Description
BRAND :SILVERSHINE-308L-15
(Basic coated electrode for cryogenic applications)
GENERAL CHARACTERISTICS:
AWSA5 4 E3081-15
BS2926 19.91. B.
DIN 8556 E19 9 LB 20+
- Extra-low carbon basic coated electrode for all positions except vertical top to bottom.
- Exhibits smooth running
- Soft & stable arc with ease of striking, with negligible spatter.
- Easy deslagging.
- Good bead appearance, though somewhat convex profile,
- Austenitic weld deposit with controlled ferrite to prevent cracking, & to derive notch toughness at subzero temperatures down to minus 196°C.
- High resistance to intercrystalline corrosion.
- Welds of consistent x-ray quality.
