ASTM G98 is the Standard Test Method for Galling Resistance of Materials, a technical document used to evaluate how materials behave when exposed to galling under contact and motion. This matters for selecting and comparing materials where surface interaction can affect performance, wear, and reliability. As an ASTM standard, it supports more consistent testing and clearer communication between buyers, suppliers, and engineers.

Overview of ASTM G98

The ASTM G98 standard provides a structured test method focused on galling resistance, helping users assess whether a material pair is likely to seize, transfer, or damage surfaces during contact. It is most relevant when material choice and surface behavior influence functional performance. ASTM G98 is commonly used as a reference for technical evaluation, comparative testing, and quality-related decisions where resistance to galling is an important requirement.

Common use cases of ASTM G98

ASTM G98 is commonly used when engineers need to compare candidate materials for applications involving sliding or threaded contact, where galling can be a concern. It may support material qualification, supplier evaluation, and product development work for metal components and other assemblies sensitive to surface damage. The standard is also useful in laboratory testing and procurement workflows where a defined method helps document and compare galling resistance.

Benefits of using ASTM G98

Using ASTM G98 helps create a consistent basis for evaluating galling resistance, which can improve repeatability in testing and reduce ambiguity in material selection. It supports compliance-oriented purchasing, technical comparison, and quality control by providing a recognized ASTM method. For organizations assessing materials for durability and contact performance, ASTM G98 can help reduce risk, improve documentation, and make product evaluation more reliable.
