SUJ3

JIS G 4805:2008; Heat analysis, mass percent; See the original page for table notes and applicability conditions. This record concerns wire rod, under note a, Cu≤0.20%; Non-wire-rod maximum 0.25%. No edition is stated on the website; Displayed under this source edition; contract applicability is not established

Table 1 Heat analysis, unit mass fraction %. ; Note a: Ni/Cu each ≤0.25%, with Cu≤0.20% for wire rod.. ; Note b: except for the purpose of deoxidation, elements not specified shall not be intentionally added without agreement between both parties; Agreement may allow addition of elements outside the table up to 0.25%, which cannot be presumed as a general guaranteed upper limit for all residual elements. ; Note c: When product analysis is required by the purchaser, it shall be tested according to 14.1; permissible deviations shall be per JIS G0321 Table 4; Heat analysis limits cannot be directly used as product analysis tolerances. ; Note d: Mo impurity for SUJ2/3 ≤0.08%. ; Under 4c, spheroidizing annealing is normally performed but may be omitted when specified by the purchaser.; This manufacturing condition clause itself is not proof that all parts are suitable for cold heading.
