Nov 17, 2011 · ASTM A27 is a cast steel. The chemistry is not controlled to ensure good weldability. It is not prequalified per AWS. I would recommend you obtain a sample for chemical analysis to determine the chemistry and calculate the minimum preheat using AWS D1.1 Annex I as a guideline. ASTM A-27 GR 70 - Boiler and Pressure Vessel engineering Nov 12, 2009 · ASTM A 27 is a specification for steel castings used for general applications. This material is not intended for pressure retaining capability in pressure vessel design (ASME Boiler and Pressure Vessel Code). There are two Grades 70-36, 70-40. The 70 refers to min UTS
