The best treatment ever for tool steels. This is a deep chilling treatment for prolonged period of time, which makes the alloy carbides in steel precipitate leaving very tough matrix of martensite. Increased toughness guarantees resilience to abnormal shocks, while fine precipitates of carbide reduce wear. Experience suggests 100% increase in life of the tool.

Optimal roll alignment for fast rolling. Maximum roll to tube contact reducing spring back effect. Equal load distribution leading to extended expander life
CNC machined cages give Precision guiding to rolls during expansion.
One piece cons truc ted mandrel on all models mates with well contoured rolls to give un-bridged smooth expanded tube.
