Product Details

ASTM 1045 Medium Tensile Carbon Steel Round Bar / Rod 12-320mm

 

 

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 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.

 

 

 

Applications of AISI 1045 Steel

 

AISI 1045 is widely used for all industrial applications requiring more wear resistance and strength. Typical applications of AISI 1045 are as follows:
  • Gears; Pins; Rams
  • Shafts; Rolls; Sockets
  • Axles; Spindles; Worms
  • Bolts; Ratchets; Light gears
  • Studs; Crankshafts; Guide rods
  • Connecting rods; Torsion bars; Hydraulic clamps

Fabrication and Heat Treatment

 

Machining

AISI 1045 steel has good machinability in normalized as well as the hot rolled condition. Based on the recommendations given by the machine manufacturers, operations like tapping, milling, broaching, drilling, turning and sawing etc. can be carried out on AISI 1045 steel using suitable feeds, tool type and speeds.

 

Welding
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).

Heat Treatment


AISI 1045 is subjected to the following processes:


Forging

  • Heat to 850°C - 1250°C (1562°F - 2282°F)
  • Hold until the temperature is uniform
  • Cool in furnace
     

Annealing

  • Heat to 800°C - 850°C (1472°F - 1562°F)
  • Hold until the temperature is uniform
  • Cool in furnace.
     

Normalizing

  • Heat to 870°C - 920°C (1598°F-1688°F)
  • Hold until the temperature is uniform
  • Soak for 10 - 15 minutes
  • Cool in still air

Stress Relieving

  • Heat to 550°C - 660°C (1022°F - 1220°F)
  • Hold until the temperature is uniform
  • Soak for 1 hour per 25mm of section
  • Cool in still air

Hardening

  • Heat to 820°C - 850°C (1508°F - 1562°F)
  • Hold until the temperature is uniform
  • Soak for 10 - 15 minutes per 25mm of section
  • Quench in water or brine
