Stellram’s
New Turning Geometry 4E for unmatched performancein High Temperature Alloys.
ATI Stellram specifically designed the 4E to
meet the demands of machining aerospace type
components, manufactured from High Nickel,
High Cobalt and Titanium-based alloys.
Our Research & Development team worked closely
with production engineers and machinists from within
the aerospace and power generation industries, to
identify their needs for the right product to machine
these ever increasingly difficult to machine materials,
in the most cost effective and efficient way.
The ATI Advantage
Stellram is a business unit of ATI Engineered Products,
an operating company of Allegheny Technologies,
Inc. ATI is a world-leading producer of titanium and
other high temperature heat resistant alloys. The
company’s tooling engineers and metallurgists pool
their talents to achieve smarter solutions for hard to
machine materials. The technology transfer between
the companies provides an extensive knowledge base
of the metals as well as cutting tool performance.
Grade profileGrade SP0819 a new generation in PVD coating:The combination of a micro-grain substrate with a new generation ofTiAlN Nano coating, makes this new PVD coat extremely hard for unmatched performance.
Grade NL40Also available in industry proven NL40, a CVD cobalt enriched grade for more demanding applications, both grades optimize faster cycle times, longer tool life and greater component integrity.

LONGER TOOL LIFEThe combination of a new Super-hard coating with aerospace approved micro-grain carbide substrate has significantly improved heat and wear resistance in high temperature alloy machining, enabling longer tool life and higher productivity.
Substrate andCoat Cross section
4E proven turning solution to aerospace materials:
Tested Against the Best:The 4E was tested against some of the best products in the market place today in the toughest of materials
and consistently proved to out perform the best.
Only one versatilegeometry required:
The 4E has been designed to machine a wide variety
of materials including Stainless Steels, High Nickel,
High Cobalt and Titanium based alloys, thereby
reducing shop inventory, operator error and cost.
Improved component quality, our new precise
reinforced chipbreaker profile with positive cutting
action, dramatically reduces built up edge, leaving
a smooth surface finish and greater component
dimension integrity.
