The function of chemical carbon &Forged in steel fittings make stronger?
While the addition of carbon can provide greater toughness and yield strength,
the carbon content of the steel itself is not always equal to the strength of the alloy. Carbon alloys will make steel more difficult to harden – the ability and ease with which alloy steel can be hardened – usually by heat treatment or rate cooling.
The role of carbon as an interstitial that inhibits dislocation movement in the steel matrix is a strength factor, but the most basic and powerful effect of carbon with iron atoms is that it can produce martensite, a hard, brittle phase that form when carbon is ‘trapped’ in an iron crystal lattice. Carbon steel undergoes a change in phase and crystal structure (the way atoms stack up) with temperature. At temperatures above ~1500F or ~800C, the steel is ‘Austenitic’ and has a Face Centered Cubic (FCC) structure. Under this temperature, it transforms into ‘Ferrite’, which has a Body Centered Cubic (BCC) structure. When carbon is between these Fe atoms during a phase change, the Fe atoms will try to rearrange themselves from FCC to BCC, and the carbon will diffuse and form Fe3C, or Cementite. When rapidly cooled (water cooled, or even water cooled for some high carbon steels), the carbon does not have enough time to diffuse to form Cementite, and Martensite, a Body Centered Tetragonal (BCT) structure forms. of Ferrite which has 0.2% carbon by weight and is really very soft.
Martensite is very brittle because BCT is essentially a truncated state of BCC and can exhibit a lot of stress in its crystal structure. very good in important
Carbon steel forgings are often used in the manufacture of heavy machinery such as bridges, ships and railway cars. They have a good combination of strength, stiffness and ductility, which makes them suitable for large-scale production. Carbon steel forging is also used to fabricate auto parts (such as engines), machine tools, aircraft frames and so on.
- Carbon steel forging is a process in which the metal is heated, cooled and then quenched to produce a final shape.
- It is an alloy that has a high carbon content, which makes it easier to work with than other types of steel.
- Carbon steel is often used for construction purposes because it can withstand high amounts of pressure without breaking down or cracking.
- Carbon steel forging can be done manually or by machine depending on the needs of the customer and the type of work being done.
- The introduction of modern technology has made it possible to produce high-quality products with low cost and short development cycle time.
