S41045

Based on Table 1 of the original SAE J405 JUN1998; mass fraction wt%. Note 1: a value without a stated range or lower bound is a maximum; dashes mean unspecified and are not replaced with zero. Note 5: Cb and Nb refer to the same element. Verify alloy elements against the applicable UNS row and additional conditions. Note 4: carbon analysis is generally reported to 0.01%, or to 0.001% for low-carbon types. This is reporting precision and does not relax composition limits. Type names in original Table 1 may include common names or a ASTM naming footnote. Search aliases use only explicit same-row relationships; interchangeability across standards is not inferred. 1998 is the actual composition source. The requested newer edition has not been verified, and agreement between editions is not assumed. Nb≥0+9×(C+N), and ≤0.6; check jointly using measured composition from the same heat, not independent combinations of elemental maxima.

Table 1 gives heat-analysis mass percentages; A single value without a stated range or minimum is a maximum; unspecified elements are not entered as zero. ; Cb and Nb are the same element; Where both a formula and a fixed limit apply, the stricter limit is used. ; This is a plate, sheet and strip standard; cold-heading wire applications and actual supply require separate verification. ; Clause 4.1 also requires compliance with the applicable provisions of ASTM A480/A480M; This record displays the heat composition in Table 1; it does not establish verification of A480 or all product acceptance requirements. ; Other elements in the original table: Cb 9×(C+N) min, 0.60 max; See the limits below for the specific coupled requirements.
