ASTM A582 Free Machining Stainless Steel Round Bars 303 416 420F 430F
We produce Free machining Stainless steel bars as per ASTM A582 / A582M Standard
Specification for Free-Machining Stainless Steel Bars.
303 is the most common “free-machining” grade using sulphur to produce sulphides allowing easier
chip-breaking during machining.
Applications: Threaded fasteners, shafts, valve bodies, precision measurement devices, pneumatic manifolds.
430F is used where a high level of magnetic permeability is required.
This derives from its fully ferritic structure. Its high level of machinability allows volume throughput of components.
Applications: Magnetic cores, solenoid valves, relays, fuel injection systems, anti-lock braking systems,
electromagnetic pumps.
416 is the most common “free-machining” martensitic grade using sulphur to produce sulphides allowing easier
chip-breaking during machining.
Applications: Shafts, axles, gears, valves, fasteners, golf club heads, sensors, precision machined
components, gun barrels, washing machine parts, dowel pins, clamps, collars.
Type 420F, a free-machining version of Type 420, is a hardenable 12% chrome steel with
higher strength, hardness, and wear resistance than Type 410.
