Product Description
Hastelloy C276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition.
ASTM B622 C276 (N10276) is a specification for seamless tubes and pipes made of nickel-molybdenum-chromium alloy (C276) that are commonly used in heat exchangers and boilers. The DIN 2.4819 refers to the European standard for this alloy.
This seamless tube/pipe is known for its excellent corrosion resistance in a wide range of environments, including highly corrosive conditions such as acidic solutions and chloride-containing media. It also offers good mechanical properties and high temperature resistance.

The alloy is highly resistant, particularly to the rapid flow of seawater, making it ideal for marine and seawater applications. Additionally, it finds application in power generation, commercial gas turbines, food processing, chemical processing, cryogenic storage/pressure vessels, tanks .
Positive Material Identification (PMI) |
Guohao Steel can perform PMI testing in house for most grades, or we can work with independent labs to complete PMI in order to meet customer specifications. |
Testing |
In some cases, HT/ET/UT testing of the stainless steel pipes may be required. We can assist you with this requirement. |
