Stainless Steel Rod, Bar, Wire, Cold drawn, ground and polished
Standard length of bars: 2 - 3 meter.
Austenitic Stainless Steel for implants, with high corrosion resistance.
For surgical instruments, fracture fixation devices, screws for implants and many more similar applications.
Round bar / flat bar / strip / Square bar / forgings
Bright - peeled + polishing, centerless grinding
Forged - ring, tube, pipe casing, discs, shaft
The alloy is usually produced by AOD / VOD /VIM followed by electroslag refining (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied black/bright in the annealed condition.
Final heat treatment - solution treatment / QT
Mechanical parts used in the condition of corrosion resistance.
Bolt and nut.
