Product description
CO-REL® KR·308 （A102E） is a titania-calcium coated stainless steel electrode (AWS E308-16 equivalent) with excellent mechanical properties and hot cracking resistance. Applications include:
Petrochemical reactors
Food processing pipelines
Medical equipment
Optimized for thin-sheet flat welding and low-automation manual SMAW. AC/DC compatible with exceptional AC arc stability, delivering a soft arc, low-spatter, and aesthetic bead appearance. Resists reddening during welding with all-position capability (1G/2G/3G/4G) and robust coating integrity.
Primary Use: Welding 0Cr18Ni9-type stainless structures requiring high crack resistance but moderate corrosion resistance (<300°C service).
Available Diameter (mm): 2.5 / 3.2 / 4.0
Mechanical Performance of Deposit Metal
Tensile Strength MPa (N/mm²): ≥550
Elongation A (%): ≥25
Fillet of T Joint Weld Test: Passed
Baking Temperature Before Welding: 300-350℃ for 1 Hour
Chemical Composition (%)
Welding Parameters
Current Polarity: DC+ / AC
Precautions:
Electrodes shall be baked at 300–350°C for 1 hour before use (immediate consumption post-baking).
Minimize current input & maintain short arc; oscillation width ≤2.5×electrode diameter.
Base metal must be cleaned of oil, moisture, and contaminants pre-weld.
