Carbon equivalent calculation formula software

The official version of the carbon equivalent calculation formula software is a simple and practical calculation software. The latest version of the carbon equivalent calculation formula software can calculate the carbon equivalent according to the user's needs. Through the carbon equivalent calculation formula software, users only need to input the percentage of the chemical composition of the steel type to easily calculate the carbon equivalent. At the same time, the formula can be compared according to the international requirements for carbon equivalent.

Carbon equivalent calculation formula software function introduction

The same element has different X values in different carbon equivalent calculation methods. The X values ​​obtained by different researchers are also different.

Empirical formula for carbon equivalent of carbon steel and alloy structural steel

C equivalent = [C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15]*100%

Where: C, Mn, Cr, Mo, V, Ni, Cu are the content of this element in the steel

The carbon equivalent Ceq (percentage) value can be calculated according to the following formula:

Ceq=C+Mn/6+(Cr+V+Mo)/5+(Cu+Ni)/15

(The allowable deviation of carbon equivalent Ceq is +0.03%) Carbon equivalent CE formula of the International Institute of Welding (IIW)

CE= [W(c) +W(Mn)/6+[W(Cr)+W(Mo)+W(V) ]/5

+[W(Ni)+W(Cu)]/15

Ce (carbon equivalent) evaluation of weldability

CE≤0.4%, good weldability;

When CE=0.4~0.6%, the weldability is slightly poor, and proper preheating is required before welding;

When CE ≥ 0.6%, the weldability is poor and it is a difficult-to-weld material, requiring a higher preheating temperature and strict process methods;

Oxygen, hydrogen, nitrogen, sulfur, and phosphorus in steel are harmful elements that also affect welding performance;

Calculation formula of carbon equivalent of cast iron

CE=[C+0.3(Si+P)+0.4S-0.03Mn]%

                    S in general cast iron is very low, and the influence of Mn is small, so it is often simplified as:

CE=[C+0.3(Si+P)]%
