High Strength ASTM F468 UNS N10665 Studs Manufacturer in India at Best Price
When a joint sits inside a hydrochloric or sulfuric acid stream, an ordinary corrosion-resistant bolt simply will not last - Hastelloy B2's nickel-molybdenum chemistry is what earns it a place on the drawing. Buyers across South Africa, the UAE, Kenya and Canada come to us because our ex-stock inventory across M6 to M64 metric sizes means an order confirmed today ships within days, not weeks.Suppliers of UNS N10665 Eye Bolts and Washer for Reducing Acid Service at Best Price
Every Hastelloy B2 fastener leaves our Mumbai facility with full mill test certification and export packing built for long-haul freight. As a direct manufacturer, not a trading desk, we quote from bar stock - better pricing, faster answers, and a technical team that checks your acid duty, weld condition and thread pitch before you commit.

08 · Buyer Question
DIN 2.4617 Bolt Resistance In Boiling HCl & H2SO4
Hastelloy B2 is built for reducing acids, in oxidizing air it should stay below 538°C (1000°F) to avoid a ductility dip.
HCl, All Conc.: Excellent
Sulfuric Acid: Good
Acetic Acid: Good
Phosphoric Acid: Good
Oxidizing Limit: 538°C
As-Welded: Suitable

Nickel B2 Studs As-Welded Corrosion Behaviour
Why site-welded B2 joints hold up without extra heat treatment as a Hastelloy B2 Fasteners Exporter.
1
Low-Carbon Base
0.02% max carbon starves grain-boundary carbide formation.
2
HAZ Protection
Heat-affected zone stays free of knife-line attack risk.
3
ERNiMo-7 Filler
Matched filler wire keeps weld metal chemistry in range.
4
No PWHT Needed
Joints go straight into HCl service after inspection.
11 · Buyer Caution
Hastelloy Alloy B2 Screws Oxidizing Contaminant Limits
B2's near-zero chromium is a strength in pure reducing acid and a limit worth flagging before you order.
Avoid Ferric Chloride Traces
Avoid Cupric Salt Contamination
Avoid Dissolved Oxygen In HCl
Mixed/Oxidizing Duty: Consider C276
