View Full Version : Semi-steel

Maybe every other chip maker knows this but me (I'm kinda new to machining), but in the machining catalogs I see the term "Semi-steel"... usually describing lathe chucks. What's semi-steel? Is that a cross-breed between cast iron and steel?

Yes. Slightly tougher than cast iron. If you want more info check machinery's Handbook or US Steel's "Making and Shaping of Steel"
