pipe, seamless
ASTM A268 ASME SA268 Specification AISI 446-1, UNS S44600, TP446-1,
EN number 1.4749,
DIN X18CrN28 stainless steel tubes.

TP446-1 | 0.20 | 1.00 | 1.50 | 0.040 | 0.030 | 23.0~27.0 | 0.75 | 0.25 |
Seamless steel tubes manufactured by cold finished ( cold rolled
and cold drawn ), then annealed,
pickled, further polishing processing.
Grade 446 is a ferritic, heat resisting, stainless chromium 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
- 446 stainless steel 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.
Material 446 stainless 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 are:
- Recuperators in the metallurgical and glass industries
- Thermocouple protection tubes
- Sootblower tubes
- Injection nozzles
- Muffle tubes in continous wire annealing furnaces
