With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
The American Piping Products carbon equivalent calculator allows for the measurement of what the carbon equivalent is for piping materials that are an alloy steel. Understanding the carbon equivalent of an alloy steel pipe is integral to a piping project, especially when welding will be a necessary part of the process.
Carbon Equivalent and Multiplying Factor for Hardenability of Steel The correlation of the carbon equivalent and the multiplying factors are clarified by a heat conduction analysis BY T. KASUYA AND N. YURIOKA ABSTRACT. The carbon equivalent and the multiplying factor are indexes for hardenability of steels. The carbon
The equivalent carbon content concept is used on ferrous materials, typically steel and cast iron, to determine various properties of the alloy when more than just carbon is used as an alloyant, which is typical. The idea is to convert the percentage of alloying elements other than carbon to the equivalent carbon percentage, because the iron best q390c carbon equivalent
Carbon equivalent formulae were originally developed to give a numerical value for a steel composition which would give an indication of a carbon content which would contribute to an equivalent level of hardenability for that steel.
The weldability of steels is influenced primarily by the carbon content. At higher carbon levels, steels may need either pre- or post- weld heat treatment in order to prevent stress build up and weld cracking. Generally speaking, if the Carbon Equivalent (CE) is 0.35 or below, no pre- or post- weld thermal treatment is needed.
Carbon Equivalent. Carbon Equivalent (CE) is an empirical value in weight percent, relating the combined effects of different alloying elements used in the making of carbon steels to an equivalent amount of carbon. This value can be calculated using a mathematical equation.
Calculate a carbon equivalency formula with Chapel Steel's carbon equivalency calculator.
With the carbon equivalent number, properties of the metal such as application suitability can be determined. Why is Carbon Equivalent Important? Knowing the carbon equivalent, or CE value, is particularly important in situations in which two pieces of metal will be welded together, such as welding two pipes together.

As a world class raw steel materials supplier, BBN steel share aboundant steel stocks with clients all over the world. For GB T 1591 Q390C steel plates stock, the common specifiations are as per below:
The imported product is a Carbon Manganese steel while locally produced tube is typically produced with low Carbon micro-alloyed steel. Thus the Q345 has a much higher Carbon Equivalent content close to the maximum recommended maximum value of 0.45.
This is referenced in NACE Report 8X194 and is a common requirement for carbon steel linepipe; ASTM A106M Supplementary Requirement S6 requires CE(IIW) of 0.50 maximum. CE or Carbon Equivalent (sometimes referred to generically as CEQ) and Pcm are calculations that indicate the weldability of a carbon or low alloy steel.

Q-carbon is harder than diamond by 4870% because carbon is metallic in the molten state and gets closely packed, with a bond length smaller than that in diamond. Unlike all other known forms of carbon, Q-carbon is ferromagnetic, with a saturation magnetization of 20 emu/g and an estimated Curie temperature of approximately 500 K.
The 13C NMR is directly about the carbon skeleton not just the proton attached to it. a. The number of signals tell us how many different carbons or set of equivalent carbons b. The splitting of a signal tells us how many hydrogens are attached to each carbon. (N+1 rule) c. The chemical shift tells us the hybridization (sp3, sp2, sp) of each best q390c carbon equivalent
The correct answer to this question is B. Preheating prevents excessive hardness in the HAZ (heat-affected zone) of a steel plate., making it easier to work with. A piece of steel with a CEV (equivalent carbon content) higher than 0.40 is prone to cracking, shrinking, and distortion if it is not preheated.
