PRODUCT NAME

AWS CLASS

APPLICATIONS

Murex? 308L

ER308
ER308L

For joining common austenitic stainless steel grades referred to as "18-8" steels
All-position TIG welding
ASTM A240 Types 302, 304 and 304L
ASTM A743, A744 Types CF-8 and CF-3

Murex? 309L

ER309L
ER309

For joining higher alloyed austenitic stainless steels.
Can also be used on "18-8" steels, since it overmatches the corrosion resistance, if the weldment will not be exposed to temperatures of 1000 to 1700° F (538 to 927° C)
All-position TIG welding.
ASTM A240 Type 309S
ASTM A743, A744 Type CG-12

Murex? 316L

ER316L
ER316

For joining and cladding 316L joints and overlays. Can also be used on "18-8" steels
All-position TIG welding
ASTM A240 Types 316 and 316L.
ASTM A743, A744 Types CF-8M and CF-3M

Murex? 316LSi

ER316Si
ER316LSi

For joining and cladding 316L joints and overlays. Can also be used on "18-8" steels
ASTM A240 Types 316 and 316L
ASTM A743, A744 Types CF-8M and CF-3M
All-position welding.
Intended to be used with argon/oxygen blend or helium-rich shielding gas mixtures
Should not be used in urea manufacture, as this environment will attack the ferrite
