Incoloy800HT UNS N08811 1.4876 nickel alloy steel bar steel plate

Product Description

Incoloy 800, 800H and 800HT are nickel-iron chromium alloys with good strength, high temperature resistance to oxidation and carburization.In addition to the high carbon content of 800H in the alloy and the addition of up to 1.20% aluminum and titanium in the alloy 800HT, all these nickel steel alloys are the same.The heat-resistant nickel-chromium alloy 800 is the first of these alloys, which has been slightly modified to the heat-resistant nickel-chromium alloy 800H.This modification is designed to control carbon (0.05-0.10%) and grain size to optimize stress fracture performance.Incoly 800HT further modified the combined levels of titanium and aluminum (0.85-1.20%) to ensure optimum high temperature performance.Nickel alloy is double certified (800H/HT), combining two forms of performance.Inchroy 800H/HT alloy for high temperature structural applications.The nickel content makes the alloy highly resistant to the embrittlement caused by chloride ion stress corrosion cracking and sigma phase precipitation.Generally excellent corrosion resistance.In solution annealing condition, 800H and 800HT have excellent creep and stress fracture properties.

UNS 08810/800t (UNS N08811) -- the alloy that is the competition of Incoloy 800H -- is high-coloy heat resistant steel, which has excellent strength, corrosion resistance and oxidation resistance at high temperature, and relatively high tissue stability at high temperature.800H is an alloy that controls the growth of grain and the content of C, Ti and Al through high temperature heat treatment, so as to achieve extremely high creep strength

Provide 800H/HT alloy with double certification.Incoloy 800 is mainly used in the application, the temperature as high as 1100 ° F, 800 h and 800 ht of the alloy is usually used in temperature higher than 1100 ° F, resistance to creep and rupture is a must.The chemical equilibrium gives the nickel steel alloy excellent anti-carburizing, anti-oxidation and nitriding properties.Incoloy 800 ht will not become brittle, even in the use of long range in 1200-1600 ° F, many stainless steel become fragile.The characteristic of nickel-chromium alloy is demonstrated by 800HT.When large amounts of cold form, the grain size produces a distinct fluctuating surface called "orange peel."Heat resistant nickel-chromium alloy 800HT can be used in stainless steel welding process.
