434 Stainless Steel

UNS S43400

The molybdenum-bearing version of the general-purpose grade (Type 430), Type 433 has the same useful combinations of properties. Adding molybdenum (a nominal 1%), helps improve the corrosion resistance properties of the grade, especially against corrosive road salts in automotive trim applications. As with all Type 430 variations, this alloy is highly magnetic and can be welded with some grain coarsening, embrittlement at ambient temperature and a reduced resistance to corrosion.

Type 434 is generally used for automotive and appliance trims. It has shown more of a tendency to rope during forming than Type 430.
