carbon equivalent formula and ce calculator

Why carbon content is important? The most widely used metal material in the industry is carbon steel and its alloys. Carbon steel is compounded based on carbon content and alloying elements. carbon content is one of the elements with the most influence on the nature or characteristics of a metal. The more carbon content, the metal becomes stronger and harder. however, hard material has brittle characteristics or is less resilient and increases the likelihood of cracking in the weld joint area. Explanations of the carbon equivalent One of the biggest problems in the welding technology of high-strength fine-grained steels is cold cracking. In general, the cold cracking tendency of micro-alloyed fine-grained steels is low. However, if higher carbon contents are present, there may be hydrogen-favored cold cracking in the heat affected zone. Since other alloying elements promote cold cracking in addition to carbon, carbon equivalents are often used to estimate crack sensitivity. There are numerous formulas for describing the carbon equivalent, in which the individual alloying elements are weighted differently. The carbon equivalent may thus generally be understood as a measure of the inclination of a cold cracking material depending on its chemical composition. It also serves as a basis[…]
