Principal Design Features
|
|
This is a version of 430F, a ferritic stainless which substitutes selenium for sulfur to enhance machinability. A basic non-heat treatable, 17% chromium stainless with moderate strength and corrosion resistance.
|
|
|
Applications
|
|
Not to be used for containing high pressure gas or liquid due to its porosity. Successfully used in a variety of aircraft parts including fasteners, gears, shafts and pinions.
|
|
|
Machinability
|
|
Excellent chip breakage due to the addition of selenium. Good speeds and feeds are possible with this alloy.
|
|
|
Welding
|
|
Not recommended for welding due to its high sulfur content. If welding is necessary, utilize low heat settings and filler metal of AWS E/ER430 for best results.
|
|
|
Hot Working
|
|
A two step heating process is recommended starting with bringing the material to 1500 F (816 C), then slowly up to 1950-2100 F (1066-1149 C) before working. Do not work below 1500 F (816 C). Cool in air and anneal fully following cooling to room temperature.
|
|
|
Cold Working
|
|
This alloy will only withstand moderate cold forming.
|
|
|
Annealing
|
|
1250-1400 F (677--760 C), air cool.
|
|
|
Hardening
|
|
This alloy does not respond to heat treatment.
