Grade 8625 The most innovative and reliable solution for stainless steel turning

NEW CVD GRADE FOR M25 APPLICATIONS


FIRST CHOICE FOR STAINLESS STEEL TURNING M25 applications are the most important stainless steel turning area. It means different parts, sizes, materials and machining conditions. It is both a roughing and semi-finishing area, very critical for all market segments. Safety has developped the new 8625 grade to meet this industrial demand with the higher productivity and reliability. A good balance of toughness and wear resistance makes this new grade matching high speed machining whatever the conditions. 8625 is based on both a new coating technology and a new substrate recently developped for this area. Our 8625 grade will be the RIGHT SOLUTION for your further success!

FEATURES AND ADVANTAGES ❯ RELIABLE SUBSTRATE: The substrate has increased resistance to plastic deformation at high temperatures and whatever the conditions: semi-finishing, roughing, continuous and intermittent cutting. ❯ OPTIMIZED CVD COATING: New multilayers CVD coating to improve notch wear, flaking and build-up edge resistance which are the main wear mechanism in stainless steel turning. ❯ COMPLEMENTARY AREA: 8625 is a second choice to machine low carbon steel, low alloyed steel and exotic alloys (Nickel and Cobalt base).
