Low-carbon Cr-Mo QT steel — between 25CrMo4 and 30CrMo4. Excellent weldability for a QT grade (low C). Good hardenability for medium sections. Primary use: high-pressure gas cylinders (EN ISO 9809-1). Also used for pressure vessels, boiler parts, and automotive components where weldability + moderate strength are needed.
