Critical Temperature:

Ac1: 1540°F
PREHEATING
1500-1550°F, equalize.
AUSTENITIZING (HIGH HEAT)
Heat rapidly from the preheat, typically by transferring to a second furnace.
For Optimum Wear Resistance:
Soak for 5 to 15 minutes.
Furnace or Salt Bath: 2150°F
For Balance of Wear Resistance and Toughness:
Soak for 15 to 30 minutes.
Furnace or Salt Bath: 2050°F
For Maximum Toughness and minimum distortion in cooling:
Soak for 30 to 60 minutes.
Furnace: 1975°F
Salt Bath: 1950°F
QUENCHING
Sections less than 3” thick may be air cooled to maximum hardness. Sections 3” thick or more must be quenched at a faster rate, using one of the methods below, to attain maximum hardness.
For pressurized gas, the furnace should have a minimum quench pressure of 4 bars. The quench rate to below 1000°F is critical to obtain the desired properties.
For oil, quench until black, about 900°F then cool in still air to 150-125°F.
For salt maintained at 1000-1100°F equalize in the salt, then cool in still air to 150-125°F.
TEMPERING
Temper immediately after quenching.
The typical tempering range is 1000-1100°F. Do not temper below 1000°F. Hold at temperature for 2 hours then air cool to ambient temperature. Double tempering is required. Triple tempering is required when austenitized at 2100°F.
ANNEALING
Annealing must be performed after hot working and before rehardening.
Heat at a rate not exceeding 400°F per hour to 1600-1650°F, and hold at temperature for 1 hour per inch of maximum thickness; 2 hours minimum. Then cool slowly with the furnace at a rate not exceeding 30°F per hour to 1000°F. Continue cooling to ambient temperature in the furnace or in air. The resultant hardness should be a maximum of 277 HBW.

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 bulldozersoffice 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.
Typical Mechanical Properties
Related Terms of steels
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 steellow alloy steelreinforced 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.
