Frequently Asked Questions
Q: What is the maximum service temperature for 446 ss sheet?
A: 446 can be used continuously up to 1100°C (2012°F) in oxidizing atmospheres.
Q: How does 446 compare to 309 and 310 stainless steels?
A: 446 offers better oxidation resistance but lower high-temperature strength than 309/310. It's more economical for pure high-temperature applications.
Q: Can 446 be used in reducing atmospheres?
A: 446 performs best in oxidizing atmospheres. Performance may be limited in reducing conditions.
Q: Is 446 magnetic?
A: Yes, 446 is ferritic and therefore magnetic.
Q: Do you provide material certifications?
A: Yes, we provide full MTC with chemical and mechanical test results.
