The difference between the stainless steel and stainless iron
The difference between the stainless steel and stainless iron, stainless steel usually is the floorboard of the stainless steel, acid steel
Stainless steel is the floorboard of the stainless steel and the acid steel in general. Stainless steel is weak media such as air, steam and water corrosion resistant steel, acid steel is refers to the chemical etching media such as acid, alkali, salt corrosion of the steel. Stainless steel appeared since the turn of the century, has a history of more than 90 years up to now. The invention of the stainless steel is the world's major achievement in the history of metallurgy, stainless steel for the development of modern industry and the development of science and technology progress laid the important material technology base.
Stainless steel grade, different performance, it gradually formed in the process of developing a few broad categories. According to the organizational structure, divided into martensite stainless steel (including precipitation hardening stainless steel), austenitic stainless steel and ferritic stainless steel, austenite and ferrite duplex stainless steel and other four categories; According to some characteristics of the main chemical composition of steel or steel elements to classification, divided into chromium stainless steel, chromium nickel stainless steel, nickel chromium molybdenum stainless steel and low carbon stainless steel, high molybdenum stainless steel, high purity stainless steel, etc.; According to the performance characteristics of steel and use classification, divided into nitric acid stainless steel, stainless steel, sulfate resistance to pitting corrosion of stainless steel, resistant to stress corrosion of stainless steel, high strength stainless steel, etc.; According to the functions and characteristics of the steel, classification, divided into low temperature stainless steel, non-magnetic stainless steel, free cutting stainless steel, superplastic stainless steel, etc. The common method to classification is according to the structure characteristics of steel and steel chemical composition and method of the combination of classification. Generally divided into martensite stainless steel, ferritic stainless steel and austenitic stainless steel, duplex stainless steel and precipitation sclerosis stainless steel, etc., or divided into two categories: chromium stainless steel stainless steel and nickel
Stainless steel are used for anti corrosive environment, and medical equipment and supplies.
So-called "stainless iron", is the recycling of scrap metal, through second oven such as lead, steel processing, through the "zi" is handled and become, the traditional detection method is to use magnets, and this item is unable to distinguish in the traditional way, nature is stolen, and the true national standard SUS304 stainless steel products without market due to high prices.
The "stainless iron" products in the market at present is to have 65% of the share is the price plays an important role, the tensile strength of three kinds of materials are: stainless steel 530 gb - 620 mpa, gb 540-560 mpa, 7075 aluminum alloy "stainless iron" 160-180 mpa. Apparently "stainless iron" tensile strength also amounted to less than a third of the stainless steel strength, is easy to cause of the accident.
