Introduction




ASTM A479 is a standard specification issued by the American Society for Testing and Materials (ASTM) that covers hot- and cold-finished bars of stainless steel, including rounds, squares, hexagons, and hot-rolled or extruded shapes such as angles, tees, and channels for use in boiler and pressure vessel construction. It also covers bars that have been strain-hardened or stabilized after annealing.


ASTM A479 applies to both inch-pound units and SI units. However, unless the order specifies the applicable "M" specification designation, the material shall be furnished to the inch-pound units.


ASTM A479 has been approved for use by agencies of the U.S. Department of Defense. It is also used in other industries such as oil and gas, petrochemical, power generation, nuclear, marine, aerospace, etc.


The main benefits of using ASTM A479 are:


  • It provides a uniform standard for quality and performance of stainless steel bars and shapes.



  • It ensures that the material meets the mechanical properties and chemical composition requirements for its intended use.



  • It helps to prevent corrosion, cracking, stress rupture, creep deformation, and other failures in high-temperature and high-pressure environments.



  • It facilitates compatibility and interchangeability among different products and components.



General requirements




The general requirements for orders and delivery of ASTM A479 shall conform to the applicable requirements of the current edition of Specification A484/A484M. These include:


  • Definitions



  • General requirements for delivery



  • Ordering information



  • Process



  • Special tests



  • Heat treatment



  • Dimensions and permissible variations



  • Workmanship, finish, and appearance



  • Number of tests/test methods



  • Specimen preparation



  • Retreatment



  • Inspection



  • Rejection and rehearing



  • Material test report



  • Certification



  • Packaging, marking, and loading



The heat treatment and mechanical properties of ASTM A479 vary depending on the grade and condition of the material. The heat treatment can be either a separate annealing treatment or a process annealing. The mechanical properties include tensile strength, yield strength, elongation, reduction of area, hardness, and impact energy. The mechanical properties shall be determined by the test methods specified in Test Methods and Definitions A370.


Grades and chemical composition




ASTM A479 covers several grades of stainless steel bars and shapes, which are classified into four categories: austenitic, austenitic-ferritic (duplex), ferritic, and martensitic. Each category has different characteristics and applications.


The austenitic grades are the most common and widely used grades of stainless steel. They have high corrosion resistance, good formability, and excellent weldability. They are also non-magnetic in the annealed condition. Some examples of austenitic grades are 304, 304L, 316, 316L, 321, 347, etc.


The austenitic-ferritic (duplex) grades are a combination of austenite and ferrite phases in the microstructure. They have higher strength and better resistance to stress corrosion cracking than the austenitic grades. They are also more resistant to pitting and crevice corrosion in chloride environments. Some examples of duplex grades are S31803, S32205, S32750, etc.


The ferritic grades are composed mainly of ferrite phase in the microstructure. They have lower corrosion resistance than the austenitic grades, but higher resistance to oxidation and sulfidation at high temperatures. They are also magnetic and have good ductility and machinability. Some examples of ferritic grades are 405, 409, 430, 446, etc.


The martensitic grades are composed mainly of martensite phase in the microstructure. They have higher strength and hardness than the austenitic grades, but lower corrosion resistance and toughness. They are also magnetic and can be hardened by heat treatment. Some examples of martensitic grades are 410, 416, 420, 440C, etc.


The chemical composition requirements for each grade of ASTM A479 are specified in Table 1 of the specification. The chemical composition shall be determined by the test methods specified in Test Methods, Practices, and Terminology A751.
