Product Description

SAE 1045 / S45C /C45 /EN8 Hot rolled carbon steel round bar

Introduction
AISI 1045 steel is a medium tensile steel supplied in the black hot rolled or normalized condition. It has a tensile strength of 570 - 700 MPa and Brinell hardness ranging between 170 and 210.

AISI 1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot rolled / forged condition.

AISI 1045 steel has a low through-hardening capability with only sections of size around 60 mm being recommended as suitable for tempering and through-hardening. However, it can be efficiently flame or induction hardened in the normalized or hot rolled condition to obtain surface hardnesses in the range of Rc 54 - Rc 60 based on factors such as section size, type of set up, quenching medium used etc.

AISI 1045 steel lacks suitable alloying elements and hence does not respond to the nitriding process.

4.SAE 1045 S45C C45 welding ability
Certain facts about welding of AISI 1045 steel are:

AISI 1045 steel is readily welded when correct procedure is followed.
Welding AISI 1045 steel in through-hardened, tempered and flame or induction hardened condition is not recommended.
Low hydrogen electrodes are preferred for welding AISI 1045 steel.
The workpiece is
Pre-heated at 200°C-300°C (392°F - 572°F)
Maintained at the same temperature during welding
Cooled slowly using sand, ashes etc and
Stress relieved at 550°C - 660°C (1022°F - 1220°F).
