preheat requirements for ah 36 and dh 36 steels

What is the difference between steel grade AH36 and steel

Steel grade A36 is only general strength steel,while steel grade AH36 is high strength steel.Second condition,steel grade AH36 and steel grade A36 is same,the steel grade A36 is just short for steel grade AH36.The shipbuilding steel is produced according to the requirements of classification societies.Table 3-1.Minimum Preheat and Interpass Temperatures for Minimum Preheat and Interpass Temperatures for AISC-Approved Strcutural Steels Prequalified .Preheat for Prequalified Applications. grade 36.over 19 to 38.1 mm (incl.) 66 o C (150 o F) (3/4 to 1-1/2 in.)
