{"product_id":"starblaze-cast-iron-ci55-rod","title":"StarBlaze Cast Iron CI55 Rod","description":"\u003cp\u003eStarBlaze CI 55 is a premium, graphite-basic coated pure nickel core welding electrode (rod). Classified under AWS A5.15 as ENi-CI, this rod features a nominal 95% to 98% pure nickel weld deposit, making it the absolute industry benchmark for repairing thin-gauge grey iron castings, correcting foundry defects, and handling applications requiring the highest degree of post-weld machinability.\u003cbr\u003e\n \u003cbr\u003e\n Core Product Features\u003cbr\u003e\n “A graphite basic coated pure nickel core wire electrode designed for joining and repairing grey cast iron components. StarBlaze CI 55 deposits a highly ductile, pure nickel weld metal that offers premium softness and exceptional crack resistance.”\u003cbr\u003e\n \u003cbr\u003e\n Maximum Softness \u0026amp; Machinability: Because pure nickel does not absorb carbon from the cast iron to form hard carbides, the weld deposit remains ultra-soft and easily drilled, tapped, or filed.\u003cbr\u003e\n Low-Amperage Arc Stability: Operates exceptionally well at low electrical currents, keeping heat input minimal and preventing the heat-affected zone (HAZ) from becoming brittle.\u003cbr\u003e\n High Ductility: The pure nickel deposit possesses high elasticity, stretching as the joint cools to absorb shrinkage stresses and prevent hairline cracking.\u003cbr\u003e\n Excellent Wetting Action: The specialized graphite flux allows the molten metal to wash smoothly into contaminated or oily cast textures, minimizing porosity.\u003c\/p\u003e","brand":"StarBlaze","offers":[{"title":"CI55 \/ 3.15","offer_id":56031585665316,"sku":"CI55.S315.SB","price":1495.0,"currency_code":"INR","in_stock":true},{"title":"CI55 \/ 4","offer_id":56031585698084,"sku":"CI55.S40.SB","price":1495.0,"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-p10769071014180.jpg?v=1787599539","url":"https:\/\/www.weldtools.in\/products\/starblaze-cast-iron-ci55-rod","provider":"weldtools","version":"1.0","type":"link"}
