430F General Information
Where can stainless steel 430F be used?
Stainless steel 430F can be used for bolts, fasteners, screws, shafts, valves, injector parts and kitchen utensils to name just a few. Due to the added Sulphur it can be easily machined, is corrosion resistant and can maintain an aesthetic finish with the correct care.Is AISI 430F a stainless steel?
A classic stainless steel has a mass fraction of at least 10.5% of chromium. The 430F has a mass fraction of 15.5 - 17.5% of chromium and is therefore a stainless steel.Is the AISI 430F corrosion resistant?
Yes, the 430F is corrosion resistant. With a chromium content of at least 10.5% a steel can be classed as corrosion resistant.General corrosion resistance for AISI 430F stainless steel
Due to the added Sulphur 430F has a moderate corrosion resistance, making it difficult to use this steel in environments where pitting or crevice corrosion is an issue.Is the stainless steel 430F magnetizable?
As a ferromagnetic steel the 430F stainless steel is magnetisable which can be advantageous for some applications and is suitable for magnetic clamping.AISI 430F Heat treatment
Annealing AISI 430F
To anneal stainless steel 430F, heat the material to a temperature of 1382 - 1562°F (750 - 850°C) and finish this process by cooling parts down in the furnace or in air.
Hardening stainless steel 430F
Heat the workpieces uniformly to a temperature of 1742 - 1958°F (950 - 1070°C) and quench them after.Quenching stainless steel 430F
The 430F stainless tel can be quenched in the following media:• Air
• Oil
• Compressed gas (N2)
Tempering stainless steel AISI 430F
Heat the parts uniformly to temperature of 1022 - 1202°F (550 - 650°C) and cool in air. The temperature for the tempering process depends on the desired strength.
Dimensional changes for stainless steel 430F
The 430F can undergo dimensional changes during heat treatment, phase changes, machining and internal stresses. Overheating, uneven heating or cooling should be avoided and controlled heating and cooling as well as proper machining with sharp tools, coolant and feed can prevent heat build up and thermal shock.
Electrical Discharge Machining (EDM) of stainless steel 430F
EDM is used for parts made from one individual piece, for cutting dies or when making intricate shapes. There are various methods to erode various materials, some of them are for example wire erosion, spark erosion or die sink erosion. When using EDM for the 430F care should be taken to minimize heat affected zones and use the correct parameters to remove material.Surface treatment for stainless steel 430F
Passivation of stainless steel 430F
Passivation will remove free iron from the surface using nitric and citric solutions and enhance the natural corrosion resistance of the steel.Physical Vapor Deposition/Chemical Vapor Deposition of AISI 430F
PVD and CVP are processes overlaying the surface of the 430F with a thin film to enhance wear resistance or reduce friction.Bead blasting stainless steel 430F
Abrasive particles like glass or ceramic beads are blasted against the surface to remove contaminants like rust, paint or scale and to promote a uniform matt finish.Note: Care has to be taken during this process as the process produces dust and small parts might be propelled back. Protective gear like masks, helmets and protective clothing should be worn and adequate ventilation or dust extraction should be provided.
Pickling stainless steel 430F
Care has to be taken with this process as the 430F contains Sulphur to improve the machinability of the material. Pickling is a chemical treatment using strong acids so care has to be taken to avoid excessive surface etching and pitting.Machinability for stainless steel 430F
With the addition of Sulphur this stainless steel has a better machinability in comparison to other 12 and 17% chromium steels.Forging stainless steel 430F
Preheat the parts uniformly to the temperature of 1500 - 1600°F (816 - 871°C) and then as rapidly as possible to the forging temperature of 1472 - 2012°F (800 - 1100°C). Do not let the temperature drop below 1500°F (816°C) while forging and do not soak at the forging temperature as it can result in grain build up. To finish this process let the forgings air cool and anneal them after.Welding stainless steel 430F
Generally welding this steel grade is not done due to the added Sulphur content. Should welding be necessary though, preheat the material to a temperature of 302 - 392°F (150 - 200°C). Embrittlement in the weld metal and in the heat-affected zone can be reduced by subsequent post annealing the parts at a temperature of 1454 - 1499°F (790 - 815 °C), but no microstructural refinement will take place. Choose fillers and electrodes according to the applications of the parts.Wear resistance for 430F stainless steel
The wear resistance for the 430F is a t 3 on a scale where 1 is low and 6 is high.430F stainless steel tensile strength
The tensile strength for the stainless steel 430F is approx. 124.7 KSI (0.145KSI = 1MPa). This value is the result from a tensile test to show how much force is needed before the material starts to stretch or elongate before it breaks.Working hardness for stainless steel 430F
The working hardness for the 430F stainless is approx. 255 BHN (26 HRC) (delivery condition).Specific heat capacity of 430F stainless steel
The specific heat capacity of the 420 FM tool steel at room temperature is at 0.46 J/g-°C (0.109 BTU/lb-°F). This value shows how much heat is needed to heat 1lb of material by 1 Fahrenheit.Continuous TTT-diagram for AISI 430F stainless steel

Modulus of elasticity (Young’s Modulus) of 430F stainless steel
The stress and strain modulus or modulus of elasticity (Young’s modulus) for 420 mod. stainless steel is at 31.183 KSI (215 GPa).Is stainless steel 430F a knife steel?
The 430F can be used as a knife steel but as one of the softer stainless steels may be sharpened easier than other but will not hold an edge like a harder stainless steel. It has moderate corrosion resistance and toughness which might let the 430F chip or break. This makes it a possible steel for cutlery knives but it will not make a good blade for knives with higher performance demands.Conclusion
The balance of corrosion resistance, machinability and mechanical properties as well as aesthetic appeal make the 430F a good choice for the production of fasteners, gears, architectural trims as well as household appliances.Stainless steel 430F datasheet
