Lubricant additives benefit SS tube
drawing
Work to significantly enhance the lubrication of highly chlorinated tube drawing lubricants - and deep drawing - has lead to the discovery of additives which offer considerable performance benefits.
For 30 or more years seamless stainless steel tube has been produced with the help of chlorinated lubricants These chlorinated lubricants have changed little in this time, and they still perform much the same as they did when first produced

Lubricants smooth severe cold metal reductions
A range of lubricants can be applied as a coating for the most severe cold reductions in stainless steel alloy, and titanium and are suitable for the most arduous operations.
Degreasing solvents outperform trichloroethylene
Degreasing solvents offer overall enhanced solvency compared to trichloroethylene and can be used to effectively remove chlorinated lubricants, lubricating oils, gear oils and maintenance oils.
They are based on a combination of about 90% chlorinated paraffin, and small amounts of fat/oil.
There high performance is limited and this limit to their performance for arduous applications leads some manufacturers requiring heavy reductions to pre-coat their tubing to obtain sufficient lubrication.
This additional process reduces the efficiency of the factory.
The alternative is to have more draws, but this again is very inefficient.
John Neale has worked on ways to significantly enhance the lubrication of highly chlorinated tube drawing lubricants for the last three years.
This work in collaboration with a number of end users has lead to the discovery of additives which offer considerable performance benefits.
These additives work synergistically with the chlorinated paraffin giving advances in performance which were not considered possible.
A manufacturer of stainless steel bicycle tubes was using a chlorinated tube lubricant with typical 90% chlorinated paraffin.
The company was having problems with very high temperatures, fuming and pick up during the drawing process.
This company tried Superdraw ST500P based on the new synergistic chemistry and immediately gained a massive reduction in temperature, no fuming and no pick-up.
A manufacturer of stainless steel tube, who required a combination of dry film coating and traditional high viscosity chlorinated lubricant has proven that Superdraw ST4000P based on the new synergistic chemistry can allow for the drawing of tube without the requirement for the coating to be applied.
This indicates the level of performance benefit that can be obtained.
This new technology can be applied to deep drawing of components.
A company in Scotland deep drawing stainless steel (304) components was having trouble in production, although using a 90% chlorinated paraffin deep drawing lubricant.
Batch to batch variability in the stainless steel sheet was leading to poor tool-life and component quality for some batches of material.
The use of Superdraw ST200P overcame all these production issues and tool-life which was a major problem has become almost indefinite.
