Technical data sheet for Hobart mild steel and low alloy welding electrodes, including classifications, storage, chemical composition and mechanical properties.
This data sheet provides detailed specifications for Hobart's range of mild steel and low‑alloy welding electrodes. It lists AWS classifications, recommended storage and re‑conditioning procedures, chemical composition of the weld metal deposit, and mechanical properties for each electrode model.
The document also includes packaging information, approvals and conformances, and recommended operating amperage ranges for various electrode diameters. It serves as a reference for welders, specifiers and distributors needing precise product details.
| Pipemaster Pro‑60 Tensile Strength | 76,000 psi (527 MPa) |
|---|---|
| Pipemaster Pro‑60 Recommended Amperage (1/8") | 65‑130 A |
| Hobart 335A Tensile Strength | 82,000 psi (563 MPa) |
| Hobart 447A Tensile Strength | 74,000 psi (510 MPa) |
| Rocket 7024 Tensile Strength | 76,000 psi (527 MPa) |
Mild steel electrodes should not be stored above 130 °F; recommended oven temperatures are 100 °F–130 °F for certain classes.
Pipemaster Pro‑60 uses Direct Current Electrode Positive (DCEP).
Low‑alloy electrodes are classified under AWS designations such as E7018, E8018, E9018, E10018, etc.
Damaged cartons should be removed because they allow damp air to enter, which can lower electrode quality.
