What is the chemical composition of metal en-45?
en 45 is a silicon mangenese spring steel, supplied in the as rolled contition. This steel is suitable for oil hardening and tempering.
What is tempering of steel?
molding
What is the purpose of tempering a quench hardened plain carbon steel?
Tempering is applied to quench hardened plain carbon steel to: 1. reduce brittleness. 2. increase ductility. 3. increase toughness. 4. relieve stresses in the martensite structure. Increase in tempering temperature lowers the hardness. The reduction in hardness of the quenched steel depends upon the composition of the alloy and the exact value of the temperature applied.
Is high carbon steel stronger than tempered steel?
Tempered steel is not a classification of steel. It is a term used to indicate that the steel has undergone proper heat treatment in which case..yes, the steel that has been properly hardened and tempered would be stronger. This answer assumes that the high carbon steel is in its annealed state and has not received heat treatment and tempering of its own.
Does tempering make copper stronger and more malleable?
Tempering does not make copper stronger, as it is a process typically used with steel to improve its toughness and ductility. Copper can be strengthened through work hardening or alloying with other metals. Tempering copper is not a common practice due to its intrinsic properties.
Why do you heat treat?
You heat treat to improve the molecular structure of the steel. In the untreated state steel is very soft and is relatively easy to bend but when hardened the steel become very hard and brittle. The steel is so brittle after hardening that if say dropped on a concrete floor it may shatter. Tempering relieves some of this stress and makes the steel hard but not too hard.
Does Diffusion help hardening of steel?
yes

Difference between air hardening and stainless steel?
There isn't really a difference since a piece of steel can both stainless and air hardened. Stainless steel is a steel alloy with a minimum of 10% chromium content by mass. Metals can be hardened in a variety of ways. They may be work hardened, tempered, air or oil hardened, for example. Tempering, or the systematic heating, cooling and reheating of a material is one technique that might be used to harden steel.
What is case hardening?
Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy.
What is toughening process in steel?
Toughening is a process in steel in which the material is reheated to a specific temperature, then cooled slowly in order to increase its ductility and reduce its hardness. This helps to make the steel less brittle and more resistant to fractures or cracks under stress.
