steel - Effects of heat-treating | Britannica
steel - steel - Effects of heat-treating: Adjusting the carbon content is the simplest way to change the mechanical properties of steel. Additional changes are made possible by heat-treatingfor instance, by accelerating the rate of cooling through the austenite-to-ferrite transformation point, shown by the P-S-K line in the figure. (This transformation is also called the Ar1 transformation carbon steel reducing elbow Heat treatmentWhy are reducing ASTM A234 WPB reducer elbows so called?The reducing ASTM A234 Elbow is so called because it looks like a reducing piece and elbow combined into one unique piece.

The oxidation of steel is caused by the presence of oxygen, carbon dioxide and/or water vapor. The oxidation may manifest itself in a range from a tight, adherent straw-colored film that forms at a temperature of about 180°C (lower temperatures) to a loose, blue-black oxidSee more on forgemag carbon steel reducing elbow Heat treatment

After you harden a metal, whether its by the case or flame, and introduce internal stresses after the rapid cooling inherent in the process, steel is often both harder than needed and too brittle. The answer may be to temper the steel to reduce that brittleness and remove or relieve the internal stresses.THERMAL PROCESS INFORMATION BOOKThe atmosphere provides a dry, carbon-free source of reducing gas. Uses include bright copper and silver brazing, bright heat treating of carbon steels and selected nickel and copper alloys, and bright annealing of electrical components. Dissociated am-monia is also used as a carrier gas in certain nitriding processes. dry hydrogen atmospheres. Commercially available hydrogen is 98

The carbon is removed from the surface layers while the iron does riot get oxidised. Thus, there is a thickness from the surface towards interior, in which, the carbon content is less than the original carbon content of the steel.

Plain carbon steels typically contain 1 percent or less carbon in combination with iron. The maximum hardness that any plain carbon steel can achieve during heat treatment is primarily a function of its carbon content.
Fundamentals of the Heat Treating of Steel
carbon steel and low-alloy steel, the maximum carbon is about 2.0%; in high-alloy steel, about 2.5%. The dividing line between low-alloy and high-alloy steels is generally regarded as being at about 5% metallic al-loying elements (Ref 1).
