Product Introduction
Monel 400, a nickel-copper alloy, is known for its excellent corrosion resistance and strength in harsh environments. It has several equivalent names or classifications based on different material standards. Below are some of the equivalent names or designations used for Monel 400 across various international standards:
UNS N04400: The Unified Numbering System (UNS) assigns this designation to Monel 400, which is widely used in material identification.
ASTM B164, B127, B564: These are the specific ASTM standards that define Monel 400 material, typically for pipe, bar, and flange applications.
Nickel 400: This designation is sometimes used, especially in older industry references or materials data sheets.
Inco 400: Refers to Monel 400 when produced by the International Nickel Company, which was historically one of the largest producers of this alloy.
Summary:
The primary equivalent name for Monel 400 is UNS N04400.
It can also be referred to by Alloy 400, Nickel 400, or Monel Alloy 400 in various contexts.
In some instances, CuNi 70/30 is used as an alternative copper-nickel alloy with properties similar to Monel 400.
