- Content
- This revision of SAE J775 was intended to align SAE standard with ISO standard in order to facilitate global applicability of the standard high temperature alloys and valve materials. Nearly 90% of the information from the current SAE standard and UNS designations have been reproduced with comparison tables incorporating equivalent and or near equivalent DIN and ISO 683-15 designations. Text revisions have been based on current worldwide design application trends and comparison of properties in the tables. Unlike the ISO document, this document applies to materials and properties applied in the design and applications of internal combustion engine valves and does not cover the raw material properties or procurement conditions.
