WELDING

The grade 446 stainless steel can be easily welded using most of the traditional methods except oxyacetylene welding. Type 308 welding material can be used if required, but it will not exhibit scaling resistance equal to the base metal. Differences in coefficient of thermal expansion of base and weld metal has to be taken into consideration.

 

HEAT TREATMENT

ANNEALING

Annealing should be carried out at a temperature of 1400/1525ºF (760/830ºC) followed by air cooling. Again, as with other high chromium steels, avoid soaking at or slow cooling through the temperature range 700/1000ºF (370/525ºC) to prevent embrittlement.
