FILLER METALS

™
ProStar Stainless Steel Wire & Rod

For stainless steel fabricators, ProStar stainless steel
wire and electrodes are designed to provide good
corrosion and crack-resistant welds with excellent
welding characteristics and superior wetting.

APPLICATIONS SPECIFICATION
• Chemical • AWS 5.9, ASME SFA 5.9
• Construction
• Food Handling
• Petrochemical
• Pharmaceutical
• Structural

MIG AND TIG CLASSIFICATIONS
Filler Metals* Base Material
308L, 308LSi 302, 304, 304L
309L, 309LSi Dissimilar base metals
(i.e., mild steel to stainless steel)
316L, 316LSi 304, 304L, 316, 316L
* High silicon reduces grinding requirements, but may not be suitable
for some military applications or when welds are highly polished.
