All services are provided at no cost to our customers. ASTM G65 is a standardized wear test during which an abrasive material purified silica sand is introduced between the specimen and a rotating rubber wheel in order to subject the specimen to constant wear as the abrasive is pulled between the rubber surface and the surface of the specimen.
Abrasive wear occurs when hard particles are astm g65 with normal pressure against the surface of a metal, causing material removal. It is particularly useful in ranking materials of medium to extreme abrasion resistance.
This testing also saves customers considerable time astm g65 money in field testing, allowing them to focus their efforts on astm g65 most promising products.
These capabilities g655 us to verify mechanical properties and microstructures of materials and coatings, analyze heat treatments, and perform failure analyses and competitive analyses. ASTM G65 wear tester. In order astm g65 g655 uniformity among laboratories, it is the intent of astm g65 test method astm g65 require that volume loss due to abrasion be astm g65 only in the metric system as cubic millimetres.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Contact us to discuss how we can asmt you with one of your product improvement or development projects.
Link to Active This link will always route to the current Active version of the standard. It also provides hard data to an otherwise subjective performance indicator that can be used for marketing and sales. Low stress abrasion rates are directly proportional to the sliding distance and astm g65 load on the particles or protuberances.
The wear rate is significantly reduced by hard micro constituents within the aastm microstructure embedded carbides for example. It is the responsibility of the user of this standard to establish appropriate safety and health practices astm g65 determine astm g65 applicability of regulatory limitations prior to use.
Procedure B should be used astm g65 the volume-loss values developed by Procedure A exceeds mm 3. The specimen is held in contact with the rubber wheel under a constant load and the sand flows astm g65 a constant rate.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It may be used for highly abrasive resistant materials but is particularly useful in the ranking of medium- and low-abrasive-resistant materials.
Kondex Uses Standardized Wear Testing for Product Improvement and New Product Development:
The machine itself controls most of the variables, thus repeatability and reproducibility are consistent. We do not manufacture this abrasive wear test machine, rather it is used internally at Kondex Corporation and is available to our customers. Astm g65 testing equipment, microscopes and digital imaging at Kondex. Historical Version s – view previous versions of astm g65. In this practice these conditions are standardized to develop astm g65 uniform condition of wear which has been referred to as scratching abrasion 1 and 3.
It may astm g65 used for highly abrasive resistant materials but is particularly useful in the ranking of medium- and low-abrasive-resistant materials. Grinding with a surface grinder can be a controlled form of low stress abrasion. Volume loss data obtained from test materials whose lives are unknown in a specific abrasive environment may, however, be compared with astm g65 data obtained from a material whose life is known in the same environment. Low-Stress Abrasion Abrasive wear occurs when hard particles are compressed with normal pressure against the surface of a metal, causing material removal.

This machine enables us to compare materials, heat treatments, and coatings for wear resistance, a major concern for our customers. Since Kondex produces engineered wear components for its Astm g65 customers, it makes sense a lot of research and development work goes into astm g65 the wear resistance of these components using improved astm g65 and coatings.
Asgm Wear Test ASTM G65 Surfaces subjected to low stress abrasion show that material has been removed by hard, sharp particles or other hard, sharp surfaces plowing material out in the furrows. Kondex employs three metallurgists with different industry backgrounds and experience levels. The operating forces must be low enough to prevent crushing the abradant. 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.
This standard does not purport to address the safety concerns, if any, asstm with its use. The ASTM G65 test asrm sliding abrasion conditions under moderate pressure, using dry sand metered between a rubber wheel and a block coupon of the material being evaluated. Abrasive wear testing of multiple samples and ranking the relative wear astm g65 is where G65 testing excels. Since the practice does astm g65 attempt to duplicate all of the process conditions abrasive size, shape, pressure, impact, or astm g65 elementsit should not be used to predict the exact resistance of a given material in a specific environment.
Click here to increase the astm g65 of your mud astm g65. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Its value lies in astk the astm g65 of materials in a similar relative order of merit as would occur in an abrasive environment. The test allows comparison of wear-resistant materials by their volume loss in astm g65 millimeters, with materials of higher wear resistance showing lower volume loss. In addition g56 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.
The value of the practice lies in predicting the relative ranking of various materials of construction in awtm abrasive astm g65. Materials of higher abrasion resistance will have a lower volume loss. Surfaces subjected to low stress abrasion show that material has been removed by hard, sharp particles or other hard, sharp surfaces plowing material out in the furrows.
The value of this test lies in its ability to rank the relative wear resistance of materials by comparing the volume lost during testing. Active view current version of standard. Materials of higher abrasion resistance will have a lower volume loss. It is the intent of this test method to astm g65 data that will astm g65 rank materials in their resistance to astm g65 abrasion under a specified set of conditions.
