Metal Classification Of Flat Steel Bar

Flat Steel Bar, refers to the width of 12-300mm, thickness 3-60mm, rectangular cross-section and slightly blunt side of the steel. Flat Steel Bar can be finished steel, can also be welded pipe blanks and thin rolled sheet thin plate. The main purpose: Flat Steel Bar as a useful material can be used for hoop iron, tools and mechanical parts, construction for the frame structure, escalators.

Metal according to the structure can be divided into: ferrous metals, steel and non-ferrous metals

Flat Steel Before introducing the classification of steel, please briefly introduce the basic concepts of ferrous metals, steel and non-ferrous metals.

1, ferrous metal is iron and iron alloy. Such as steel, pig iron, iron alloy, cast iron and so on. Steel and pig iron are based on iron, carbon as the main element of the alloy, collectively referred to as iron-carbon alloy.

① pig iron is the iron ore into the blast furnace smelting from the product, mainly used for steel and manufacturing castings.

② the cast pig iron in the melting furnace melting, that is, cast iron (liquid), the cast iron cast into castings, this cast iron is called cast iron.

Iron alloy is composed of iron and silicon, manganese, chromium, titanium and other elements of the alloy, ferroalloy is one of the raw materials of steel, steel in steel when the steel deoxidizer and alloying elements used.

2, the steel with iron into the steel furnace according to a certain process smelting, that is, steel. Steel products are steel ingots, cast slabs and cast directly into various steel castings. Usually referred to the steel, generally refers to the rolling into a variety of steel steel. Steel is black metal but steel is not exactly equal to ferrous metal.

3, Flat Steel non-ferrous metals, also known as non-ferrous metals, refers to the black metal and other metals and alloys, such as copper, tin, lead, zinc, aluminum and brass, bronze, aluminum alloy and bearing alloys. In addition, the industry also uses chromium, nickel, manganese, molybdenum, cobalt, vanadium, tungsten, titanium, etc. These metals are mainly used as alloy additives to improve the performance of metals, including tungsten, titanium, molybdenum and other Of the cemented carbide. These non-ferrous metals are known as industrial metals, in addition to precious metals: platinum, gold, silver and other rare metals, including radioactive uranium, radium and so on.
