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 ...
The weldability, also known as joinability, [1] of a material refers to its ability to be welded. Many metals and thermoplastics can be welded, but some are easier to weld than others (see Rheological weldability). A material's weldability is used to determine the welding process and to compare the final weld quality to other materials.
The hardenability of ferrous alloys, i.e. steels, is a function of the carbon content and other alloying elements and the grain size of the austenite. [1] The relative importance of the various alloying elements is calculated by finding the equivalent carbon content of the material.
There are a couple of noteworthy enhancements with ASTM A992. Material ductility is well defined since a maximum yield-to-tensile strength ratio of 0.85 is specified. Additionally, weldability is improved since a maximum carbon equivalent value of 0.45 (0.47 for Group 4 and 5 shapes) is required. ASTM A992 is written to cover all hot-rolled ...
904L is an austenitic stainless steel.It is softer than 316L, [1] [2] and its molybdenum addition gives it superior resistance to localized attack (pitting and crevice corrosion) by chlorides and greater resistance reducing acids; in particular, its copper addition gives it useful corrosion resistance to all concentrations of sulfuric acid.
A572 steel is typically used in structural applications due to its high strength, ductility, weldability and corrosion resistance. [4] These applications include structural sections, reinforcing bars, bridges, skyscrapers and houses. [1]

Zone II includes most carbon steels with a carbon content above 0.10%. Steels in this zone can be prone to cold cracks. In this case, it is preferable to use low hydrogen filler and slow the cooling rate during welding process. Zone III includes alloy steels with a carbon content above 0.10% and a high carbon equivalent index. Materials in this ...
