Harbison-Fischer Polished Rods are manufactured from cold drawn, high strength carbon steel or stainless steel, machined, ground and polished to conform to H-F and API specifications.
Piston Steel Polished Rods are made from cold drawn 1045 carbon steel with a minimum tensile strength of 100,000 psi. They are recommended for moderate to heavy loads when abrasion and corrosion are not factors.
Nickel Moly Polished Rods are machined from cold drawn 4320 nickel alloy steel with a minimum tensile strength of 100,000 psi. They are recommended for moderate to heavy loads under mild corrosive conditions when abrasion is not a factor.
Tuffr® Polished Rods are made from 1045 piston steel with a minimum tensile strength of 100,000 psi and a hard, HRC 48-52 sprayed metal surface applied to the outside diameter. The sprayed metal surface length can be selected to match the pumping unit stroke length. They are recommended for abrasive and corrosive conditions under moderate to heavy loads.
Stainless Steel Polished Rods are made from type 304 stainless steel with a minimum tensile strength of 75,000 psi. They are recommended for moderate loads under all corrosive conditions when abrasion is not a factor.
