Principal Design Features
|
|
Similar in chemistry and performance to 430 stainless steel, 434 has the addition of molybdenum to increase its resistance to corrosion. The alloy combines a ferritic structure with good fabricability and strength characteristics.
|
|
|
Applications
|
|
Primarily used in automotive trim applications and other exterior environments.
|
|
|
Machinability
|
|
Although not commonly available in machinable forms, 434 has been successfully machined using all standard methods.
|
|
|
Forming
|
|
Excellent ductility allows a wide variety of successful forming operations including shearing, blanking and deep drawing.
|
|
|
Welding
|
|
434 can be successfully welded using most common methods. Standard type 308 filler material may be used, although if the part will undergo thermal cycling, it is recommended to use a filler material of similar composition. Material must be thoroughly cleaned after welding for maximum corrosion resistance.
