SUPRAMAX – 16
Classification : AWS : E7016 , BIS : EB5324H2X
Characteristics : A medium heavy coated, hydrogen controlled all positions electrode, produces smooth weld metal, with nominal spatter loss. The slag is easily removable. The weld metal is resistant to cracking. The welds are of X-ray quality for joining MS to cast steel with very good welding properties.
- High carbon steel to mild steel
- Low alloy steel
- Steel relatively high in sulphur content
- Armour plates
- Steel of unknown composition.
Applications include coaches, ships, heavy duty structures, earth moving machinery.
