Product Details

ASTM A268/A268M UNS S44600 TP446-1 and TP446-2 stainless seamless steel tube

 

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

 
This high temperature stainless steel 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) -- We provide 446, X18CrN28 cold drawn stainless steel wire, bright hard, dia 1.0mm, other dimensions by agreement.
  • metallurgical plant (copper processing)
  •  burners
  • annealing boxes
  • kiln linings
  •  thermocouple tubes
  • injection nozzles
