Case Hardening 1045 [Archive] - The Home Shop Machinist

1045 is medium carbon steel, with .45% carbon. It doesn't need additional carbon to harden it. So carburizing is unnecessary for heat treating 1045. If you want to harden the skin, just heat it with a torch as Brockley recommended, and quench with water.

Carburizing and Case Hardening- Metlab of Wyndmoor PA

Metlab has the ability to carburize and harden gears and other components that are small enough to be held in one's hand, up to 14' in diameter and 16' tall, weighing as much as 50,000 pounds. Shallow cases only 0.002 - 0.005", and deep cases, up to 0.350" have been specified and readily achieved.

Carburizing - Wikipedia

Carburizing, carburising (chiefly British English), or carburization is a heat treatment process in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder.

Carburizing & Carbonitriding | Thermex Metal Treating

Carburizing. Carburizing is a surface hardening treatment that produces a hard, wear-resistant layer (case) on the part surface. Case depth can range from as low as 0.010", to as deep as 0.200". Surface hardness can be as high as 62 - 64 HRC. Gas carburizing is ideal for improving the surface hardness and wear resistance of low carbon mild or low alloy steels (such as 1018, 1026, 8620, 9310).

Heat Treatment of Steel - Zianet

Steel at normal temperatures has its carbon (which is the chief hardening element) in a certain form called pearlite carbon, and if the steel is heated to a certain temperature, a change occurs and the pearlite becomes martensite or hardening carbon. If the steel is allowed to cool slowly, the hardening carbon changes back to pearlite.
