SS 304 & SS 316 Flanges in Delhi

Stainless flanges are bought for corrosion, hygiene or chloride resistance, and the grade decision follows the medium: 304 for water, food and general service; 316 wherever chlorides are present, which includes coastal air, pools, dosed cooling water and most chemical duty. Specifying 316 where 304 would do wastes real money, because the price gap is significant in the larger sizes.

SS 304 & SS 316 Flanges — common questions

How do I confirm a flange is really 316 and not 304?
The flange should be stamped with the grade and heat number, and we supply the mill test certificate to match. If the material is critical, a PMI (positive material identification) gun reading takes a minute on site and settles it definitively — we can arrange that. Visual inspection cannot distinguish the two grades.
Will an SS 304 flange bolt to a carbon steel flange?
Yes, provided both are the same standard and class — the bolt circle and hole count come from the standard, not the material. Use an insulating gasket set where galvanic corrosion between dissimilar metals is a concern, particularly in damp or coastal installations.
