Harris 0309LF5 .035" 309L Stainless Steel MIG Wire (10lb Spool)
Features:
- Similar usage as 309, but the 0.03% maximum carbon content increases resistance to intergranular corrosion
- Used for welding similar alloys wrought or cast form
- Occasionally used for welding 18-8 base metals when severe corrosion conditions exist, and, at times, welding dissimilar steels
- Packaged for portable welding machines
Normal Composition:
| Carbon | .03% max. | Chromium | 23.0-25.0% | |
| Nickel | 12.0-14.0% | Manganese | 1.0-2.5% | |
| Copper | .75% max. | Silicon | .30-.65% max. | |
| Phosphorus | .03% max. | Sulfur | .03% max. | |
| Molybdenum | .75% max. | Iron | Balance | |
| Normal Ferrite Range | 5-12 |
Typical Mechanical Properties As Welded:
| Yield Strength | 58,000 | Elongation | 40% | |
| Tensile Strength | 87,000 | Reduction of Area | 60% | |
| Charpy V | 105 ft./lb. @ room temp. | Brinell Hardness | 160 HB | |
| Rockwell B Hardness | 85 HRB |
Application:
Used to weld base metals of similar composition in wrought or cast form; also used to weld type 304 and similar base metals where severe conditions may exist. At times used to weld dissimilar steels. The lower carbon content of .03% max. will help avoid possibility of intergranular carbide precipitation.
