Titanium makes a huge difference in this material. It ties up carbon before chromium can react. A welded SS 316Ti Washer keeps full strength. It maintains high corrosion resistance after heavy welding. Standard 316 rings would sensitize under heat. Ganpat Industrial manufactures UNS S31635 washers in Mumbai. They also produce WNR 1.4571 washers in house. Every item originates from mill certified metal coil. Workers blank punch and cold form each piece. They match your precise drawing requirements every time. Final products ship directly from their Mumbai factory.

Frequently Asked Questions

Is 316Ti Stainless Steel Flat Washer magnetic?

No. The austenitic grain structure keeps it non-magnetic in the annealed condition.

Why pick Austenitic Stainless Steel 316Ti Spring Washer over a plain 316 Washer near a weld?

Titanium locks up carbon before it can form chromium carbide, so a welded 316Ti joint keeps its corrosion resistance while plain 316 can sensitize.

What is the minimum order quantity?

Ganpat Industrial ships from small trial packs up to full container loads — share your size and quantity for a factory-price quote.

Can sizes outside the standard chart be supplied?

Yes. Blanking, CNC punching and cold forming are all done in-house against your drawing or sample.
