铬镍铁合金 800 剥离与. 铬镍铁合金 825 Strip Comparison
铬镍铁合金 825 strips contain more nickel and less iron. It shows that it has superior basic corrosion resistance to Incoloy 800 带子. The high chromium content of these alloys ensures their strong oxidation resistance.
铬镍铁合金 825 strip has a better purity level and stricter regulation of hazardous ingredients than the Incoloy 800 条.
The sulfur contents significantly influence the transient performance of the alloy.
铬镍铁合金 800 strips offer superior transient performance than Incoloy 825 strips overall because the sulfur content regulation for 800 is tighter than it is for 825.
The high chromium content of these alloys ensures their strong oxidation resistance.
铬镍铁合金 825 strips have molybdenum contents. Compared to Incoloy 800 带子, it is more resistant to reducing environments (such as sulfuric and phosphoric acids). Molybdenum also helps with corrosion in crevices and resistance to pitting.
铬镍铁合金 825 strips also have excellent resistance to corrosion at room temperature due to the additional copper element.
When compared overall, 铬镍铁合金 825 strips have more excellent corrosion resistance than Incoloy 800 带子.
What are the Incoloy 800 Strips and Incoloy 825 条带应用?
Applications of Incoloy 825 strips in the chemical process industry range from thermowell and sensors to pumps.
These strips are also used in valve parts for hydrogen and ethylene furnaces and parts for fertilizer and ammonia facilities.
