{"product_id":"starblaze-ss309l-rod","title":"StarBlaze SS309L Rod","description":"\u003cp\u003eStarBlaze SS309L series consists of premium, rutile-coated stainless steel stick welding electrodes (rods). Classified under AWS A5.4 as E309L-16, this electrode features an elevated chromium and nickel content, making it the industry benchmark for joining highly dissimilar metals and applying stainless steel buffer layers.\u003cbr\u003e\n \u003cbr\u003e\n Core Product Features\u003cbr\u003e\n Dissimilar Metal Mastery: The over-alloyed chemistry (23% Cr \/ 13% Ni) compensates for dilution when welding stainless steel to mild carbon or low-alloy steels, preventing the formation of brittle martensite structures.\u003cbr\u003e\n Intergranular Corrosion Resistance: The extra-low carbon content (? 0.04%) limits chromium carbide precipitation at the grain boundaries, preserving maximum corrosion protection in the heat-affected zone.\u003cbr\u003e\n Hot-Crack Mitigation: Formulated to maintain a high ferrite content (FN 8–15) in the weld deposit, providing robust resistance against hot cracking during cooling.\u003cbr\u003e\n Premium Operator Handling: Delivers a highly stable, low-spatter arc on both AC and DC systems, accompanied by a self-peeling slag that reveals a clean, finely rippled weld profile.\u003c\/p\u003e","brand":"StarBlaze","offers":[{"title":"E309L \/ 2.5","offer_id":56031586910500,"sku":"E309L.S25.SB","price":1040.0,"currency_code":"INR","in_stock":true},{"title":"E309L \/ 3.15","offer_id":56031586943268,"sku":"E309L.S315.SB","price":1040.0,"currency_code":"INR","in_stock":true},{"title":"E309L \/ 4","offer_id":56031586976036,"sku":"E309L.S40.SB","price":1040.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1016\/4938\/3716\/files\/Screenshot_2026-08-19_at_2.54.16_PM-p10769071636772.jpg?v=1787599539","url":"https:\/\/www.weldtools.in\/products\/starblaze-ss309l-rod","provider":"weldtools","version":"1.0","type":"link"}
