| A – Properties for material in the annealed condition. B – Material is identical to the corresponding numeric grade except for the higher guaranteed minimum UTS. C – The H grades were added based on a study of over 5,200 commercial test reports. D – Properties for cold-worked and stress-relieved material. E – Elongation for welded tubing from continuously cold rolled and annealed strip for Grade 9, 12, and 18 will be 12%. | |||||
