SAE 4320 round bar chemical composition and mechanical properties
Explore a large number of high-quality 4320 low alloy steel hex bar suppliers and exporters in the Middle East
Alloy Steel 4320 Rectangular Bar is used in some of its primary applications in shafts, gears, bearing caps, planetary gears, sprockets, columns, crowns, sleeves, and cylinders. It is utilized in mechanical components where systems demand a homogeneous hardness throughout large or small cross-sections. Its difficulties are less severe than steel, with a carbon concentration of 00:40%.
Due to the low carbon concentration, carburizing can be used to increase wear resistance. 4320 Alloy Steel Round Bar combines medium strength and fracture resistance with ordinary hardenability.

What is the difference between SAE 4320 hex bar hardening and tempering conditions?
SAE 4320 Alloy Steel Cold Drawn Round Bars are hardened and tempered steels to provide components with the mechanical qualities necessary for their intended service. SAE 4320 Hex Bar is heated to the proper hardening temperature, typically between 800-900°C, maintained at that temperature, and then “quenched” (rapidly cooled), frequently in oil or water. This is followed by tempering, which develops the final mechanical qualities and releases stresses during a soak at a lower temperature.

What is peeled and reeled alloy steel UNS G43200 square bar?
Peeling is the removal of a bar’s outer surface with a rotating tool. Surface flaws are more profound and related to the bars’ diameter; these flaws are removed via peeling, where a cut is made as needed. There are two sorts of bright bars: cold drawn and peeled. The Hot Rolled Bars in a Cold Drawn Bright Bar are pickled and drawn through a Tungsten Carbide Die as Cold Rolled; heating is unnecessary. Hence the name Cold Drawn Bright Bar
Second, to produce Alloy Steel UNS G43200 Square Bar, Hot Rolled Bar is passed into a turning machine where the surface is turned or removed to the desired diameter. There is no need for heating in this cold technique. For specific purposes, Bright Bars can be further ground and finished.
There are several different sizes and forms of AISI 4320 steel bar, including hex, flat, square, and rectangular
