Stainless Steel 440A Applications | This alloy has been used in aircraft components such as landing gear and structural sections, valves, shafts, and components in the petrochemical and nuclear industries. |
Stainless Steel 440A Machinability | This is a tough machining stainless steel. Although it can be machined in all conditions, best results can be obtained in condition H1150M. Compared to type 304 stainless, speeds should be roughly 25 % lower for optimum tool life and finish. |
Stainless Steel 440A Forming | This alloy can be formed using conventional techniques with the degree of formability being limited only by its high initial yield strength. |
Stainless Steel 440A Welding | Best welded in the solution annealed condition, using 440A filler material. Both resistance and inert gas shielded methods are acceptable. |
Stainless Steel 440A Heat Treatment | CONDITION A--Soak at 1700 F (927 C) and cool below 60 F (16 C) for 1 hour. CONDITION RH 950- Treat Condition A material at -100 F(-73C) for 2 hours, air warm to room temperature (within 24 hours of solution treatment). Then heat cold treated material to 950 F(510 C) for 4 hours and air cool. CONDITION H950, H1000, H1050, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool. |
Stainless Steel 440A Forging | Soak at 2150 F(1177 C) for 1 hour prior to forging. Do not work below 1750 F(954 C). All forgings should be solution treated prior to final hardening. Air cool to room temperature after forging. |
Stainless Steel 440A Hot Working | 13-8 can be satisfactorily hot worked. Hot worked material must be solution annealed prior to hardening for reliable results. |
Stainless Steel 440A Cold Working | Despite its high initial yield strength, this alloy can be satisfactorily cold worked. |
