SIQUAL structural steels are used in the engineering and automotive industries due to high yield strength, tensile strength, elongation, ductility and toughness. Depending on the alloying elements can be further divided into low-alloyed and alloyed steels.
Based on application, we offer:
steels for case-hardening
steels for quenching and tempering
nitriding
