The ESAB OK 63.30 is a high-quality LMA (Low Moisture Absorption) stick electrode classified as E316L-17 under AWS standards. Designed specifically for welding austenitic stainless steels of the 18% Cr \/ 12% Ni \/ 2.8% Mo type, this electrode is engineered to meet the rigorous demands of industrial fabrication where corrosion resistance is paramount. The ‘L’ designation indicates an extra-low carbon content (maximum 0.04%), which significantly reduces the risk of carbide precipitation and subsequent intergranular corrosion, making it ideal for applications involving corrosive media.<\/p>\n
This 2.5mm electrode features a rutile-acid coating that provides excellent arc stability and operability on both AC and DC+ currents. The slag system is formulated to cover the weld bead completely, protecting it from oxidation during cooling, yet it detaches easily\u2014often self-releasing\u2014to reveal a bright, smooth weld profile with fine ripple formation. The OK 63.30 is also suitable for welding stabilized stainless steels of similar composition, provided the working temperature does not exceed 400\u00b0C (approx 750\u00b0F).<\/p>\n
Technical specifications include a typical yield strength of 460 MPa and a tensile strength of 570 MPa, with elongation around 40%. The chemical composition is tightly controlled to ensure consistent mechanical properties and ferrite content (FN 3-10), providing good resistance to hot cracking. It is widely utilized in the chemical, petrochemical, and food processing industries where 316L materials are standard.<\/p>\n","protected":false},"excerpt":{"rendered":"Extra-low carbon stainless steel electrode for welding steels of the 18Cr 12 Ni 2.8Mo-type.","protected":false},"featured_media":0,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[1964,1959],"product_tag":[],"class_list":["post-1751035","product","type-product","status-publish","product_cat-all-stainless-mig-tig-electrodes","product_cat-welding-wires-and-electrodes","pa_aws-spec-e316l-17","pa_brand-esab","pa_diameter-2-5mm-2","pa_diameter-2-5mm","pa_grade-473","pa_packaging-10lb-tube","pa_packaging-description-1-7kg-tube","pa_polarity-ac-or-dc","pa_polarity-ac-or-dc-2","pa_weld-process-stick","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"yoast_head":"\n
