Tensile strain mark

SPCE

It is guaranteed that no tensile strain mark occurs on steel plates and strips at their application within 6 months after they are produced and in case of room temperature storage.

SPCEN

It is guaranteed that no tensile strain mark occurs on steel plates and strips at their application within 3 months after they are produced and in case of room temperature storage.

SPCE, SPCEN cold-rolled carbon steel are suitable to manufacturing structural members with simple processing and may be used as some structural parts for automobiles, such as car body frames, middle base plates and various reinforcement plates.
