Grade Introduction:
Bright Bars is an important type of free cutting steel that has made its way into the market. These are widely used by several industries for the use in the production of the above mentioned instruments and parts. As this type of steel forms chips when it is worked on, they can take up only an average amount of heavy duty items at a time. When they are sold in the market, the grade of the free cutting varies with its composition. Sulphur or phosphorous are the two main types of ingredients that are added to the steel, apart from some little amounts of carbon.
 
EN8M type of free-cutting steel in Bright Bars has Sulphur added to it with a medium amount of carbon. They are mostly round or hexagonal in shape. These bars are used for making shafts, gears, studs, pins and gears.
 
Bright Bars have found usage at a very wide scale, extending quality construction finish, anti-corrosive properties, and high durability.
 
Grade Application:
These bars are used for making shafts, gears, studs, pins and gears.

Heat treatment:
Heat treatment temperatures, including rate of heating, cooling and soaking times will vary due to factors such as the shape and size of each EN8M steel component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities.
 
Hardening:
Heat the component slowly to 820-860°C and allow it to be heated through. Quench in oil or water.
 
Tempering:
Temper the EN8M component immediately after quenching whilst tools are still hand warm. Re-heat the EN8M component to the tempering temperature then soak for one hour per 25 millimeter of total thickness (2 hours minimum) Cool in air. For most applications tempering of EN8M will be between 550-660°C.
