Incoloy 825 Tube Plugs, Incoloy 825 Tapered Tube Plugs Manufacturer, Incoloy Alloy 825 Threaded Tapered Plug, Incoloy 825 Heat Exchanger Tube Plugs, Incoloy Alloy 825 Tube Plug.
Incoloy 825 Tube Plug is non-magnetic in the hardened form but may perhaps turn in to magnetic slightly because of welding or cold working. DIN 2.4858 Incoloy Tube Plug is excellent in corrosive atmospheres as in chemical and paper industries along with cryogenic services. Perfect for an extensive range of commercial and home uses.
Incoloy 825 is highly resistant to corrosion. It has a high nickel content, sufficient to resist chloride ion stress corrosion cracking, and a very stable austenite structure. The levels of molybdenum and copper enable the alloy to resist reducing agents and acids. Chromium gives resistance to oxidising conditions, such as nitric acid solutions, nitrates and oxidising salts. The alloy is titanium stabilised to resist pitting and intergranular attack after fabrication, particularly welding, which includes heating in the critical sensitisation temperature range (650°C – 760°C).
Alloy 825 offers exceptional resistance to corrosion by sulphuric and phosphoric acids and is often the most cost effective alloy in sulphuric acid service.
