A series of large scale tensile tests have also been carried out on 9% Ni butt welds, the results of which are presented in the second part. Charpy-V bars were subjected to various weld simulation cycles and subsequent heat treatments and after notching broken at a range of cryogenic temperatures. The simulated welding heat in general, even where varied between wide limits, causes a decrease in impact properties of the steel, although they are still acceptable even at the very lowest test temperatures (-196\u00b0C). Severe embrittlement 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 used or distortions are corrected in structures made of 9% Ni-steel.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Part 1: Weldability and Fracture Toughness of Quenched and Tempered 9% Nickel Steel: 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>1982<\/td>\n<td>24<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":696624,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2677],"product_tag":[],"class_list":{"0":"post-696614","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\/696614","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\/696624"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=696614"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=696614"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=696614"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
