A194 GRADE 8

ASTM A194/A194M—2020 specifies chemical requirements for nut materials, mass fraction (wt%); grade chemistry alone does not establish cold-heading supply or finished-product strength. Table 1 note C: a value without a stated minimum or range is a maximum; an ellipsis means no requirement and need not be determined or reported—it is not zero. Table 1 note A: intentional additions of Bi/Se/Te/Pb are not allowed; the exception applies only to types 6F, 8F and 8FA where Se is expressly specified, and does not add Se to all types. Note E: product analysis for S above the 0.060% maximum is technically inadvisable; product-analysis tolerances must be checked separately against the source and do not relax ladle limits. The A suffix and heat-treatment, dimensional and manufacturing requirements remain separate; grades are not merged based on matching chemistry. This batch did not confirm adoption of ASME SA-194; the 2016, 2023 and 2026 texts were not checked, and the only composition basis is the 2020 edition.

A match in the materials database does not establish suitability for cold heading or guarantee finished-product strength. Confirmation must consider wire condition, deformation, heat treatment and tests on actual parts.
