The Exocor Executive ER309L TIG Rod in 0.030″ diameter is a specialized filler metal designed for high-integrity welding applications. Manufactured to meet stringent AWS A5.9 specifications, this rod features a nominal composition of 24% chromium and 13% nickel. This chemistry provides superior heat and corrosion resistance compared to standard 304\/308 grades. The ‘L’ designation indicates a low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during the welding process, thereby maintaining corrosion resistance in the heat-affected zone (HAZ).<\/p>\n
This specific diameter (0.030″) is tailored for precision GTAW (TIG) processes involving thin-gauge base materials or intricate root passes where control is paramount. It is the preferred choice for cladding stainless steel over carbon or low-alloy steels, serving as an effective buffer layer. Additionally, it excels in joining dissimilar metals, such as welding 300-series stainless steels to mild or low-alloy steels, ensuring a ductile and crack-resistant weld deposit. The alloy is also suitable for certain cryogenic applications, offering good toughness at lower temperatures.<\/p>\n
Exocor’s manufacturing process ensures a clean, consistent surface finish on the wire, promoting smooth feeding and a stable arc. This results in high-quality radiographic welds with excellent bead aesthetics and minimal post-weld cleaning requirements.<\/p>\n","protected":false},"excerpt":{"rendered":"Exocor Executive 309L is preferred over ER309 for cladding over carbon or low alloy steels, as well as for dissimilar joints that undergo heat treatment. \n\nThis is a suitable wire for cryogenic applications, depending on temperature range, process control variables and flux selection.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1964,1959],"product_tag":[],"class_list":{"0":"post-1760933","1":"product","2":"type-product","3":"status-publish","5":"product_cat-all-stainless-mig-tig-electrodes","6":"product_cat-welding-wires-and-electrodes","7":"pa_aws-spec-er309l","8":"pa_brand-exocor","9":"pa_diameter-0-030-0-030","10":"pa_diameter-0-030","11":"pa_grade-425","12":"pa_grade-309-309","13":"pa_packaging-10lb-tube","14":"pa_packaging-description-10lb-tube","15":"pa_polarity-dc","16":"pa_polarity-dcen","17":"pa_weld-process-tig-tig","18":"pa_weld-process-tig","20":"first","21":"onbackorder","22":"taxable","23":"shipping-taxable","24":"purchasable","25":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product\/1760933","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/media?parent=1760933"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_brand?post=1760933"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_cat?post=1760933"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/josefgases.com\/stage\/wp-json\/wp\/v2\/product_tag?post=1760933"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
