Carbide Inserts for Turning CVD Coated Grade PC25 (P25–K20 + new CVD Coating based on Al2O3) 1st choice for General Machining of Steel, Stainless & Cast Iron
Geometry MPN for finishing to moderate interrupted cuts, feed range for Steel & Cast Iron = 0.20-0.45, Stainless Steel = 0.20-0.25
Cutting speed [m/min]
Non Alloyed Steel Annealed (<0.15 C 125HB) = 190-290, Annealed (<0.15-0.45 C 150-250HB) = 170-240, Tempered (>0.45 C 300HB) = 130-200
Low Alloyed Steel Annealed (180HB) = 170-250, Tempered (250-300HB) = 100-190, Tempered (350HB) = 80-170
High Alloyed Steel Annealed (200HB) = 130-210, Tempered (350HB) = 80-160
Stainless Steel Annealed Ferritic / Martensitic (200HB) = 130-220, Tempered Martensitic (325HB) = 100-190
Stainless Steel Quenched Annealed (160HB) = 100-210, Hardened Martensitic / Austenitic (350HB) = 70-100
Grey Cast Iron Pearlitic / Ferritic (160HB) = 130-210, Pearlitic Martensitic (260HB) 120-200
Spheroidal Cast Iron Ferritic (160HB) = 120-240, Pearlitic 120-200
Malleable Cast Iron Ferritic (130HB) = 150-250, Pearlitic (230HB) 120-200
