Question

list of all metals with grade and chemical composition​

Answer 1

Mu-metal (iron) Permalloy (iron, molybdenum) Supermalloy (molybdenum) Brass (copper, zinc, manganese) Nickel hydride (hydrogen) Stainless steel (chromium, molybdenum, carbon, manganese, sulphur, phosphorus, silicon) Coin silver (nickel).....

Answer 2

Carbon

Carbon is one of the most important chemical elements in steel. An increase in carbon content yields a material with lower ductility and higher strength.

Manganese

Manganese is used as a neutraliser in hot rolling production of steel together with oxygen and sulphur, and it produces effects on the steel grades’ material properties similar to those of carbon.

Chromium

Chromium is present in small amounts and is used in combination with copper and nickel to increase the material’s resistance to corrosion.

Aluminium

Aluminium is one of the most important deoxidisers, and aids in forming a more fine-grained crystalline microstructure.

Copper

Copper is also used to increase resistance to corrosion. It is the main anti-corrosion component of steel grades A242 and A441 (withdrawn, replaced by A572).

Molybdenum

Molybdenum improves the steel’s strength at high temperatures and also increases its resistance to corrosion. For steel grade A514, a common amount of molybdenum ranges between 0.15–0.65%.

Sulphur and phosphorus

Sulphur and phosphorus generally constitute a restricted amount in steel alloys for they have undesirable effects on steel’s durability and strength.

Other alloying elements such as titanium, nitrogen, and boron are also used in small amounts by some steel grades. These chemical elements are combined with the major components to further improve the performance of the materials

Steels can be broadly categorised according to their chemical composition – alloy steel, carbon steel, and stainless steel.
