Frequently Asked Questions

What is the difference between 304 and 316 stainless flanges?+

316 stainless contains 2-3% molybdenum which provides significantly better resistance to chloride pitting and crevice corrosion. 316 is preferred for marine, chemical, and pharmaceutical applications.

What is the L grade designation?+

The L suffix (304L, 316L) indicates low carbon content (0.03% max vs 0.08%). Low carbon grades resist sensitization during welding, preventing intergranular corrosion in the heat-affected zone.
