ASTM A479 UNS N08926 1.4529 Inconel 926 Alloy 926 Nickel Alloy Pipe Tube
Nonferrous Metal Standards and Nonferrous Alloy Standards
ASTM's nonferrous metals and alloys standards are instrumental in specifying, testing, and evaluating nonferrous metals and alloys (excluding copper) and light metals and alloys and refractory metals. These standards have, and continue to play, a preeminent role in all aspects important to the effective industrialization of light metals and their alloys, primarily with respect to aluminum and magnesium. ASTM nonferrous metals and alloys standards provide the proper procedures for carrying out tests and other evaluation procedures to assess and identify compositions, properties, dimensions, classification, nomenclature, analysis, and quality assurance.
Introduction
Alloy 926 is a super-austenitic molybdenum stainless steel that exhibits excellent resistance to a variety of highly corrosive environments. The combination of molybdenum and nitrogen in its composition resists pitting and crevice corrosion, while copper improves sulfuric acid resistance, and nitrogen improves yield and tensile strengths.

High temperature alloy refers to iron, nickel, cobalt as base, can in the 600-1200 ℃ high temperature and must stress under the action of a kind of metal materials long-term work; And it has higher temperature strength, good resistance to oxidation and corrosion resistance, good fatigue performance, the fracture toughness, and other comprehensive performance. High temperature alloy for a single austenitic organization, in all kinds of temperature has good stability and reliability of the organizations use, based on these properties, and high temperature alloy alloying degree is higher, also called "super alloys", it is widely used in aviation, spaceflight, petroleum, chemical industry, ships is a kind of important material. According to the matrix element to points, high temperature alloy and divided into iron base, nickel and cobalt base, high temperature alloy etc. Iron base high temperature alloy using temperature normally only up to 750 ~ 780 ℃, in the higher temperature of the heat used parts, used the nickel and refractory metal based Characteristics:
1;High temperature alloy with high temperature strength.
2;Good resistance to oxidation and corrosion resistance performance.
3;Good fatigue performance, the fracture toughness, plastic.
Organizational characteristics:
High temperature alloy for a single (austenitic) matrix organization, in all kinds of temperature has good stability and reliability of the organization to use.
High temperature alloy quality requirements:
