TP446-1, S44600 stainless steel tube and pipe, seamless

TP446-1, AISI 446, S44600, EN 1.4749, DIN X18CrN28 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

TP446-1 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.

TP446-1 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 TP446-1 stainless are:

• Recuperators in the metallurgical and glass industries
• Thermocouple protection tubes
• Sootblower tubes
• Injection nozzles
• Muffle tubes in continous wire annealing furnaces
