* Al、B: There is no specified limit, but the analysis result shall be reported.
* For CS, specify Type B to avoid carbon levels below 0.02 %.
* When a deoxidized steel is required for the application, the purchaser has the option to order CS and FS to a minimum of 0.01 % total aluminum.
① The sum of copper, nickel, chromium. and molybdenum shall not exceed 0.50 % on heat analysis. When one or more of these elements are specified, the sum does not apply; in which case, only the individual limits on the remaining elements shall apply.
② For steels having a carbon content of 0.02 % or less. the limit for columbium is 0.045 % maximum.
