MACHINING EVALUATION OF HIGH-STRENGTH MARAGING STEEL.
Abstract
The machining characteristics of 18% nickel-300,000 psi ultimate tensile strength grade maraging steel were investigated. Tool life was compared with AISI 4340 steel of the same hardness. Turning tests for two different feed rates with different carbide grades and various rake angles were conducted for this evaluation. Tool life for 18% nickel maraging steel is comparable to AISI 4340 HR steel for +5 degrees side rake but is slightly less for -5 degrees side rake angle. The specific power consumption for the maraging steel is lower than for AISI 4340. The greatest difficulty in machining this material can be attributed to its ductility: the chip is difficult to break and a large burr is usually produced. (Author)
