Stainless steel 446 stud bolts have about 23% chromium content, along with minimal nickel and carbon content, making them highly resistant to oxidation and corrosion at temperatures of up to 1000°C (1832°F). The ferritic microstructure provides excellent thermal stability, good mechanical strength, and thermal fatigue as well as stress corrosion cracking resistance. These stud bolts exhibit their strength and dimensional stability even when exposed to heat for extended periods and can be used in exhaust systems, boilers, and heat exchangers.
