A Detailed Description Of Incoloy 825 Needle Valve
It is nearly identical to alloy 800 but has better aqueous corrosion resistance. From cryogenic to medium-high temperatures (5400C), it has good mechanical properties and can be significantly strengthened by cold working. The important alloying elements in Incoloy are nickel (38%-46%), iron and chromium (19.5%-23.5%) but in Incoloy 825 Needle valves there are additions of molybdenum, copper and titanium which add to the advantages of Incoloy 825.
