ASTM B127-19
Standard Specification for Nickel-Copper Alloy Plate, Sheet, and Strip
ASTM B127 ASME SB 127 specification covers rolled nickel-copper alloy (UNS N04400) plate, sheet, and strip. The Monel 400 UNS N04400 material shall conform to the required chemical composition for nickel, copper, iron, manganese, carbon, silicon, and sulfur.
ASTM B127 is the standard specification for the nickel-copper alloy Monel 400 (UNS N04400) plate, sheet, and strip. The Monel 400 material supplied by HT PIPE can be either hot rolled or cold rolled which are further classified by thickness.
