WHAT IS CARBURISING
Carburising is a thermochemical process in which carbon is diffused into the surface of low carbon steels to increase the carbon content to sufficient levels so that the surface will…
What Is Case Hardening
Case hardening is a technique in which the metal surface is reinforced by the adding of a fine layer at the top of another metal alloy that is generally more…
Martempering/Marquenching
Marquenching/Martempering is a form of heat treatment applied as an interrupted quench of steels typically in a molten salt bath at a temperature right above the martensite start temperature. The…
Austempering
Austempering is a heat treating process for medium-to-high carbon ferrous metals which produces a metallurgical structure called bainite. It is used to increase strength, toughness, and reduce distortion. Parts are…
Jominy End Quench Test of Hardenability
“This is a classic test to evaluate how heat treatments affect steel properties” Steel can be very hard or very soft, depending largely on the heating and cooling it is…
Hardenability
A measure of how easy it is to fully harden a steel is known as its hardenability. The higher the hardenability, the easier it is to harden and the slower…
Tempering
Tempering is a low temperature (below A1) heat treatment process normally performed after neutral hardening, double hardening, atmospheric carburising, carbonitriding or induction hardening in order to reach a desired hardness/toughness…
Normalising
Normalising aims to give the steel a uniform and fine-grained structure. The process is used to obtain a predictable microstructure and an assurance of the steel’s mechanical properties. Benefits After…
Spheroidizing
Spheroidizing refers to a heat treatment material modification process that is used to convert granular structures of the material into a spheroidal form. The process is performed to improve a…
PLASTERING
Applying mortar coats on the surfaces of walls, columns, ceiling etc. to get smooth finish is termed as plastering. Mortar used for plastering may be lime mortar, cement mortar or…
