It is specifically engineered for high-temperature, high-pressure industrial environments, such as power generation facilities, chemical plants, and refineries.\u003cbr\u003e\n \u003cbr\u003e\n Technical Classifications \u0026amp; Meanings\u003cbr\u003e\n AWS Classification: E81T1-B2C (or E81T1-B2M depending on gas blend).\u003cbr\u003e\n E: Electrode.\u003cbr\u003e\n 8: Minimum tensile strength of 80,000 psi (approx. 550 MPa) after Post-Weld Heat Treatment (PWHT).\u003cbr\u003e\n 1: All-position welding capability (flat, horizontal, vertical-up, overhead).\u003cbr\u003e\n B2: Indicates a chemical composition containing 1.25% Chromium (Cr) and 0.5% Molybdenum (Mo).\u003cbr\u003e\n C: Requires 100% CO? shielding gas (Note: If designated as B2M, it runs on an Argon\/CO? blend).\u003cbr\u003e\n \u003cbr\u003e\n Target Materials\u003cbr\u003e\n This wire is explicitly formulated for joining heat-resistant, low-alloy Cr-Mo steels, such as:\u003cbr\u003e\n ASTM A387 Grade 11 \u0026amp; Grade 12 plates.\u003cbr\u003e\n ASTM A335 Grade P11 \u0026amp; P12 pipes.\u003cbr\u003e\n Main steam lines, boiler tubes, and pressure vessels subjected to elevated working temperatures.\u003cbr\u003e\n \u003cbr\u003e\n Key Performance Benefits\u003cbr\u003e\n Stress-Relief (SR) Crack Resistance: Kobelco applies strict impurity control to the core flux chemistry of DW-81B2. This grants it exceptional resistance to cracking during required post-weld heat treatment cycles.\u003cbr\u003e\n Excellent Slag Detachability: Utilizes a fast-freezing rutile slag system that completely covers the bead and displays self-peeling detachability as the metal cools, drastically cutting cleanup times.\u003cbr\u003e\n Stable Arc \u0026amp; High Quality: Delivers a highly stable, smooth arc with low spatter generation, leading to flat to slightly convex bead profiles that easily pass strict radiographic inspection.\u003c\/p\u003e","brand":"Kobelco","offers":[{"title":"Default Title","offer_id":56031592120612,"sku":"KB.E81TB2C.F120","price":6125.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/4938\/3716\/files\/flux-cored-wire-p10769073864996.jpg?v=1787599667","url":"https:\/\/www.weldtools.in\/products\/kobelco-flux-cored-wire-e81tb2c-x-1-2","provider":"weldtools","version":"1.0","type":"link"}
