Stainless steel is an iron-carbon alloy with a minimum of 10.5% chromium content. There are different types of stainless steel, containing different proportions of iron, carbon, molybdenum, nickel. It has similar structural properties to steel, although its strength varies significantly.
Type 301—highly ductile, for formed products. Also hardens rapidly during mechanical working. Good weldability. Better wear resistance and fatigue strength than 304. Type 302—same corrosion resistance as 304, with slightly higher strength due to additional carbon. Type 303—free machining version of 304 via addition of sulfur and phosphorus.
The number is in the following format: x.yyzz(zz) Where x is the material type (only 1 is specified so far), yy is the steel group number (specified in EN10027-2) and zz(zz) is a sequential number designated by the certifying body, the number in brackets being unused but reserved for later use. The steel groups are indicated below:
The carbon in typical steel alloys may contribute up to 2.14% of its weight. Varying the amount of carbon and many other alloying elements, as well as controlling their chemical and physical makeup in the final steel (either as solute elements, or as precipitated phases), impedes the movement of the dislocations that make pure iron ductile, and ...
The alloys of aluminum, titanium, and magnesium are valued for their high strength-to-weight ratios; magnesium can also provide electromagnetic shielding. [37] [38] These materials are ideal for situations where high strength-to-weight ratio is more important than material cost, such as in aerospace and some automotive applications. [39]
Researches created an alloy with the strength of steel and the lightness of titanium alloy. It combined iron, aluminum, carbon, manganese, and nickel. The other ingredient was uniformly distributed nanometer-sized B2 intermetallic (two metals with equal numbers of atoms) particles. The use of nickel team avoided problems with earlier attempts ...
Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: no minimum content is specified or required for chromium , cobalt , molybdenum , nickel , niobium , titanium , tungsten , vanadium , zirconium , or any other element to ...
