EN 10250-2 Grade C35E normalized and tempered (+NT) introduction

Steel C35E is suitable for slightly higher loaded parts of higher dimensions (large forged parts) and complexer forms as well as for higher requirements to uniformity of properties and to surface quality in vehicle and machine engineering. (e.g. transmission parts, crankshafts).
As a bright steel product the steel is used in the form of bars, bright, straight, in various conditions (see DIN EN 10277 : 1999-10).
