SACM645 steel round bar
SACM645 steel round bar
SACM645 steel round bar is a kind of alloy structural steel round bar under JIS G4202 standard. SACM645 has high permeation performance and mechanical properties, excellent heat resistance and corrosion resistance, high fatigue strength and good heat resistance, non-temper embrittlement, Passable workability, low plasticity when cold deformation, welding poor hardenability low, generally in the quenched and tempered and infiltration helium.
SACM645 is widely used for manufacturing high fatigue strength, high abrasion resistance, the exact size after heat treatment, high strength and so on.
SACM645 steel round bar details:
1,SACM645 specification: DIA 80-1200mm(forged round bar), 80-1200mm(square bar) Length 3-16 meters
2, SACM645 heat treatment: Quenching,Annealing,Normalizing and Tempering.
3, SACM645 tolerance: 0-+3mm(DIA), 0-+10mm(Length)
