Monolith M-309L-16 Stainless Steel Electrode


Meets specification AWS А5.4 / SFA-5.4: Е309 / Е309L-16 - CWB approved

Monolith M-309L-16 electrodes are designed for dissimilar welding of austenitic and carbon steels, austenitic stainless steels of such grades as AISI 304, AISI 304L, etc., in the operating temperature range not exceeding 300°C (572°F), as well as for welding of heat-resistant stainless steels such as AISI 309, AISI 309S, etc. They are used for depositing intermediate layers on heat-resistant CrMo pearlitic steels and for cladding of ferritic pearlitic, low and medium alloyed substrates as well as for applying buffer layers prior to overlaying. These electrodes are suitable for welding of tanks, containers used for storing a wide variety of liquids and dry substances, industrial equipment in the mining, chemical, cryogenic, food, dairy and pharmaceutical industries.

Terms of use

  • Welding in all spatial positions, except vertical down one
  • Welding is recommended to be performed at the highest possible speed without transverse oscillations of the electrode

Special properties

  • Good welding and technological properties, low spatter, easy slag removal, stable arc burning and
  • Excellent seam quality
  • When welding dissimilar steels, high crack resistance is provided and high resistance to intergranular corrosion is noted when working at a temperature of up to 300°C (572°F). As well as when welding heat-resistant stainless steels, high resistance to scale formation is provided in the operating temperature range up to 900°C (1652°F)
