Material PropertiesTool SelectionRunning Parametersin ConclusionStainless steels are high-alloy steels with superior corrosion resistance to carbon and low-alloy steels.This is largely due to their high chromium content,with most grades of stainless steel alloys containing at least 10% of the element.Stainless steel can be broken out into one of five categories Austenitic,Ferritic,Martensitic,Precipitation Hardened (PH),and Duplex.In each category,there is one basic,general purpose alloy.From there,small changes in composition are made to the base in order to create specifiSee more on harveyperformance420 Machining 420 Machined Parts Penta PrecisionStainless 420 Machinability.Stainless 420 machines best in the hardened and tempered condition R or condition S.It is similar to machining high carbon tool steels in that it gives tough,stringy chips.There is a free-machining type of 420 but this does come at the expense of other properties.Finishing Treatments.Stainless 420 is usually Some results are removed in response to a notice of local law requirement.For more information,please see here.12345NextStainless Steel - 410 Stainless Steel - BEARTECH ALLOYSType 410 has fair machinability.It has somewhat better machining characteristics than austenitic stainless steels,having a rating of about 55% compared to Bessemer screw stock (AISI B 1112).Sulfurized cutting oils are used for most operations.Weldability
