When this passive layer is scratched or machined it re-forms by itself in the presence of oxygen; that is the fundamental property separating stainless steel from ordinary steel.<\/p>\n<p>Stainless steels are divided into groups according to their crystal structure, and each group strikes a different balance between strength, toughness, formability and corrosion resistance. The chromium, nickel, molybdenum, nitrogen and carbon contents determine that balance, and choosing the right group is often more important than choosing the right grade.<\/p>\n<p>Defence Metal supplies stainless steel to the aerospace, defence, energy, chemical and general manufacturing sectors. Material is supplied with certification, to the standards and sizes requested.<\/p>\n<h4>WHICH GROUP SHOULD YOU CHOOSE<\/h4>\n<p>If corrosion resistance and formability are your priority, <a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/austenitic-steels\/\">austenitic steels<\/a> are the answer; if you need a material that can be hardened by heat treatment and resists wear, <a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/martensitic-steels\/\">martensitic steels<\/a> are suitable. For an economical nickel-free solution there are <a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/ferritic-steels\/\">ferritic steels<\/a>; for applications needing high strength together with chloride resistance, <a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/duplex-steels\/\">duplex steels<\/a>; and in more aggressive seawater environments, <a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/super-duplex-steels\/\">super duplex steels<\/a>. If high strength is required through ageing after machining, <a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/precipitation-hardening-steels\/\">precipitation hardening steels<\/a> should be considered.<\/p>\n<h4>STAINLESS STEEL GROUPS<\/h4>\n<ul>\n<li><a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/austenitic-steels\/\">Austenitic Stainless Steels<\/a><\/li>\n<li><a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/martensitic-steels\/\">Martensitic Stainless Steels<\/a><\/li>\n<li><a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/ferritic-steels\/\">Ferritic Stainless Steels<\/a><\/li>\n<li><a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/duplex-steels\/\">Duplex Stainless Steels<\/a><\/li>\n<li><a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/super-duplex-steels\/\">Super Duplex Stainless Steels<\/a><\/li>\n<li><a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/precipitation-hardening-steels\/\">Precipitation Hardening Steels<\/a><\/li>\n<\/ul>\n<p>If you are not sure which group suits your application, or would like to share your size, standard and certification requirements, <a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/contact\/\">contact us<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Search within this group 33 alloys AISI 303UNS S30300 \u00b7 W.Nr. 1.4305 \u00b7 X8CrNiS18-9 \u00b7 BS 303S31 \/ EN 58MAISI 304UNS S30400 \u00b7 W.Nr. 1.4301 \u00b7 X5CrNi18-10AISI 304LUNS S30403 \u00b7 W.Nr. 1.4307 \u00b7 X2CrNi18-9AISI 310UNS S31000 (310) and UNS S31008 (310S) \u00b7 W.Nr. 1.4845 \u00b7 X8CrNi25-21AISI 314UNS S31400 \u00b7 W.Nr. 1.4841 \u00b7 X15CrNiSi25-21AISI 316UNS S31600 &hellip; <\/p>\n<p class=\"link-more\"><a href=\"https:\/\/www.defencemetal.com\/index.php\/en\/stainless-steel\/\" class=\"more-link\"><span class=\"screen-reader-text\"> &#8220;Stainless Steels&#8221;<\/span>devam\u0131n\u0131 oku<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":3526,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_yoast_wpseo_title":"Stainless Steel \u2014 Austenitic, Martensitic, Ferritic, Duplex, PH | Defence Metal","_yoast_wpseo_metadesc":"Stainless steel groups explained and compared: austenitic, martensitic, ferritic, duplex, super duplex and precipitation hardening grades.","inspiro_hide_title":false,"inspiro_hide_featured_image":false,"footnotes":""},"dm_sektor":[],"class_list":["post-3728","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 -
