Frequently Asked Questions
What is the difference between 304 and 316 Stainless Steel Flanges?
304 is the most common grade, while 316 contains molybdenum for superior corrosion resistance, especially against chlorides.
Which stainless steel grade is best for marine applications?
316 and 904L grades are highly recommended for marine and chloride-rich environments due to their excellent corrosion resistance.
Are Stainless Steel Flanges suitable for high-temperature applications?
Yes, grades like 310, 321, and 347 are designed to withstand elevated temperatures without losing strength.
