Principal Design Features
|
|
A basic ferritic non-heat treatable stainless steel. Its strengths are in ductility, formability, good corrosion and oxidation resistance, thermal conductivity and finish quality.
|
|
|
Applications
|
|
Appliance, automotive and architectural trim, vaults, heat exchangers, scientific apparatus and vending machine components.
|
|
|
Machinability
|
|
Rated at 60 % of B1112. Relatively easily machined in all common procedures.
|
|
|
Forming
|
|
Similar in forming characteristics to 304 stainless steel without the same degree of ductility. It does not, however, work harden greatly.
|
|
|
Welding
|
|
All common welding methods used for stainless will be successful with 430. Filler metal should be AWS E/ER308 or 312.
|
|
|
Forging
|
|
Bring the workpiece to 1500 F (816 C), then on quickly to 1900 F (1038 C). Prolonged exposure at this temperature will cause grain growth. Do not work this material at less than 1500 F (816 C). Air cool to room temperature and anneal.
|
|
|
Hot Working
|
|
Generally the recommended method of hot forming is to work the material at between 1300 and 1500 F. Hot forming is only required on heavy sections.
|
|
|
Annealing
|
|
Soak at 1500 F, furnace cool (50 F/hour) to 1100 F, then air cool.
|
|
|
Hardening
|
|
430 does not respond to hardening by heat treatment.
