Revision of A414/A414M-14(2019) Standard Specification for Steel, Sheet, Carbon, and High-Strength, Low-Alloy for Pressure Vessels


This ballot item is in response to multiple inquiries in the industry expressing confusion and misinterpretation, associated with the titanium equation "Ti = the lesser of (3.4N + 1.5S) or 0.025%". This equation is specified in the formability grades and structural grades in various specifications in addition A414. To address this issue, agreement was established at the Fall 2022 subcommittee meeting, to simplify the titanium requirement by specifying Ti = 0.025% maximum and deleting the footnote specifying the titanium equation. This change serves to eliminate ambiguity and will have no effect on the current practices established by steel producers in the industry. Note, this issue was previously balloted for ASTM A1011, and approved with no negatives or comments. To establish harmony, this issue is currently being balloted for ASTM A1008, A1018, and A1083
