Description
Cobalt Base Alloys ECoCr-A Welding Electrode
ECoCr-A Hardfacing Electrode with a rustile-basic coating. Cobalt Base Deposit of CO-CrW. The Deposit is highly resistant to metal-metal wear and to corrosion up to 800 Degree C. High Resistance to thermal and mechanical Shocks. Good Aptitude to Polishing and to Machining. Soft arc, easy to remove slags, regular and smooth weld profile.
Cobalt Base Alloy Covered electrode produce a medium hardness cobalt-chromium deposit for high temperature applications with good abrasive wear and good impact resistance. It is the most versatile and widely used cobalt alloy with a good balance of abrasion and impact resistance. Chromium carbides contained in the deposit, have excellent resistance to many forms of chemical and mechanical degradation, including galling and cavitations erosion. It bonds well with all weldable steels, including stainless.
ECoCr-A provides resistance to many forms of chemical and mechanical degradation over a wide temperature range. The most generally used cobalt alloy, ECoCr-A attributes include outstanding self-mated anti-galling properties, high temperature hardness, and high resistance to cavitations erosion. Certification to AWS specification – A5.21 ERCoCr-A for bare rod; A5.13 ECoCr-A for coated electrode.
