High Deposition Die Welding
　

The Polytrode® H.D. 500 Series
　

Polytrode® H.D. 515 (DC-RP) - A chrome/nickel/moly alloy with high tensile and yield strength for heavy buildup and joining. Uses include the repair of steel-mill slag pots, heavy machine bases and earth-moving equipment.

Rc 20-25
Specification: NA
Available forms: E , FC

　

Polytrode® 525 (DC-RP) - Higher in alloy than 515 with correspondingly higher physical properties and hardness. Polytrode® 525 displays excellent toughness while maintaining superior machining characteristics. Uses include the repair of forging-hammer bases, sow blocks, bolster plates, columns, die shanks, rams and insert holders.

Rc 25-30
Specification: NA
Available forms: E , FC

　

Polytrode® H.D. 535 (DC-RP) - A chrome/nickel/moly/vanadium alloy which has established itself in as the forging industry standard for die-block repair. Good machinability and substantially improved die life makes this alloy the number one choice for the repair and reclamation of hot-work forging dies.

Rc 34-38
Specification: NA
Available forms: E , FC

　

Polytrode® H.D. 540 (DC-RP) - A companion alloy to the Polytrode® 535 but with higher hardness and physical properties. Machinability is tough, with carbide tools recommended. Uses include overlaying of "flood" weldinf press and hammer dies, punches and inserts.

Rc 38-42
Specification: NA
Available forms: E , FC

　

Polytrode® H.D. 545 (DC-RP) - A versatile alloy for repair and reclamation of certain hammer and press dies. EDM machining is recommended. Polytrode® H.D. 545 exhibits excellent properties at high temperatures.

Rc 40-45
Specification: NA
Available forms: E , FC

　

Polytrode® H.D. 5550 (DC-RP) - An alloy designed to resist abrasion, erosion and alternate heating and cooling cycles without thermal checking, even when coolant spray is employed. Uses include overlays on hot-working extrusion dies, punches and mandrels.

Rc 46-48
Specification: NA
Available forms: E , FC
