ASTM standards are globally recognized references for material testing and specification. They define the exact chemical composition of materials, classifying them into groups with shared characteristics. By design, ASTM standards precisely identify a material’s composition, mechanical properties, and material family.

Below we present a library built from years of experience, covering the most commonly used ASTM materials in marine and industrial projects. The list does not include the ASTM document, which can be purchased at ASTM,  but provides a concise description and applicable fields for the most widely used materials, intended as a practical reference for your projects.

Fittings
Flanges / Forgings
Castings (valves, valve casing)
