摘要

The steel is to be made by one or more of the following processes: open-hearth, basic-oxygen, electric-furnace, vacuum-arc remelt, electro-slag remelt, or such other process as may be specially approved. The steel may be cast in ingots or may be strand (continuous) cast. The ratio of reduction of thickness from a strand (continuous) cast slab to finished plate is to be a minimum of 3 to 1 unless specially approved. Data in support of mechanical properties, weldability and compliance with the Rules in all respects are to be submitted by the steel manufacturer for review and approval when new or special steels or production methods are proposed or when new steel mills begin production.
