The objectives of this API-sponsored research are to: (a) quantitatively characterize the internal hydrogen-assisted cracking (IHAC) resistance of modern 2\u00bcCr-1Mo-\u00bcV steel, in both base metal and weld metal product forms and including the effect of stressing temperature, (b) scope the hydrogen environment assisted cracking (HEAC) resistance of 2\u00bcCr-1Mo-\u00bcV base metal, (c) understand the mechanism(s) for the IHAC and HEAC behaviors of Cr-Mo and Cr-Mo-V steels, centered on hydrogen (H) interactions with microstructure-scale trap sites, and (d) assess application of data and understanding of IHAC and HEAC to determine the role of subcritical H-assisted cracking on a minimum pressurization temperature (MPT) estimate relevant to thick-wall hydrotreating reactor vessels.<\/p>\n<p>This work focused on slow-stable subcritical H cracking and did not examine the effect of H on the fracture toughness for unstable cracking. The temperature dependencies of IHAC of 2\u00bcCr-1Mo-0.3V base plate and weld metal were characterized using slow-rising displacement loading and elastic-plastic fracture mechanics analysis of crack growth measured through direct current potential difference (DCPD). This test method provides a conservative measure of susceptibility of alloy steels to HAC.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Subcritical Cracking of Modern 2\u00bcCr-1Mo-\u00bcV Steel Due to Dissolved Internal Hydrogen and H2 Environment, Research Report<\/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\/api\/\"><b>API<\/b><\/a><\/td>\n<td>2017<\/td>\n<td>170<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":489522,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2642],"product_tag":[],"class_list":{"0":"post-489512","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-api","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\/489512","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\/489522"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=489512"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=489512"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=489512"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
