Frequently Asked Questions

What is hastelloy c-276?

Hastelloy C-276 is a nickel-chromium-molybdenum-tungsten alloy that offers exceptional resistance to a wide range of severe chemical environments. It contains approximately 57% nickel, 16% chromium, 16% molybdenum, and 4% tungsten, providing outstanding resistance to both oxidizing and reducing acids, pitting, and stress corrosion cracking.

What is the maximum temperature for hastelloy c-276?

Hastelloy C-276 can be used at temperatures up to 1093°C (2000°F) while maintaining its mechanical properties and corrosion resistance. However, the optimal operating temperature range is typically between -196°C (-320°F) and 538°C (1000°F) for most applications.

Is hastelloy C276 the same as inconel C276?

No, Hastelloy C-276 and Inconel C-276 are not the same. While both are nickel-based alloys with similar compositions, they are produced by different manufacturers (Haynes International for Hastelloy and Special Metals Corporation for Inconel). They have slightly different chemical compositions and may exhibit different performance characteristics in certain environments.

Is hastelloy a stainless steel?

No, Hastelloy is not a stainless steel. While both are corrosion-resistant alloys, Hastelloy is a nickel-based superalloy, whereas stainless steel is primarily iron-based with chromium and other alloying elements. Hastelloy alloys typically offer superior corrosion resistance and higher temperature capabilities compared to stainless steels.

What is the difference between Hastelloy c 276 and ss316?

Hastelloy C-276 and SS316 are significantly different alloys. SS316 is a stainless steel containing iron, chromium, and nickel, while Hastelloy C-276 is a nickel-based superalloy with higher nickel content (57% vs 10-14%). Hastelloy C-276 offers superior corrosion resistance, especially in reducing acids, and can operate at much higher temperatures than SS316.

Is Hastelloy more expensive than stainless steel?

Yes, Hastelloy C-276 is significantly more expensive than stainless steel due to its high nickel content and complex alloying elements. However, the higher initial cost is often justified by its superior corrosion resistance, longer service life, and reduced maintenance requirements in aggressive environments.
