330 stainless steel machinability. 418 greek ascoloy approximate surf. This alloy also possesses great resistance to stress corrosion cracking and sigma phase formation. Rigid mounts sulfurized lubricants positive feeds and slow speeds are recommended for machining grade 330 stainless steel. In the annealed condition it has.

The more difficult machinability compared to austenitics is most noticeable when using carbide tooling. This is illustrated in figure 1with a relative machinability index comparison for some duplex stainless steels and type 316. Incoloy alloy 330 alloy 330 uns n08330 specifications. The american iron and steel institute aisi determined the machinability ratings for a wide variety of materials.
