Stainless steel is the material which is well known for its high corrosion resistance in atmosphere and durability, and, for this reason, it is widely used in many industries. In its constitution, usually there are iron, chromium, nickel, and manganese, as the major constituents. Other elements like molybdenum and nitrogen can also be present but it depends on the grade of steel. The most standard grades are 304, 316, and 430/410 which offer different property set suited for each application. Such as, 304 is widely used in food processing equipment because it has extra impressive resistance to corrosion. In contrast, 316 serves offshore environments well. Within grades of steel, the chemical compositions may differ considerably, and in turn, they will determine the strength, ductility, and weldability of the material. A detailed overview of the composition and tables showing percentage breakdown are available for the engineers, manufacturers, and researchers in a table, chart and PDF file format so that they have the important reference material displaying the characteristics of stainless steel.
Chemical composition of the stainless steel table usually consists of the alloy present in the various grades of stainless steel which contain chromium, nickel, manganese, carbon, silicon, sulfur, phosphorus, sometimes accompanied by molybdenum, copper or titanium. The features play a part in defining the properties of stainless steel such as its resistance to corrosion, strength, and machinability. For example, high chromium content would provide better resistance to corrosion, and nickel will improve the metal’s inherent flexibility and toughness. Different grades consist of individual compositions adjusted to meet the varied applications needs for kitchen supplies to industrial machinery. Such tables are a good point of reference from which one may select the appropriate grade of stainless steel based on specific needs.
