Material cross-reference

Type any name or number, like 4140, 1.4404, EN-GJS-500 or Inconel 718, to find its equivalents and the ISO group to choose inserts for.

P

Steel

Unalloyed, low-alloy and high-alloy steel, tool steel, cast steel, ferritic and martensitic stainless. Long chips. Generally predictable and the easiest group to machine. Starting Vc with carbide: turning 150–300 m/min, milling 120–250 m/min.

M

Stainless steel

Austenitic, duplex and super-duplex stainless steel. Work-hardens, builds up on the edge and holds heat. Keep the feed up and the edge sharp. Starting Vc with carbide: turning 100–200 m/min, milling 80–180 m/min.

K

Cast iron

Grey, ductile (SG), malleable and compacted graphite (CGI) iron. Short, broken chips. Abrasive, so edge wear is the limit. Starting Vc with carbide: turning 150–300 m/min, milling 120–250 m/min.

N

Non-ferrous

Aluminium and its alloys, copper, brass, bronze, plastics and composites. Soft and gummy. Sharp, positive, polished edges at high speed. Starting Vc with carbide: turning 300–1000 m/min, milling 300–1000 m/min.

S

Superalloys and titanium

Nickel, cobalt and iron-based heat-resistant alloys; titanium and its alloys. Heat stays in the edge. Low speed, notch wear and work hardening. Starting Vc with carbide: turning 30–80 m/min, milling 25–70 m/min.

H

Hardened materials

Hardened steel 45–68 HRC, chilled and white cast iron, hardfacing. CBN, ceramic or fine-grain coated carbide. Rigid set-ups only. Starting Vc with carbide: turning 50–150 m/min, milling 50–120 m/min.

Equivalents marked ≈ are close but not identical in chemistry; check the mill certificate where it matters. * Ferritic and martensitic stainless is often machined with P-grade inserts.
