446 stainless grade combines the following characteristics:
- Good oxidation resistance
- Excellent resistance to sulphidation particularly in reducing conditions. Much better than austenitic heat resisting grades due to absence of nickel
- Good resistance to molten copper, lead and tin
- Poor high temperature strength
- Weldable with austenitic electrodes
Applications include:
Glass making (float glass), metallurgical plant (copper processing), burners, annealing boxes, kiln linings,
thermocouple tubes, injection nozzles
