It is specifically engineered under classification DIN 8555: E6-UM-55-G for surfacing and rebuilding unalloyed, low-alloy, and cast steel components exposed to heavy abrasion, severe compressive stress, and moderate impact.\u003cbr\u003e\n \u003cbr\u003e\n Core Product Features\u003cbr\u003e\n “StarBlaze HF 550 is a rutile-coated, air-hardening type hardfacing electrode designed for components subject to severe abrasion and compressive stress. It deposits a highly wear-resistant metal with a typical hardness of 54–56 HRc.”\u003cbr\u003e\n High Wear Hardness: Automatically deposits a robust defensive layer with a hardness profile of 54 to 56 HRc to protect machinery from severe gouging and scratching.\u003cbr\u003e\n Air-Hardening Deposit: Achieves its target hardness purely through ambient cooling in still air, completely eliminating the need for post-weld quenching or heat treatments.\u003cbr\u003e\n Rutile Coating Stability: The specialized flux coating ensures exceptional arc stability, uniform puddle wash-in, very low spatter, and an easily removable slag layer.\u003cbr\u003e\n Porosity-Free Matrix: Formulated to produce highly dense, uniform weld beads that are entirely free from cracks or internal gas pockets under proper operating conditions.\u003c\/p\u003e","brand":"StarBlaze","offers":[{"title":"HF550 \/ 4","offer_id":56031586091300,"sku":"EHF550.S40.SB","price":1410.0,"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-p10769071210788.jpg?v=1787599539","url":"https:\/\/www.weldtools.in\/products\/starblaze-hf550-rod","provider":"weldtools","version":"1.0","type":"link"}
