Aerospace High-Temperature Machining Guide

The main challenges to machining superalloys include: The high strength of nickel-base superalloys at cutting temperatures causes high cutting forces, generates more heat at the tool tip (compared to alloy steel machining), and limits their speed capability. The low thermal conductivity of these alloys

    Machinability Ratings Chart & Data for Expansion Alloys

    Machinability. Typically low expansion alloys machine similar to, but not as good as a Type 316 austenitic stainless steel; or, around 25 percent as good as AISI B1112.They develop somewhat gummier and stringy chips and higher forces, but do not work harden as rapidly as Type 316.Work hardened bars can result in some improvement of the inherent machinability in some instances. Machinability of Heat-Resistance Superalloys (HRSA Machinability of Heat-Resistance Superalloys (HRSA) HRSA is the most challenging material group in machining, and also the most expensive metals to purchase. Although not as popular in machine shops as steel or aluminum, due to the high material and manufacturing cost, its an important niche to master. The machinability ranges from 5% to 40%.

    The machinability rating is determined by measuring the weighed averages of the normal cutting speed, surface finish, and tool life for each material. Machinability rating less than 100% is more difficult to machine than B1112 and material with a value more than 100% is easier. Alloy. UNS.

    Machinability of low-alloyed steels depends on the alloy content and heat treatment (hardness). For all materials in the group, the most common wear mechanisms are crater and flank wear. Hardened materials produce greater heat in the cutting zone and can result in plastic deformation of the cutting edge.
