Heat resisting grade 446, 1.4749, S44600

446 is a ferritic heat resisting steel useful up to 1100°C.

Chemical composition ( weight %)

• 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.
