ASTM B449 – Standard Specification for Chromates on Aluminum Description: Abstract This specification covers the requirements relating to rinsed and non rinsed chromate conversion coatings on aluminum and aluminum alloys intended to give protection against corrosion and as a base for other coatings. Aluminum and aluminum alloys are chromate coated in order to retard corrosion; …
ASTM B406 – Standard Test Method for Transverse Rupture Strength of Cemented Carbides Description: Significance and Use 3.1 This test method is used as a means of determining the quality of cemented carbide grade powders by measuring their sintered strength. It is performed on test specimens prepared to specified shape, dimensions, and surface finish; test specimens …
ASTM B390 – Standard Practice for Evaluating Apparent Grain Size and Distribution of Cemented Tungsten Carbides (Withdrawn 2010) Description: Significance and Use The apparent size and distribution of tungsten carbide grains in cemented carbides affects the material’wear resistance and fracture. For a given chemical composition, an increase in the average grain size will result in …
ASTM B380 – Standard Test Method for Corrosion Testing of Decorative Electrodeposited Coatings by the Corrodkote Procedure Description: Significance and Use 4.1 Nickel/chromium and copper/nickel/chromium electrodeposited coatings are widely used for decorative and protective applications. The Corrodkote test provides a method of controlling the quality of electroplated articles and is suitable for manufacturing control, as well …
ASTM B368 – Standard Test Method for Copper-Accelerated Acetic Acid-Salt Spray (Fog) Testing (CASS Test) Description: Significance and Use 3.1 The CASS test is widely employed and is useful for specification acceptance, simulated service evaluation, manufacturing control, and research and development. It was developed specifically for use with decorative, electrodeposited nickel/chromium and copper/nickel/chromium coatings. Use of …
ASTM B338 – Standard Specification for Seamless and Welded Titanium and Titanium Alloy Tubes for Condensers and Heat Exchangers Description: Abstract This specification covers 28 grades of seamless and welded titanium alloy tubes for surface condensers, evaporators, and heat exchangers. Seamless tube shall be made from hollow billet by any cold reducing or cold drawing …
ASTM B331 – Standard Test Method for Compressibility of Metal Powders in Uniaxial Compaction Description: Significance and Use 5.1 The compressibility value obtained by this test is a measure of a material characteristic of the powder. 5.2 The test method is useful in research and development projects, as a quality control test in the evaluation and manufacturing …
ASTM B330 – Standard Test Methods for Estimating Average Particle Size of Metal Powders and Related Compounds Using Air Permeability Description: Significance and Use 4.1 These test methods provide procedures for determining the envelope-specific surface area of powders, from which is calculated an “average” particle diameter, assuming the particles are monosize, smooth surface, nonporous, spherical particles. …
ASTM B328 – Standard Test Method for Density, Oil Content, and Interconnected Porosity of Sintered Metal Structural Parts and Oil-Impregnated Bearings (Withdrawn 2009) Description: Significance and Use The volume of an arbitrary P/M shape cannot be accurately measured by standard techniques such as by micrometers or calipers. Since density is mass/volume, a precise method to …
ASTM B312 – Standard Test Method for Green Strength of Specimens Compacted from Metal Powders Description: Significance and Use 5.1 The green strength value determined under the conditions specified by this test method is influenced by the characteristics of the powder, how it compacts under the specified conditions (that is, the particle to particle bonding that …
