Seamless Tube And Pipe Stainless Steel ASTM A268 AISI 446 DIN 1.4749
Ferritic, heat resisting steel, stainless grade ASTM 446-1, UNS S44600, EN number 1.4749, DIN X18CrN28
can be used at temperatures up to 1100°C (2010°F). However, allowance should be made for low creep strength
at the highest temperatures in order to avoid distortion due to the mass of the steel.

AISI 446 stainless steel Characterized by:
- Extremely good resistance to reducing sulphurous gases
- Very good resistance to oxidation in air
- Good resistance to oil-ash corrosion
- Good resistance to molten copper, lead and tin
Applications
446 stainless steel should be chosen mainly for service at temperatures above 700°C (1290°F)
where the excellent resistance of the material to slag corrosion and sulphidizing gases is particularly advantageous.
Typical applications for 446 stainless steel are:
- Recuperators in the metallurgical and glass industries
- Thermocouple protection tubes
- Sootblower tubes
- Injection nozzles
- Muffle tubes in continous wire annealing furnaces
