Alloy Steel is special steel including alloyed with a variety of elements in total amounts of between 1.0% and 50% by weight to improve its mechanical properties from a high heat.

Annealing is the process used to iron, less brittle, performed by allowing them to cool very gradually from a high heat, easy for turning operation.

Carburizing is a process of adding Carbon to the surface. Steel color from this process is white ex. S50C
Elongation is the amount of extension that is measured against 2 metals.

Flame-hardening Steel is the process of heat treatment involves heating the steel and then cooling it. The steel is hardened and yet malleable enough that it can still be worked.

Hardness is the resistance of a material to localized deformation.

Heat Treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape.

Hot Rolled Steel is the steel from hot-rolled process directly, therefore; turning process is harder than the steel from Normalizing and Annealing.

Induction is the controlled heating through high electric current 900c. The depth depends on the heat on wire.

Nitriding is a heat treating process that alloys nitrogen onto the surface of a metal to create a case hardened surface.

Normalizing is a type of heat treatment applicable to ferrous metals only, easy for turning operation.

Pre-hardened Steel is steel made by precise heat treatment, can be used as a mandrel drawing tube to make a tube.

Press Die is a perforated block of hardened steel used to press through plates.

Punching Die is a perforated block of hardened steel used to punch through plates.

Rough Turned Steel is steel finished from turning operation.

Strength is the quality or state of being strong.

Stress Relieve is the heat treatment applied.

Toughness is the ability of a metal to deform plastically and to absorb energy in the process before fracture.

Vacuum Heat Treatment is one of the most prospective methods for heat treatment of tool steels to improve their operational characteristics including Oil quenching and Gas quenching.

Wear Resistance is the ability to resist wear on the surface.
