Jul 11,2016 Carbon Equivalent Limitation for Weldability of Steels#0183;In order to discuss Carbon Equivalency,we must first understand that not all metal alloys are created equal.Even the same grade of alloy such as Stainless Steel 8620 will vary from batch to batch.The factors that affect how the materials mix together are vast and each can and will affect the final material chemistry of the alloy.Welding Carbon Steel Metal Supermarkets - Steel Carbon ContentCarbon EquivalencyCooling RateOther Chemical Composition ConcernsOne of the most important items to consider when thinking about welding carbon steel is the carbon content,which typically ranges from nearly 0% by weight to around 2.1%.1.Low carbon steels contain less than approximately 0.30% carbon 2.Medium carbon steels contain approximately 0.30% 0.60% carbon 3.High carbon steels contain approximately 0.61% 2.1% carbon Each type of carbon steel requires different considerations when welding.Low carbon steel is typically the most readily welded stSee more on metalsupermarketsCarbon Steel WeldabilityWhen the high-carbon steel carbon content is greater than 0.60%,hardening,welding crack sensitivity after the tendency is greater and therefore poor weldability,can not be used in the manufacture of welded pipe structures.Need to be more commonly used in the manufacture of hardness or abrasion of parts and components,the welding work is mainly welding repair.Weldability ofStructural Steels Steel hardenabilitycan be correlated with the carbon equivalent (CE),e.g.CE = C + Mn + Cr +Me + V + Ni + Cu 6 5 15 Steels with CE below about 0.45 are readily weldable with appropriate procedures Preheat and weld heat input should beselected togive cooling rates thatproduce acceptable hardness CE greaterthan 0.45 indicates a
