Q&T,N,TMCP steel

Q&T steel are common in the manufacturing industry. Q&T steel should have excellent comprehensive mechanical properties, that is, Q&T steel with high strength and high toughness ensures ensure long-term smooth work parts.
Normalizing, grain refinement and carbide distribution uniformity to improve hardness, improve processing performance, remove the material of internal stress, stable workpiece size, to prevent deformation and cracking.
TMCP means Therm Mechanical Control Process

We can supply Q&T,N,TMCP steel grades are as follows:
