Cromarod 309L is a rutile flux coated electrode which deposits a 23%Cr /
13%Ni austenitic stainless steel weld metal. The high alloy content and
ferrite level enable the weld metal to tolerate dilution from mild and
low alloy steels without hot cracking or brittle structures.
– Dissimilar joints between stainless and mild or low alloy steels. – Buffer layers on mild and low alloy steels prior to overlaying with Cromarod 308L or Cromarod 347. – Interface runs in clad steel joints. – Joining of clad steels and dissimilar joints between stainless and mild or low alloy steels. – Welding of similar composition 309 type austenitic stainless steels. – Joining ferritic-martensitic 410 and 430 type stainless steels.
