It conforms exactly to the AWS A5.28 ER80S-B8 international standard.\u003cbr\u003e\n \u003cbr\u003e\n Key Specifications \u0026amp; Applications\u003cbr\u003e\n Target Materials: Specifically designed for welding 9% Chromium – 1% Molybdenum low-alloy, heat- and creep-resistant steels. \u003cbr\u003e\n It is the benchmark filler metal used to join ASTM A335 Grade P9 pipes, ASTM A213 Grade T9 boiler tubes, and ASTM A387 Grade 9 structural steel plates.\u003cbr\u003e\n Chemical Profile: The deposited weld chemistry features a precise blend of 8.0–10.5% Chromium (Cr) and 0.85–1.10% Molybdenum (Mo). This high chromium level gives the joint exceptional scaling and oxidation resistance under high thermal operating stresses.\u003cbr\u003e\n Welding Parameters: Handled via Gas Tungsten Arc Welding (GTAW \/ TIG), operating on Direct Current Electrode Negative (DCEN) polarity using a 100% Pure Argon torch shield. An Argon back-purge gas is essential during root passes to safeguard the backside of the joint from atmospheric oxidation.\u003cbr\u003e\n Common Use Cases: Widely deployed for high-integrity root and fill passes in petrochemical refinery cracking units, chemical distillation plants, and high-pressure steam distribution headers operating up to 600°C.\u003c\/p\u003e","brand":"Kobelco","offers":[{"title":"TG-S9CM \/ 2.4","offer_id":56031591792932,"sku":"KB.ER80SB8.T240","price":1410.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/4938\/3716\/files\/er80s-b2-tig-welding-wire-p10769073701156.jpg?v=1787599667","url":"https:\/\/www.weldtools.in\/products\/kobelco-tig-wire-er80s-b8","provider":"weldtools","version":"1.0","type":"link"}
