MMA coated electrode high alloy steel STARINOX 316L SAF-FRO

STARINOX 316L

Stick electrodes range for stainless and heat resistant steels

STARINOX 316L is a semi-basic MMA electrode suitable for the welding of austenitic steels Cr-Ni steels or cast steels containing 16-20%Cr, 10-14%Ni and 2-3%Mo, i.e. AISI 316 and 316L, having an extra low carbon content.

Product Advantages

✔ Excellent resistance to marine corrosion
✔ Easy arc striking and restriking
✔ Excellent operability

STARINOX 316L can be used for welding of stainless steels of the same type whether stabilised or not for services temperatures up to +400°C.
It is particularly suitable for offshore, chemical industry, hydro power plants and general construction applications.

This electrode offers excellent operability and is particularly suitable for downhand butt and fillet welding applications, the 2.5 mm and 3.2 mm diameter electrodes can be used for positional welding.

Exhibits a stable spray arc transfer resulting in excellent weld bead shape and appearance with a slight concave profile in horizontal vertical fillet welds.
There is very little spatter and in combination with the self-releasing slag, post welding cleaning time is maintained to a minimum.
Suitable for use with either AC [minimum OCV 50V] or DC positive. Efficiency 100%.

It meets the classifications:

  • EN ISO 3581-A: E 19 12 3 L R 12
  • AWS A5.4: E 316L-16
