Lord and Midgley buy and sell Ferous Metals.
It Contains about 0.05 to 0.30% carbon and the rest is iron.
It is malleable and ductile, and bends easily.
It is used in the manufacture of nuts, screws, bolts, girders and other general metal products.
► Medium-carbon SteelIt contains about 0.30 to 0.60% carbon.
It is relatively harder and less ductile than low-carbon steel.
It is used in the manufacture of car components like axles, gears and crankshafts.
► High-carbon SteelIt contains 0.60 to 0.99% carbon, and may also contain small amounts of manganese, silicon, and copper.
It is the strongest and hardest of all carbon steels.
It is used to make blades, springs, and high-strength wires.
► Tool SteelAlso known as tool and die steel, it is specifically used for making machine parts, metal cutting tools and dies, as well as molds used for injection molding.
It contains 0.7 to 1.5% carbon, as well as molybdenum, tungsten, vanadium, and other metals.
It is resistant to heat, abrasion, and corrosion, unlike other carbon steels.
Stainless SteelAlso known as corrosion-resistant steel, it is an alloy of iron, nickel, and chromium.
The important property of stainless steel is its high resistance to corrosion owing to the presence of chromium.
It is tough and resistant to stains, hence, called stainless steel.
This steel can be welded, machined and shaped easily depending on the type of steel.
It is commonly used in kitchen cutlery and cookware, axles, desks, nails, medical instruments, kitchen draining boards, pipes, etc.
Cast IronCast iron, another commonly used ferrous metal, is made up of 2.1 to 4% carbon, 1 to 3% silicon, and 89 to 94% iron.
It is strong but brittle, and has a high compressive strength.
It is resistant to oxidation and corrosion.
It can be classified into different varieties like gray cast iron, white cast iron, malleable cast iron, and ductile cast iron.
Cast iron can be bronze-welded or arc-welded, and hardened or machined.
Cast iron is normally used in the manufacture of heavy crushing machinery, machine tool parts, brake drums, car cylinder blocks, machine handles, gear wheels, plumbing material, as well as several household items.
Wrought IronWrought iron has a very low carbon content of 0.10 to 0.25%.
It is strong and tough, yet fibrous and ductile.
It is no longer produced commercially, and has been replaced by mild steel.
It was used to make ornamental gates, farm and garden equipment, railings, nails, wires, etc.
