A194 GRADE 8T

ASTM A194/A194M—2020 chemical requirements for nut materials, mass fraction wt%; Cold heading supply or finished product strength cannot be directly inferred from the grade composition. Table 1 Note C: Values without a specified lower limit or range are upper limits; Ellipses indicate no requirement; measurement or reporting is not required, and shall not be filled as zero. Table 1 Note A: Intentional addition of Bi/Se/Te/Pb is not permitted; This exception applies only to types where Se is explicitly specified in 6F, 8F, and 8FA; Se shall not be added to all types. Note E: Finished product analysis where S exceeds the upper limit of 0.060% is technically unsuitable; Finished product analysis deviations shall be verified separately according to the original text; heat limits shall not be relaxed. A suffixes, as well as heat treatment, dimensional, and manufacturing requirements, shall be retained separately; grades shall not be merged based on identical composition. The adoption relationship of ASME SA-194 has not been confirmed for this batch; Original texts of 2016, 2023 and 2026 have not been verified; the displayed composition is based only on 2020. Ti ≥ 5 × (measured C + N) and ≤ 0.70%, N ≤ 0.10%.

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.
