Сoating
NSW – natural black
IOL – ISO 12924 preservation grease
TEC – TECTYL
Standard
Manufacturer’s standard meeting DIN 22255 and completed with customer requirements.
Hardness
High abrasion resistance is obtained through special heat treatment process making it possible to achieve different hardness in straight and curved portions of links.
Straight portion hardness 345–385 НВ
Curved portion hardness 395–414 НВ
Tensile strength not less than 1000 МPа
