Stainless Steel / 430-F ANN

430F stainless steel is a ferritic alloy and is identical to 430 stainless, but with increased sulfur to dramatically improve machinability. This alloy does not form as easily as standard 430 due to the sulfur but still has moderate ductility. 430F is often used as gears, fasteners, or solenoids within various industries. (UNS S43020)
