Use of steel
Iron and steel are used
widely in the construction of roads, railways, other infrastructure,
appliances, and buildings. Most large modern structures, such as stadiums and skyscrapers, bridges, and airports, are supported by a steel skeleton.
Even those with a concrete structure employ steel for reinforcing. In addition,
it sees widespread use in major appliances and cars.
Despite growth in usage of aluminium, it is still the main material for
car bodies. Steel is used in a variety of other construction materials,
such as bolts, nails, and screws.
Other common applications
include shipbuilding, pipeline transport, mining, offshore construction, aerospace, white goods (e.g. washing machines), heavy equipment such as bulldozers, office furniture, steel wool, tools,
and armour in the
form of personal vests or vehicle armour (better known as rolled
homogeneous armour in
this role). Steel was the metal of choice for sculptor Jim Gary and
a frequent choice for sculpture by
many other modern sculptors.

Usage of Steel.
Firstly, The structuralsteel，
1>The construction and engineering with the structural steel is called construction steel, it is used in building, bridges, ships, boilers or other engineering, it is the production of the metal structure of the steel. Such as carbon steel, low alloy steel, reinforced steel.
2> Machinery manufacturing structural steel- steel structural parts for manufacturing machinery and equipment. For his style of steel, it is basically a high-quality steel or high-quality steel, mainly has quality carbon structural steel, alloy structural steel, easy to cut structural steel, spring steel, bearing steel, etc.

Generally used in the manufacture of a
variety of tools, such as carbon tool steel, alloy tool steel, high speed tool
steel, etc. According to the usage, it can be divided into cutting tool steel,
die steel, gauge steel.
Steel with special properties, such as
acid-resistant stainless steel, heat cannot afford leather steel, high
resistance alloy steel, wear-resistant
steel, magnet steel, etc.
This means the steel professional use of
the various industrial sectors, such as automotive steel, farm machinery steel,
aviation and steel, chemical machinery steel, boiler steel, electrical steel,
welding rod steel.
(1)Ordinary steel, more elements containing
impurities in the steel, P≤ O.05%,S≤ 0.045%,such as carbon steel, low-alloy structural steel, etc.
(2)Quality steel, less elements containing
impurities in the steel 0.04%,S≤ 0.04%, such as high-quality carbon structural steel, alloy
structural steel, carbon tool steel and alloy tool steel, spring steel ,
bearing steel ,etc.
(3) High quality steel, fewer elements
containing impurities in the steel ,S≤ O.03%,P ≤ 0.035%,
such as alloy structural steel and tool steel. High quality steel behind the
steel grade, it is usually added the symbol "A" or the Chinese
character "high" in order to be recognized.
Delivery Status of steel,
1. Hot rolled,2cold drawn (rolled),3normalizing,4annealed,5high-temperature tempering,6solution treatment.
