The main constituents of 304 stainless steel - other than iron - are Chromium and Nickel. 304 contains 18 - 20% Chromium (Cr). Chromium is the essential chemical in all stainless steel and it is that which forms the thin passive layer that makes the metal "stainless" 304 also contains 8-10.5% Nickel (Ni).

The influence of chemical elements on the properties of steel are not only dependent on the type of element added to the steel but also the amount of the alloying element that is added. For example, Si can cause low galvanizing thickness at both low concentration or high concentration but in a mid-region will cause the zinc layer to be thick. Element distribution in lean duplex stainless steel welds Nov 19, 2013 · Segregation of alloying elements and nitrogen loss may have a negative effect on the corrosion resistance of autogenously welded duplex stainless steel. The lean duplex LDX 2101® (EN 1.4162, UNS S32101) has less metal element segregation and improved austenite formation compared to other duplex grades and addition of filler metal is not always necessary to achieve good corrosion Global Steel Wire iron and steel companyGlobal Steel Wire S.A. is the celsa Group company engaged in manufacturing wire rod in extensive range of steels and dimensions.

Example - Temperature:EN ISO13916-Tp 90/120-CT. Preheating temperature Tp,with the range of values from 90 Residual Elements in Steel ::Total Materia ArticleResidual Elements in Steel. Residual elements (Cu, Ni, As, Pb, Sn, Sb, Mo, Cr, etc.) are defined as elements which are not added on purpose to steel and which cannot be removed by simple metallurgical processes. The presence of residual elements in steel can have strong effects on mechanical properties.

Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion environments, and it eliminates the need for annealing.
