Characteristics of alloying elements in Stainless Steel

Stainless steel basically iron alloyed to carbon with certain additional elements to give the required properties to the finished melt. Listed below is a summary of the effects various alloying elements in steel.

Manganese (Mn)Manganese improves hardenability, ductility and wear resistance. Mn eliminates formation of harmful iron sulfides, increasing strength at high temperatures.

Nickel (Ni) : increases strength, impact strength and toughness, impart corrosion resistance in combination with other elements

Chromium (Cr) : improves hardenability, strength and wear resistance, sharply increases corrosion resistance at high concentrations (> 12%).

Tungsten (W) : increases hardness particularly at elevated temperatures due to stable carbides, refines grain size.

Vanadium (V) : increases strength, hardness, creep resistance and impact resistance due to formation of hard vanadium carbides, limits grain size.

Molybdenum (Mo) :
increases hardenability and strength particularly at high temperatures and under dynamic conditions

Silicon (Si) :
improves strength, elasticity, acid resistance and promotes large grain sizes, which cause increasing magnetic permeability

Titanium (Ti) :
improves strength and corrosion resistance, limits austenite grain size.

Cobalt (Co) :
improves strength at high temperatures and magnetic permeability.

Zirconium (Zr) :
increases strength and limits grain sizes.

Boron (B) :
highly effective hardenability agent, improves deformability and machinability.

Copper (Cu) :
improves corrosion resistance.

Aluminum (Al) :
ideoxidizer, limits austenite grains growth.

Brass : Brass is an alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties
It is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, doorknobs, ammunition casings and valves; for plumbing and electrical applications; .

Lead : Lead is a soft and malleable metal, which is regarded as a heavy metal and poor metal. Metallic lead has a bluish-white color. Lead is used in building construction, lead-acid batteries, bullets and shot, weights, as part of solders, pewters, fusible alloys, and as a radiation shield.
