Flame Hardening Steel Grades

Flame hardening is performed on parts made of mild steels alloy steels medium carbon steels and cast iron.

Flame hardening steel grades.

Factors that affect the depth of hardness achievable in steels and relationships between hardness and tensile strength are also outlined. The metals are heated to temperatures to their austenization temperature causing the surface to change while the core remains unchanged and soft. Process of flame hardening 4140 other steel grades of machined parts and stampings. To harden steel start by heating the metal directly with a blow torch until it turns a cherry red color.

Flame hardening sometimes begins with a preheat operation depending on the alloy and degree of machining. Below is an outline of the process that follows thereafter. The component is fixtured to the spin table and torch heads are adjusted to ensure proper. The hardness of steels can be increased using various processes such as surface flame and induction hardening as well as nitriding.

The process of flame hardening. Depending on the amount of time and temperature the affected area can vary in carbon content. Keep a grade b fire extinguisher nearby in case of a fire. As its name suggests flame hardening uses direct heat from oxy gas flames.

Hold the steel directly in the flame. Heat is applied to the part being hardened using an oxy acetylene or similar gas flame on the surface of the steel being hardened and heating the surface above the upper critical temperature before quenching the steel in a spray of water.
