Tool Steels
Tool steels are high quality steels made to controlled chemical composition and processed to develop properties useful for working and shaping of other materials.The carbon content in tool steel may range from as low as 0.1% to as high as more than 1.6%. They are alloyed with elements such as Chromium, Molybdenum,Vanadium Tungsten etc.
At Sunflag Tool Steels are produced through specially designed steel making process via Electric Arc Furnace followed by Ladle Refining and Vacuum Degassing and processed through ESR / VAR for ensuring homogeneous properties &Ultra clean material. Stringent control is practiced during designing of chemical composition and other process parameters during casting, rolling/forging and heattreatment.
Sunflag R&D Lab Is Equipped With Following State Of The Art Equipment:
- Water-hardening tool steel(e.g. cold heading, cutting tools, knives, reamers and cutlery etc)
- Shock-resisting tool steel (e.g. chisel for hot and cold cutting, chuckiaws, gripper, cold shear, hot shear etc.)
- Cold work tool steel [3 types]:
- Oil hardening cold worktool steel(thread cutting, die blanking, cold-forming, cold trimming, gauges etc.)
- Medium alloy air hardening cold work tool steel (blanking, coining, cold forming, cold swaging, cold trimming
tools, gauges etc.) - High carbon, high chromium cold work tool steel(die inserts, cold—forming, cold shaping, thread roll, cold
trimming, wire drawing etc.)
- Low alloy special purpose tool steel(forging dies, die casing, file cutting, paper cutter, die bending, blanking and
coining etc.) - Mold tool steel(plastic mold)
- Hot work tool steel (die casting dies, hot extrusion dies, hot forging dies, hot swaging, hot trimming, hot shear,
hot gripper etc). - High-Speed Steels (Single point cutting tools, broach insert, tap, drill, reamers, milling cutters, saws)
