What is the concept of carbon equivalent? What is the relationship between carbon equivalent and weldability?
There are a lot of carbon equivalent indexes such as tensile strength, yield strength of carbon equivalent, carbon equivalent, welding carbon equivalent, and crack sensitivity index (which is essentially carbon equivalent).
In order to facilitate the expression of strength properties of these materials and welding performance simply to carbon equivalent to said through the statistics of test data.
C equivalent =[C+Mn/6+ (Cr+Mo+V) /5+ (Ni+Cu) /15]*100% formula: C, Mn, Cr, Mo, V, Ni, Cu are elements in the steel contentCarbon steel, determine the strength and weldability of the main factors is the carbon content. Alloy steel (mainly low-alloy steel) in addition to all kinds of alloy elements on the strength of carbon steel and welding also plays an important role.
