In this case, the carbon content decreases. <\/p>\n<p>Ferritic steels have a ferritic structure at any temperature, as <strong>they do not display any transformation of ferrite into austenite during heating<\/strong>, or a martensitic transformation while cooling.  For this reason, phase changes are not possible and <strong>ferritic steels cannot be changed by heat treatment<\/strong>. <\/p>\n<h3>Basic features of ferritic steels<\/h3>\n<p>Their <strong>level of weldability and corrosion resistance is higher<\/strong> than those of martensitic steels, but <strong>lower than those of austenitic <\/strong>steels.  Chromium makes it a <strong>resistant material, but the absence of nickel decreases resistance and weakens the material in some mediums<\/strong>, such as H2S, NH4Cl, NH4NO3, etc. In the case of steels with a higher chromium ratio (25-30%), the resistance level in heated sulphurous environments is higher. <\/p>\n<p>The <strong>size of the grain<\/strong> of ferritic stainless steels <strong>tends to increase in high temperatures<\/strong>.  In long periods at 450-500\u00baC they become more brittle. <\/p>\n<p>Compared to austenitic steels, ferritic grades also display <strong>high resistance to corrosion under SCC stress<\/strong> (induced by means of nickel amounts of up to 1.5%), particularly in chlorides at high temperatures. They are also resistant to pitting. <\/p>\n<p>By comparison to austenitic grades, ferritic steels are <strong>less ductile and resilient<\/strong>. <strong>Malleability is also lower<\/strong>, but high enough to enable easy cold working.  Ferritic steels achieve <strong>greater ductility and resistance in annealing<\/strong>.  <\/p>\n<h3>\u00a0Most frequent uses:<\/h3>\n<ul>\n<li>Oil or natural gas processing plants<\/li>\n<li>Car exhausts<\/li>\n<li>Ornaments and nitric acid tanks<\/li>\n<li>Hot water tanks<\/li>\n<li>Furnace, nozzle, and combustion chamber parts<\/li>\n<\/ul>\n<div class=\"gap\" style=\"height: 20px;\"><\/div>\n<h3 class=\"title\"><span>Sectors and Parts in which ferritic steel is relevant:<\/span><\/h3>\n<p>At Castinox, ferritic steel is a basic material for manufacturing parts in the<strong> chemistry industry<\/strong>, <strong>water processing industry and the paper industry.<\/strong> At Castinox, we manufacture ferritic steel components for:<\/p>\n<div class=\"one_half\">\n<h4><strong>Ferritic steel valves <\/strong><\/h4>\n<ul>\n<li>Rotary valves<\/li>\n<li>Ball valves<\/li>\n<li>Male valves<\/li>\n<li>Butterfly valves<\/li>\n<li>Guillotine valves<\/li>\n<\/ul>\n<\/div>\n<div class=\"one_half last\">\n<h4><strong>Fluid pump<\/strong> pieces<\/h4>\n<ul>\n<li>Pump bodies<\/li>\n<li>Covers<\/li>\n<li>Cases<\/li>\n<li>Rotors<\/li>\n<li>Etc.<\/li>\n<\/ul>\n<\/div>\n<div class=\"clear\"><\/div>\n<div class=\"gap\" style=\"height: 10px;\"><\/div>\n<div class=\"tabla\">\n<table width=\"600\" border=\"1\">\n<tr align=\"center\">\n<th colspan=\"4\">\n<h3>Ferritic stainless steels<\/h3>\n<\/th>\n<\/tr>\n<tr align=\"center\">\n<th colspan=\"4\">\n<h4>STANDARDS<\/h4>\n<\/th>\n<\/tr>\n<tr>\n<td width=\"150\">SS<\/td>\n<td width=\"150\">ASTM<\/td>\n<td width=\"150\">EN<\/td>\n<td width=\"150\">OTHER<\/td>\n<\/tr>\n<tr>\n<td>&nbsp;<\/td>\n<td>CA15<\/td>\n<td>1.4008<\/td>\n<td>AISI 410<\/td>\n<\/tr>\n<tr>\n<td>&nbsp;<\/td>\n<td>CA40<\/td>\n<td>&nbsp;<\/td>\n<td>&nbsp;<\/td>\n<\/tr>\n<tr>\n<td>&nbsp;<\/td>\n<td>&nbsp;<\/td>\n<td>14059<\/td>\n<td>&nbsp;<\/td>\n<\/tr>\n<\/table>\n<\/div>\n<div class=\"gap\" style=\"height: 35px;\"><\/div>\n<p><a class=\" button alternative-1 medium\" href=\"https:\/\/www.castinox.net\/en\/contact\/\" rel=\"slides[buttonlightbox]\"><i class=\"icon-share-alt\"><\/i>Budget on request<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ferritic stainless steel Ferritic steel is known as direct chromium stainless steel, as its chromium content ranges between 10.5% and 30%.
