ASTM G65 PDF
One of the more common American Society for Testing and Materials (ASTM) tests to evaluate abrasive wear resistance is the ASTM G Standard Test. The ASTM G wear resistance test is one of the more common low-stress abrasion standardized tests . The consumable list consists of. The ASTM G65 test was modified in this work to reflect more accurately the actual mining conditions in an oil sands operation and create the.

This testing also saves customers considerable time and money in field testing, allowing them to focus their efforts on the most promising products.

The ASTM G65 test simulates sliding abrasion conditions under moderate pressure, using dry sand metered between a rubber wheel and a block coupon of the material being evaluated.

ASTM G65 wear tester. This standard does not g5 to address the safety concerns, if any, associated with its use. It is the intent of this test method to produce data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions.
In this practice these conditions are standardized to develop a uniform condition of wear which has been referred to as scratching abrasion 1 and 3. Low-Stress Abrasion Abrasive wear occurs when hard particles xstm compressed with normal pressure against the surface of a metal, causing material astj. It also provides hard data to an otherwise subjective performance indicator that can be used for marketing and sales.
The comparison will provide a general indication of the worth of the unknown materials if abrasion is the predominant factor causing deterioration of the materials. In addition to daily production quality control, these competencies are also used in the design and quoting of new parts to ensure the right materials and properties are specified for each application.
Materials of higher abrasion resistance will have a lower volume loss. Historical Version s astj view previous versions of standard. Materials of higher abrasion resistance will have a lower volume loss. Note 1In order to attain uniformity among laboratories, it is the v65 of this test method to require that volume loss due to abrasion be reported only in the metric system as cubic millimetres.

Test Conditions Tested for revolutions at a load of 30 lb. These metallurgists provide quality control, design, and analysis services, as well as research on new materials, heat treatments, coatings, and manufacturing processes that keep Kondex and our customers up-to-date on industry trends and new technologies.
Click here to increase the life of your mud rotors. Tested for revolutions at a load of 30 lb. All services are provided at no cost to our customers. In order to attain uniformity among laboratories, it is the intent of this test method to require that volume loss due to abrasion be reported only in the metric system as cubic millimetres. Kondex employs three metallurgists with different industry backgrounds and experience levels. The value of the practice lies in predicting the relative ranking of various materials of construction in an abrasive environment.
This machine enables us to compare materials, heat treatments, and coatings for wear resistance, a major concern for our customers.
It is the responsibility of the user of this standard to establish appropriate safety and zstm practices and determine the applicability of regulatory limitations prior to use. Volume loss data wstm from test materials whose lives are unknown in a specific abrasive environment may, however, be compared with test data obtained from a material whose life is known in the same environment.
The low stress qualifier means that the abradant is imposed on the surface with relatively low normal forces. It is also used in ranking materials of a specific generic type or materials which would be very close in the volume loss rates as developed by Procedure A. Surfaces subjected to low stress abrasion show that material has been removed by hard, sharp particles or other 6g5, sharp surfaces plowing material out in the furrows.

Procedure B should be used when the volume-loss values developed by Procedure A exceeds mm 3. It may be used for highly abrasive resistant materials but is particularly useful in the ranking of medium- and low-abrasive-resistant materials.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Hardness testing equipment, microscopes and digital imaging at Kondex.
Its value lies in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment.
Procedure B should be used when the volume—loss values developed by Procedure A exceeds mm 3.
