The Difference between Stainless Steel VS Steel

Stainless Steels will always machine slower than steel but what you lose in machinability you gain in durability Below you will find a list of the different types of stainless steels that we specialize in Remember that stainless steels have different amounts of chromium added to them in order to resist rust but that this makes them generally less tough than regular steel.
