1055 Hardened and Tempered Steel Strip
Hardened and tempered steel strip has comprehensive mechanical properties with good strength, hardness and toughness through hardening and tempering process. Tempering is a thermal process that strengthens steel strips through a controlled heating and cooling process.
We focus on high dimensional accuracy and excellent surface quality and we have been producing high-quality steel strips for different industrial and technical purposes gaining experience to get best results in each market.
