Class: E309MoL-16

AWS: A5.4

Conforms to Certification: AWS A5.4        ASME SFA A5.4

Weld Process: Shielded Manual Metal Arc

AWS Chemical Composition Requirements
C = 0.04 max Si = 0.90 max
Cr = 22.0 – 25.0 P = 0.04 max
Ni = 12.0 – 14.0 S = 0.03 max
Mo = 2.0 – 3.0 Mn = 0.5-2.5
Cu = 0.75 max

Application
Type 309MoL-16 is designed for applications requiring molybdenum with a standard 309 analysis except for a lower carbon limit. It is used primarily for welding type 316 clad steels, or welding molybdenum-containing austenitic stainless steel to carbon steel. Service temperature must be less than 600F.
