Inconel 718 / Inconel 625

Inconel 718 is a common nickel-based superalloy with the following characteristics:

• High strength

• Good high-temperature performance

• Difficult-to-cut properties

Inconel 625 is also a nickel-based superalloy, one of its main characteristics being:

• Excellent corrosion resistance

Thread Machining Characteristics

Machining Inconel 718 / 625 may produce:

• Long, thin chips

• Tool wear

• Material adhesion

• Thread shrinkage

• Unstable thread quality

Thread machining of these materials should not be limited to general HSS taps. Instead, appropriate tool materials and structures should be selected based on material properties, machining methods, and tool life requirements.
