New PVD coated grade for machining hard, high temperature alloys
ISCAR is introducing IC804 (ISO S05), a new complementary SUMO TEC PVD coated grade for machining Ni super based alloys and uncoated grade IC4 for machining titan
ISCAR is launching grade IC804 and also extending the selection of uncoated IC4 items. Ni based and titanium alloys used in newly designed jet engine parts feature very high hardness (40-47 HRC) – the future’s trend to additional high hardness parts. IC804 and IC4 provide substantial improvement regarding tool life and cutting speeds for these new materials and also provide advantages in more conventional Ni based and titanium alloys at stable machining conditions.
IC804 features a hard submicron substrate, IC4 with AlTiN PVD coating and a special post-coating treatment that provides substantially improved tool life and high reliability.
Additional uncoated IC4 standard items for machining titanium alloys and aluminum alloys with high silicon content (IC4 is a harder uncoated grade than IC20). Both IC4 and IC804 feature high hardness, especially suited for hard nickel base and titanium alloys.
Features
- High hardness
- High flaking and chipping resistance
- Reliable and repeatable results
- Continuous turning of nickel base super alloys at stable conditions
Super Alloys
Super alloys are commonly used in parts of gas turbine engines that are subject to high temperatures and require high strength, excellent high temperature creep resistance, fatigue life, phase stability, and oxidation and corrosion resistance. Super alloys develop high temperature strength through solid solution strengthening. This is the reason they are so difficult to machine.
