The machinability of various grades of steel can be improved by an annealing process. The toughness can be increased by normalizing and the strength can be boosted by quenching and tempering.
Soft / Spherodised Annealing operation converts the carbides in the steel to globules – a procedure known as spherodisation. This makes the steel softer and gives it better formability properties. Incompletely spherodised steel increases the risk of sheer fracture, particularly during cold forming. Further, the yield properties of steel are impaired and the tool wear increases. A correctly executed annealing process also gives better machinability. High-strength steel, in particular, make heavy demands on correct annealing to ensure optimum machinability.
We provide soft annealing as well as spherodised annealing for wire rods and coils.
