PHILSTAIN 309MoL

 

AWS Specification : AWS A5.4 E309MoL - 16

JIS Specification: D309MoL-16

DIN Specifiction: DIN EN 1600-97 : E 23 12 2 L R 32

 

I. APPLICATIONS:

Build up welding of Cr-Mo steel or carbon steel.

Welding of AISI (SUS) 316 or AISI (SUS) 316L to carbon steel.

Clad steel side welding to AISI (SUS) 316 or AISI (SUS) 316L.

II. DESCRIPTION:

PHILSTAIN 309MoL is a lime-titania type electrode for all-position welding, which have good usability and good weldability. Good resistance against dilute sulfuric acid compared with that of PHILSTAIN 309MoL. Weld metals provide excellent corrosion resistibility and heat resistibility in the as-welded condition. As PHILSTAIN 309MoL is of low carbon content, it can be used for welding of extra-low carbon stainless steel which contains Mo and for under laying of mother plates which contain considerably high carbon content.

III. NOTES ON USAGE:

• Keep the arc as short as possible and choose the welding current as low as possible.

• Weaving width should be within two and a half times of electrodes diameter.

• When the electrodes haveabsorbed moisture, dry them at 250-300ºC for 60-90 minutes before use.
