AISI 1045 1.1191 forged round bar carbon steel round bar 1045 steel Manufacturer
1045 steel is used by both the American Iron and Steel Institute (A.I.S.I.) and the Society of Automotive Engineers (S.A.E.):AISI or SAE 1045.In order to replace or supplement the current standard product grade system, they jointly designed a simple numbering system: Unified Numbering System,referred to as UNS. In the UNS,we can find UNS G10450, it is the number for AISI 1045 steel
AISI 1045 steel Manufacturer and Exporter,supplied with round,square,flat,block,and shaft etc.AISI 1045 is defined as medium carbon steel which has 0.43%-0.5% Carbon.It offers good weldability, good machinability, high strength and impact properties,but low in hardenability because of lack of suitable alloying elements,but it can obtain surface hardnesses 54-60HRC after flame or induction hardening. AISI 1045 is generally supplied in the black hot forged or normalized condition,and has a tensile strength of 570 -700 MPa with surface hardness170-210HB.

Forged Round Bar AISI 1045 Application
SAE 1045/AISI 1045 Carbon Steel is a medium carbon steel which is characterized by good weldability, good machinability, high strength and impact properties in either the normalized or hot forged condition. SAE 1045/AISI 1045 steel is widely used for axles, bolts, forged connecting rods, crankshafts, torsion bars, light gears, guide rods etc.
AISI 1045 steel will also be supplied in a normalized condition.The advantage is that the structure and properties of the steel are uniform. Compared with the annealed steel, due to the fast cooling rate, the amount of pearlite in the steel structure increases, and the pearlite layers and the grains of the steel are refined. Therefore, it has higher comprehensive mechanical properties and can be further heat treatment for final product.
