Classified as an <strong>ER309L<\/strong> filler metal, it features a low carbon content (maximum 0.03%) which significantly reduces the risk of carbide precipitation, thereby enhancing resistance to intergranular corrosion. This specific formulation is the industry standard for welding Type 309 stainless steels, as well as for joining 300-series stainless steels to carbon or low-alloy steels.<\/p>\n<p>One of the critical technical advantages of the OK Tigrod 309L is its higher alloy content of Chromium (~24%) and Nickel (~13%) compared to standard 308L rods. This enriched chemistry allows the weld metal to tolerate dilution from mild steel substrates without compromising corrosion resistance or mechanical integrity. Consequently, it is the preferred choice for depositing <strong>buffer layers<\/strong> in cladding applications before applying a final layer of 308L. The 2.5mm diameter provides excellent control for root passes and fill passes on medium-thickness materials, ensuring sound metallurgical bonding in complex fabrication scenarios.<\/p>\n<h3>Technical Specifications<\/h3>\n<ul>\n<li><strong>Classification:<\/strong> AWS A5.9 ER309L<\/li>\n<li><strong>Diameter:<\/strong> 2.5mm<\/li>\n<li><strong>Packaging:<\/strong> 5kg Tube<\/li>\n<li><strong>Shielding Gas:<\/strong> 100% Argon (I1)<\/li>\n<li><strong>Typical Tensile Strength:<\/strong> ~600 MPa<\/li>\n<li><strong>Elongation:<\/strong> ~40%<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"Bare corrosion resisting chromium-nickel welding rod for welding of similar steels of 24% Cr, 13% Ni types. \n\nThe alloy is also used for welding of buffer layers on CMn steels and welding of dissimilar joints.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1964,1959],"product_tag":[],"class_list":["post-1750804","product","type-product","status-publish","product_cat-all-stainless-mig-tig-electrodes","product_cat-welding-wires-and-electrodes","pa_aws-spec-er309l","pa_brand-esab","pa_diameter-2-5mm","pa_grade-425","pa_packaging-10lb-tube","pa_packaging-5kg-tube","pa_packaging-description-5kg-tube","pa_polarity-dc-3","pa_polarity-dc","pa_weld-process-tig","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>ESAB OK Tigrod 309L Stainless Steel TIG Rod 2.5mm (5kg Tube) - Josef Gas<\/title>\n<meta name=\"description\" content=\"Buy ESAB OK Tigrod 309L (ER309L) 2.5mm TIG Rods in 5kg tubes.
