POSTALLOY 214 is a high chromium carbide hardfacing electrode for high abrasion and mild impact applications. Deposits take on a high polish, producing excellent frictional and sliding abrasion resistance. Use on carbon and alloy steels, stainless steels and cast iron.
Heat and Corrosion Resistant - Corrosion resistance is equal to straight chromium steels and it retains its hardness up to 1000°F(538°C).
POSTALLOY 214 offers good out-of-position welding characteristics on either AC or DC. Fast deposition rate and easy slag removal. It produces minimum dilution for high first past hardness and deposits are extremely smooth - almost ripple free.
POSTALLOY 21 is a “self-hardening" wear resistant overlay engineered for abrasion and abrasion combined with medium impact. The alloy chemistry provides good resistance to spalling and chipping while the special low hydrogen coating minimizes dilution and helps to eliminate underbead cracking. Use on carbon and low alloy steels, It can be used out-of-position and can be used with all types of AC or DC equipment.
POSTALLOY 27 is a build-up electrode in the machinable range of hardness providing wear resistance that is far superior to low and medium carbon steel and low alloy steels. Deposits are extremely tough and have a high resistance to impact and deformation and are not subject to spalling or roll-over. In addition, deposits are dense, crack-free and porosity-free.
Ideal for use on manganese steel. Under severe impact, such as hammering or pounding, deposits quickly become tougher and harder, and will not spall or mushroom. POSTALLOY 205 may be used alone, as a combination build-up and hardfacing alloy, or used as a build-up and cushion prior to overlaying with a more abrasion resistant alloy, such as 213 or 214. POSTALLOY 205 is an all-position electrode for joining or overlaying for high impact. It operates on either AC or DC reverse; the arc is smooth and stable with low spatter loss. Slag removal is easy.
POSTALLOY 215HD hardfacing electrodes, available in 1/4"(6.0mm) and 1/2"(12.5mm), are a unique concept in hardfacing technology. They are tubular, permitting higher travel speeds and much higher percentages of carbide forming elements contained in the core than with ordinary flux-coated electrodes. 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). Due to its unique tubular design, POSTALLOY 215HD offers very smooth operational characteristics. Both the 1/4" and 1/2" diameters will fit standard electrode holders. Other outstanding features are:
* Easy out-of-position weldability with the 1/4" diameter.
* Excellent AC or DC operation, even on a "buzz box".
* High metal recovery - no slag to chip. POSTALLOY 215HD is over 90% efficient.
* Low amperage - 1/4"(6.0mm) from 80 amps, 1/2"(12.5mm) from 180 amps.
* High deposition rates - up to 3 times faster than ordinary electrodes.
* Moisture resistant coating, even under severe weather or high humidity.
POSTALLOY 206HD is a high chromium, nickel, moly alloy electrode that produces deposits with excellent strength and elongation, combined with a high degree of toughness. Weld deposits work-harden in service and provide outstanding impact resistance. The austenitic structure of the weld deposit provides very good corrosion resistance. It's versatility allows it to be used for joining, as well as a cushion layer prior to hardfacing with a harder, more wear resistant alloy. Use on carbon and alloy steels, stainless and manganese steels and joining dissimilar combinations.
POSTALLOY 301 is a high strength, ductile, crack resistant welding alloy specifically designed for welding problem steels such as, low alloy, high carbon or crack sensitive tool steels. Ideal for welding dissimilar steels - low alloy, spring steels, carbon steels, tool steels.
EXCELLENT JOINING CHARACTERISTICS - With the combination of balanced alloy chemistry and high strength, crack resistant weld deposits, the capability to weld dissimilar problem steels is outstanding.
CARBON HAS NO ADVERSE AFFECTS - Carbon, the cause of most problems associated with weld cracking and hard spots, is rendered harmless.
ACTS AS A SHOCK ABSORBER DURING OPERATION - Since POSTALLOY 301 does not respond to heat-treatment and remains ductile, it has the ability to withstand heavy impact or shock loading.
Postalloy Super 35
POSTALLOY SUPER 35, a general purpose mild steel electrode, simplifies all welding applications involving mild steel and provides the maintenance welder with a tremendous degree of versatility. It is remarkably easy to use even on an AC “buzz box”. Just strike the arc and let it go to work.
POSTALLOY SUPER 35 is easy to use in all positions and features instant strike and restrike characteristics. The arc is smooth and the slag is self-releasing. Low smoke volume makes it ideal for confined or poorly ventilated areas. Can be used as a contact or “drag” electrode. May be used at the lowest possible amperage to prevent burn through on thin sheet metal. High amperage capability for deep penetration when welding through rust, paint, grease and dirt. Deposits on galvanized steels with little or no burning of the surrounding galvanized coating. Leaves no porosity. Electrode may be bent without the coating popping off when welding hard to reach corners. High degree of moisture resistance.
