Why Choose MAGMAWELD E312?
- Unmatched Versatility: Weld dissimilar metals (stainless/mild steel, low alloy steel) and repair high-carbon, armour, or austenitic manganese steel.
- Superior Crack Resistance: 50% delta-ferrite weld metal prevents cracking in stress-sensitive applications like tool/die repair and gear tooth rebuilds.
- Industrial-Grade Performance: Self-releasing slag, easy arc striking, and smooth bead formation ensure efficiency on flat, horizontal, vertical, and overhead positions (PA-PF).
- Global Quality Standards: Manufactured to AWS/ASME and EN ISO specifications for reliable, consistent results.
Applications
Ideal for heavy-duty tasks: dissimilar metal joining, galvanized steel welding, buffer layers on cutting blades, and repairing worn/cracked components in automotive, mining, and manufacturing industries.
Quality Assurance
Backed by Magmaweld¡¯s market-leading reputation, each electrode undergoes rigorous testing to meet mechanical properties (20% elongation, 50J Charpy V-notch at 20¡ãC) and chemical composition standards.
Differentiators
Unlike standard electrodes, E312 excels in extreme conditions¡ªhandling high-carbon steels and providing non-scaling performance up to 1100¡ãC, making it indispensable for critical repairs.
FAQ
Q: Can E312 be used on AC power?
A: Yes, it performs equally well on AC and DC+ polarity.
Q: How to store unused electrodes?
