Nickel alloys are widely used in instruments, electronic communications, pressure vessels, corrosion-resistant equipment, and are also extensively used in aerospace and high-end special applications. Machinery and equipment manufacturing and other industries rely heavily on nickel alloys as a crucial metal raw material for industrial development. With my country's industrial progress, the demand for high-end nickel alloys has increased. With increasing demand for production and import/export, converting international standards into national standards will help upgrade the non-ferrous metals industry and boost domestic manufacturing. Development is of great significance. GB/T 42513 aims to establish a complete and practical system for determining chromium, phosphorus, niobium, molybdenum, aluminum, vanadium, and other elements in nickel alloys. Standard methods for elements such as silicon, cobalt, copper, and boron are converted into the following international standards.

1 Scope

GB/T 42513.11-2026 is the Chinese national standard covering fourteen elements in a nickel alloy from one XRF measurement - the routine control method for superalloys, where the alloy is most of the periodic table and every element has to be within a narrow band. Part 11 of the series, first edition of this part. It was issued on 28 January 2026 and has been in force since 1 August 2026, as a first edition. The document is under the responsibility of the China Nonferrous Metals Industry Association. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document describes the use of wavelength dispersive X-ray fluorescence spectrometry to determine silicon, manganese, phosphorus, chromium, nickel, copper, molybdenum, cobalt, iron, and aluminum in nickel alloys. Methods for determining the content (mass fraction) of vanadium, titanium, tungsten, and niobium. This document applies to smelted, cold-cast, and forged nickel alloy samples with a carbon content of less than 0.3% and other non-analytical element content of less than 0.2%. Analysis of sample preparation; applicable to the analysis of silicon, manganese, phosphorus, chromium, nickel, copper, molybdenum, cobalt, iron, aluminum, vanadium, titanium, tungsten and niobium content (mass fraction) in the above nickel alloys. The determination of the number of elements is shown in Table 1. Table
