Postalloy® 215HD Tubular Electrode

Postalloy® 215HD is a chromium carbide tubular hardface electrode for hardfacing low carbon mild and alloy steels, manganese steel, stainless steel and cast iron. It's tubular structure permits higher travel speeds and much higher percentages of carbide forming elements contained in the core than with ordinary flux-coated electrodes. Due to its unique tubular design, Postalloy® 215HD offers very smooth operational characteristics and is over 90% efficient. All of the 1/4" (6.4mm), 3/8" (10mm) and 1/2" (12.7mm) diameters will fit standard electrode holders.

• Easy out-of-position weldability with the 1/4" (6.4mm) diameter
• Excellent AC or DC operation, even on a "buzz box"
• High metal recovery - no slag to chip
• Low amperage and high deposition rates - up to 3 times faster than ordinary electrodes
• Moisture resistant coating, even under severe weather or high humidity.

Weld deposit chemistries consist of chromium carbides combined in such a way as to produce extremely good abrasion resistance coupled with mild to moderate impact resistance. Deposits take on a high polish to resist sliding particle abrasion and will maintain good hot hardness up to 1000 °F (538 °C).
