Chemical Composition of C45

Chemical Composition of C45

Chemical Composition of C45:

C45 steel is a medium carbon steel offering moderate tensile strengths. C45 steel material is capable of throughout hardening by quenching.

The following substances are frequently found in C45 material, also known as 1.0503 or EN 10083-2 C45 steel :

Carbon (C): 0.42 to 0.50 percent

Silicon (Si) 0.15% to 0.35%

Manganese (Mn): 0.50–0.80 percent

Phosphorus(P) Maximum 0.045%

Sulphur(S): maximum 0.045%

The chemical composition of C45 steel typically falls within these ranges. The material’s strength and hardness are influenced by its carbon content, while its overall toughness and strength are improved by silicon and manganese. To maintain good weldability and avoid negative effects, phosphorus and sulphur are only present in small amounts.

It’s crucial to keep in mind that the precise composition may change based on the production method, heat treatment, and particular standards’ needs. It is advised to check the pertinent standards or the manufacturer or supplier for accurate and current information on the chemical makeup of C45 steel.

Charecteristic of C45 material:

Medium carbon steel with a moderate tensile strength is 45 steel.

The C45 steel material can undergo continuous quenching hardening.

A quick quench for uniformly higher material hardness.

Tempering on a few areas, but can also be HRC 55 induction- or flame-hardened.

The two most prevalent conditions in which the C45 steel grade is provided are untreated and normalised.

It is offered in a number of versions (identified by additional letters) that offer minor changes in chemical composition.

Easy Weldability is decreased, but machinability should be comparable to that of ordinary grade mild steel.
