S44800

Official original A493−09(Reapproved2013) PDF1/2 Table 1 and Notes A–B; Mass fraction wt%. ; The original symbol Cb corresponds to Nb; retain mapping description and do not create separate elements. ; All sum and coupled requirements must be verified using measured composition from the same heat; individual elements being within their ranges does not guarantee compliance with the sum requirements.. ; Si is blank in the table for S44401; if not specified, do not fill in zero; Ti/Nb each ≤ .80 is an envelope derived from non-negative values and a total ≤ .80, and does not represent independent standard limits. ; This standard covers wire/wire rod for cold heading and cold forging; actual supply, dimensions, delivery condition and properties require separate verification..

Based on original SAE J405 JUN1998, Table 1; Mass fraction wt%, note 1: values without a stated range or minimum are maxima; a dash means unspecified and is not entered as zero. Note 5: Cb and Nb denote the same element; Alloying elements must be checked against the corresponding UNS row and additional conditions. Note 4: ordinary carbon analysis is reported to 0.01%, and low-carbon types to 0.001%; This is reporting precision and does not widen composition limits. Type names in original Table 1 may include a common name or a ASTM designation footnote; Search aliases follow only explicit correspondences on the same row; substitution across standards is not assessed automatically. 1998 is the actual composition basis; The specified newer edition has not been verified; equivalence between editions is not assumed. Combined C+N content ≤0.025%, with the individual maxima also satisfied.

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: (C+N) 0.025; See the limits below for the specific coupled requirements.
