Incoloy 800 and SS 310
What is the difference between INCOLOY 800 and SS 310?
Incoloy 800 is a nickel-iron-chromium alloy, while 310SS (or 310S) is a stainless steel. Incoloy 800 generally has better creep rupture strength at very high temperatures, while 310SS has good resistance to oxidation and sulfidation at high temperatures.
WHAT IS INCOLOY 800?
This nickel-iron-chromium alloy has good strength and excellent resistance to oxidation and carburization in high temperature environments. Incoloy 800 is also corrosion resistant in many aqueous environments and has been used in some steam power plants due to its resistance to stress cracking.
What is the difference between Inconel 600 and 310 stainless steel?
Inconel 600 is more expensive but has excellent corrosion resistance and high temperature strength. Meanwhile, stainless steel 310 has excellent high temperature strength and good corrosion resistance, making it a more cost-effective choice.
What is the difference between 304 stainless steel and 310 stainless steel?
304 stainless steel is typically used in applications up to 800°F (426°C), while 310 stainless steel can withstand higher temperatures. Corrosion resistance: Both grades offer excellent corrosion resistance, but 310 stainless steel has higher levels of chromium and nickel for enhanced protection in more corrosive environments.
Incoloy 800:
Composition:
The main components are nickel, iron and chromium, with other elements such as molybdenum, copper and aluminum added.
Properties:
It has excellent resistance to oxidation, carburization and chloride ion stress corrosion cracking. It also has good creep rupture strength at high temperatures.
Applications:
Heat exchangers, furnace components, petrochemical equipment and other high temperature applications.
310SS (310S):
Composition:
Austenitic stainless steel with high chromium (25%) and nickel (20%) content.
Properties:
It has good high temperature oxidation resistance, anti-sulfurization performance, and is resistant to carburization and thermal cycling.
Applications:
Furnace components, heat exchangers and other high temperature applications, especially where oxidation and sulfidation are involved.
Key Differences:
Alloy Type:
Incoloy 800 is a nickel-iron-chromium alloy, while 310SS is a stainless steel.
High-Temperature Strength:
Incoloy 800 generally has better creep rupture strength at very high temperatures (above 1100°F or 600°C). 310SS is known for its good oxidation resistance at high temperatures.
Corrosion Resistance:
Both alloys have good corrosion resistance, but Incoloy 800 is more resistant to carburization and chloride-ion stress corrosion cracking.
