AISI 1045 Carbon Steel Bar

AISI 1045 Carbon Steel round bar
AISI 1045 CARBON STEEL ROUND BAR

ASTM AISI 1045 Steel is a medium carbon, medium tensile steel supplied as hot rolled, forged or normalized. Otai special steel supply 1045 round bar, plate, steel rods, steel bars, hexagonal bar, flat bar, square, pipe/tube. Regarding the specific dimension, please contact our professional team?for any AISI 1045 Steel Round Bar.

1045 has good strength and impact properties, plus good machinability and reasonable weldability in the hot rolled or normalised condition. it?has a low through hardening capability with sections up to around 60mm only generally recommended as suitable for through hardening and tempering. However 1045 steel can be successfully flame or induction hardened in the as rolled or normalised condition resulting in surface hardnesses of up to Rc 54 – Rc 60 depending upon the quenching medium employed, the type of set up and section size etc. Core strengths will not change.
