Transmission steels are high-strength steels with elevated Manganese (Mn) values due to low Carbon (C) content.
Transmission steels are classified into grades such as St37-2, St44-2, St52-3, etc. Materials like St44-2 and St52-3 exhibit higher durability.
They are used as cold-drawn with precise dimensional tolerances. Our standard lengths are 3 meters, and surface smoothness is produced within h9, h11 tolerances.
(Upon customer request, protective, specially packaged (burlap, crate, etc.) packaging can be provided.)
