Ganpat Industrial manufactures Hastelloy B3 Washers. We use certified Alloy B3 flat stock. Washers are punched and precision finished in-house. They meet ASTM B335 and DIN standards. This nickel-molybdenum alloy resists hydrochloric acid. It also resists sulphuric acid perfectly. It handles strongly reducing chemical media well. It avoids stress corrosion cracking risks. Standard stainless fails in chloride-heavy plants. It seals pharmaceutical reaction vessels securely. Leaking joints cause costly unplanned downtime. Every dispatched batch is fully traceable.
