A series of large scale tensile tests have also been carried out on 5% Ni butt welds, the results of which are reported in Part 2 of this WRC Bulletin. Charpy-V specimens were subjected to various weld simulation cycles and heat treatments and subsequently broken at a range of cryogenic temperatures. Very high peak temperatures result in a sharp drop in impact strength, especially if high heat input welding is simulated. Very low base metal and HAZ ductilities can result from artificial aging, such as a plastic deformation followed by heating in the 200-400\u00b0C temperature range; this suggests that care must be taken when cold deformation is applied or distortions are corrected in structures made of 5% Ni steel. The ductility can be restored by heat treating the specimens for instance for 1 hr in a very narrow temperature range at around 650\u00b0C.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Part 1: Weldability and Fracture Toughness of 5% Ni Steel-Part 1: Weld Simulation Testing<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/wrc\/\"><b>WRC<\/b><\/a><\/td>\n<td>1981<\/td>\n<td>25<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":696600,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2677],"product_tag":[],"class_list":{"0":"post-696590","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-wrc","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/696590","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/696600"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=696590"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=696590"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=696590"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
