability.
