Drawn wires for phosphate-free cold stamping: 0.0% Phosphate
SEBIR TSF© (Phosphate Free Wire Drawing) is a new technology developed by SEBIR for cold deformation without added phosphates.
This product:
Reduces industrial and environmental costs
Offers better performances than phosphated wire
Why SEBIR TSF©? A further step towards sustainable industry
SEBIR TSF© reduces the friction coefficient in stamping, keeping the lubricant on the wire during all stamping phases.
WHAT’S THE SECRET?
Wire drawn at high pressure allows the manufacture of cold formed parts without the use of phosphate, with all the advantages this entails.
Ecological advantages of SEBIR TSF©
LOWER ENVIRONMENTAL IMPACT
- Elimination of phosphate sludge.
- Elimination of waste water contaminated with nitrates and heavy metals.
- Minimisation of contaminated oils.
- Reduction of polluting discharges and waste by 98%.
Functional advantages of SEBIR TSF©
- Improvement of the geometry of the stamped parts.
- Increased deformation capacity.
- Minimises the appearance of cracks at 45 °C and the severity of steel cracks at 90 °C.
- Elimination of the risk of the appearance of the delta ferrite phase in the quenched and tempered bolts.
- Different lubricants adapted to the needs of our customers.
- Reduction of the friction coefficient: very low values of μ=0.12, compared to wires with conventional technology (μ=0.40).
- Behaviour of the friction coefficient in stamping.
Two types of SEBIR TSF©
SEBIR TSF© 1
- Completely eliminates phosphate and other surface coatings.
- Facilitates the deformation of complex parts up to Ø 6.5 mm.
- Reduces CO2 equivalent emissions by 83.4 kg / Ton of TSF wire.
- Avoids the formation of delta ferrite during our customers' heat treatment processes (quenching and tempering) and eliminates the need for phosphating in our facilities.
SEBIR TSF© 2
- Completely eliminates phosphate by means of a mineral-based surface coating, which is completely soluble in cleaning processes.
- Allows complex parts up to Ø 34 mm to be deformed.
- Reduces CO2 equivalent by 48.4 kg / Ton of TSF wire.
- Avoids the formation of delta ferrite during our customers’ heat treatment processes (quenching and tempering) and eliminates the need for phosphating in the installations.
