resistance.<\/p><p>Initially, alloy 904L is developed for the application of corrosion resistance in dilute sulfuric acid, and it is one of the few stainless steels that can maintain full corrosion resistance at temperatures up to 95\u00b0F (35\u00b0C) across the entire concentration range from 0 to 100%. Besides, 904L also has excellent corrosion resistance to many inorganic acids (e.g., phosphoric acid) and most organic acids. However, acid and acid solutions containing halogen ions are very corrosive, and the corrosion resistance of 317L, 317LMN, and 904L may not be able to defend.<\/p><p>Frictional distillate oils usually require the material superior to 316L, and 317Mn is often used. In these hot concentrated alkali solutions, the corrosion resistance of the material is mainly determined by its nickel content. With the nickel content reaching 25%, 904L now has proved to be an excellent alternative to most conventional stainless steels.<\/p><p>For traditional stainless steels such as <a href=\"\/what-is-304l-steel\/\" target=\"_blank\" rel=\"noopener\">304L<\/a> and <a href=\"\/what-is-316l-steel\/\" target=\"_blank\" rel=\"noopener\">316L<\/a>, they are susceptible to chloride stress corrosion cracking under certain conditions. The stress corrosion cracking tolerance of chloride will go up with the increase of nickel and molybdenum content. Therefore, for super austenitic stainless steels such as 904L, it has a higher resistance to chloride stress corrosion cracking.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section

However, for 904L, if it stops to form when the temperature goes beyond 2012\u00b0F (1100\u00b0C), the material shall be quenched directly so that the material can be used without subsequent heat treatment. More importantly, the entire workpiece can be quenched when temperature is higher than 2012\u00b0F (1100\u00b0C). When local heating or cooling is below 2012\u00b0F (1100\u00b0C), and the cooling goes too slow, hot forming shall follow the subsequent operations of annealing and quenching. 904L shall be annealed between 1940 and 2084\u00b0F (1060-1140\u00b0C).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-068826b elementor-widget elementor-widget-heading\" data-id=\"068826b\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Processing<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e4e337a elementor-widget elementor-widget-text-editor\" data-id=\"e4e337a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The hardening rate of 904L in cold forming makes it less machinable than 410 and 304 stainless steels.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-649f2b1 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"649f2b1\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-b143ec6\" data-id=\"b143ec6\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-5832342 elementor-widget elementor-widget-heading\" data-id=\"5832342\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Welding of 904L Steel<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3eac383 elementor-widget elementor-widget-text-editor\" data-id=\"3eac383\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>904L can be welded with most standard workplaces.
