General Information |
|
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. |
