Overview & Features
430F stainless steel is a type of non-hardenable Ferritic stainless steel, a free-machining version of 430. With increased sulfur (0.15% at minimum), 430F exhibits remarkably enhanced machinability, but it at the same time can incur hot cracking when welded. Though 430F stainless steel and 430 have the same chromium content (16%~18%), the increased sulfur content decreases its corrosion resistance. 430F is available in stainless steel round bars & stainless steel hex bars, commonly supplied at annealed condition.
Features of 430F Ferritic Stainless Steel
430F stainless steel features excellent machinability with appropriate corrosion resistance. Due to the high sulfur content, 430F are not readily formable as 430, nor hardenable through heat treatment. 430F has moderate ductility and can withstand moderately low cold forming. Exposure to temperatures up to 370 ºC~525 ºC can increase its embrittlement. Its melting point is 1482 ºC. Grade 430F is not suggested to be welded. Filler materials are necessary when such scenarios arise. Post-weld annealing can restore the ductility in the heat affected zones. 430F are considered when machining work is required, especially suitable for screw machines.
Density (at 20 ºC): 7.78 g/cm3
