According to Rolling Process

CLASSIFICATION OF MATERIAL ACCORDING TO PROCESS AFTER ROLLING 

Rolled material at ÇEMTAŞ are divided into 3 halls according to the operation area of the rolling mill.

Hall A:

Rolled material, Analysis and Measurement Guaranteed materials. No futher process is applied to the material. Hall A supplies are in the lowest price group.
Such materials should be preferred in manufacturing where there is no precise and qualified production, and no heat treatment is applied in the process flow. Also, care should be taken to ensure that the material is not to be used under overload, where it will not be used as a safety part.
Surface cracks and ultrasonic internal error checking are not performed on material of A Hall, materials are excluded from guarantee.

Hall B:

Sand blasting and Straightening processes are applied to the materials. Vacuumed and non-vacuumed materials can be processed in Hall B.

C-D Hall:

Only VACUUM and Sandblasting + Straightened materials can be processed in the C-D Hall. ÇEMTAŞ has divided the C-D Hall materials into 2 classes, to provide the most advantageous material in terms of the most suitable to the customer's needs and the materials to be machined to be machined and forged materials.
C Machinable materials are passed through "Surface Fracture Test" according to EN10221 Class A and "Ultrasonic Internal Failure Control" according to SEP 1920 after sanding + straightening.

C Forging materials are passed through "Surface Fracture Test" according to EN10221 Class C and "Ultrasonic Internal Failure Control" according to SEP 1920 after Sanding + Straightening.

Surface crack control of forged quality materials is made more precise than materials used in machining.

Only round materials (Ø15-80 mm) can enter the C-D hall, all of the alloy steels between 15-80 mm are only produced as C-D halls.

All the materials that have not passed through the C forged hall are in the quality documents " "NOT PRODUCED FOR FORGING”.
