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 304L and 316L, 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 elementor-element elementor-element-4c0e8ea elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"4c0e8ea\" 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-0c91eed\" data-id=\"0c91eed\" 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-b18825e elementor-widget elementor-widget-heading\" data-id=\"b18825e\" 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\">904L Compostion and Performance<\/h3>\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-ef151e6 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"ef151e6\" 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-a2762c0\" data-id=\"a2762c0\" 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-fa5ddd6 elementor-widget elementor-widget-image\" data-id=\"fa5ddd6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"765\" height=\"547\" src=\"https:\/\/www.kaysuns.com\/wp-content\/uploads\/2021\/07\/904l_Chemical_Compositions.jpg\" class=\"attachment-large size-large wp-image-7897\" alt=\"904l_Chemical_Compositions\" srcset=\"https:\/\/www.kaysuns.com\/wp-content\/uploads\/2021\/07\/904l_Chemical_Compositions.jpg 765w, https:\/\/www.kaysuns.com\/wp-content\/uploads\/2021\/07\/904l_Chemical_Compositions-300x215.jpg 300w\" sizes=\"(max-width: 765px) 100vw, 765px\" \/>\t\t\t\t\t\t\t\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-6933dca elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"6933dca\" 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-8656106\" data-id=\"8656106\" 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-76b6333 elementor-widget elementor-widget-text-editor\" data-id=\"76b6333\" 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<h2><strong>Processing and Forming of 904L<\/strong><\/h2><p>Cold Forming: 904L is easy to be elongated and shaped. Compared with 304 or 304L, additional content of molybdenum and nitrogen means that it requires a more powerful processing equipment.<\/p><p>Hot forming: The temperature for hot forming is recommended to be between 1562 and 2102\u00b0F (850-1150\u00b0C). Normally, next steps of hot forming are annealing and hardening. 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><p>Processing: The hardening rate of 904L in cold forming makes it less machinable than 410 and 304 stainless steels.<\/p><p>Welding: Alloy 904L can be welded with most standard workplaces. The austenite plate material has uniform austenite structure and uniform distribution of alloying elements, which may cause the redistribution of certain elements such as molybdenum, chromium and nickel after welding. And the separation of these elements retained in the welded casting tissue will influence the corrosion resistance in some environments. However, element separation is less evident in 904L, and this material is usually welded with filler metal of the same composition as the base metal, or even without filler metal.<\/p><p>Welding material for 904L is 20 25 CuL electrode and 20 25 CuL wire.<\/p><h2><strong>Application<\/strong><\/h2><ol><li>Air Pollution Control: Used in the scrubbers in coal-fired power plants.<\/li><li>Chemical Processing: Used in the equipment to produce sulfuric acid, phosphoric acid, inorganic and organic acids and phosphate fertilizers.<\/li><li>Metallurgical Processing: Used in the pickling equipment for sulfuric acid.<\/li><li>Oil and Gas production: Used in offshore processing equipment.<\/li><li>Pharmaceutical Industry: Used in processing equipment.<\/li><li>Pulp and Papermaking: Used in processing equipment.<\/li><li>Seawater and Brackish Water: Used in condensers, heat exchangers and piping systems.<\/li><\/ol><h2><strong>What We Do for 904L Stainless Steel<\/strong><\/h2><p>We provide <a href=\"https:\/\/www.kaysuns.com\/stainless-steel-tubings\/\" target=\"_blank\">904L stainless steel tubings<\/a>, <a href=\"https:\/\/www.kaysuns.com\/blog\/904l-stainless-steel-pipe\/\" target=\"_blank\" rel=\"noopener\">904L stainless steel pipes<\/a> and fittings, flanges in good quality and competitive price.
