Introduction

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. ---ISO 7592.2017 Determination of Chromium Content in Nickel Alloys by Ferrous Ammonium Sulfate Potentiometric Titration; ---ISO 9388.1992 Determination of phosphorus content in nickel alloys by molybdenum blue spectrophotometry; ---ISO 7530-7.1992 Flame atomic absorption spectrometry analysis of nickel alloys—Part 7.Determination of aluminum content; ---ISO 7530-8.1992 Flame atomic absorption spectrometry analysis of nickel alloys—Part 8.Determination of silicon content; ---ISO 7530-9.1993 Flame atomic absorption spectrometry analysis of nickel alloys—Part 9.Determination of vanadium content; ---ISO 11435.2011 Determination of molybdenum content in nickel alloys by inductively coupled plasma atomic emission spectrometry; ---ISO 7530.2015 Flame atomic absorption spectrometry analysis of nickel alloys—Part 1.Determination of cobalt, chromium, copper, iron and manganese content; ---ISO 22033.2011 Determination of niobium content in nickel alloys by inductively coupled plasma atomic emission spectrometry; ---ISO 11436.1993 Determination of total boron content in nickel and nickel alloys by curcumin spectrophotometry. GB/T 42513 is proposed to consist of 13 parts. In addition to the conversion of the above 9 standards, new parts 10 to 13 have been added. This document... Part 11, as follows. ---Part 1.Determination of Chromium Content by Ferrous Ammonium Sulfate Potentiometric Titration; ---Part 2.Determination of Phosphorus Content by Molybdenum Blue Spectrophotometry; ---Part 3.Determination of Aluminum Content Nitrous oxide-flame atomic absorption spectrometry and inductively coupled plasma atomic emission spectrometry Spectroscopy; ---Part 4.Determination of Silicon Content by Nitrous Oxide-Flame Atomic Absorption Spectrometry and Molybdenum Blue Spectrophotometry; ---Part 5.Determination of Vanadium Content by Nitrous Oxide-Flame Atomic Absorption Spectrometry and Inductively Coupled Plasma Atomic Emission Spectrometry Spectroscopy; ---Part 6.Determination of Molybdenum Content by Inductively Coupled Plasma Atomic Emission Spectrometry; ---Part 7.Determination of Cobalt, Chromium, Copper, Iron and Manganese Content by Flame Atomic Absorption Spectrometry; ---Part 8.Determination of Niobium Content by Inductively Coupled Plasma Atomic Emission Spectrometry; ---Part 9.Determination of Total Boron Content by Curcumin Spectrophotometry; ---Part 10.Determination of Trace Element Content by Glow Discharge Mass Spectrometry; ---Part 11.Determination of the content of silicon, manganese, phosphorus, chromium, nickel, copper, molybdenum, cobalt, iron, aluminum, vanadium, titanium, tungsten and niobium by X-ray fluorescence spectrometry (Conventional method); ---Part 12.Determination of Tantalum Content by Inductively Coupled Plasma Atomic Emission Spectrometry; ---Part 13.Determination of Oxygen, Nitrogen and Hydrogen Content by Inert Gas Melting-Thermal Conductivity Method or Infrared Absorption Method.
