Product Description

National Engineering Works manufactures High Tensile Alloy Steel Calibrated Round Link Chains ( Up to 50 mm Dia) for Bucket Elevators (IS 6216:1982 & IS 3948:1986).These chains are specially case hardened to withstand continuous corrosion owing to handling of abrasive particles. High Tensile Link Chains for Bucket Elevator (as per DIN 764 & DIN 766) are manufactured from premium grade refined Ni-Cr-Mo Alloy Steel or Mn Steel.These chains are gas carburized to a case depth of 0.01 mm ensuring uniform surface hardness.Link Chains are calibrated and supplied in matched pairs and occasionally smeared with protective coating for anticorrosion resistance. Corresponding Chain Bows (U-Links/ U Bolts/ Bucket Links/ Chain Brackets) as per IS 10131 & DIN 745 for Bucket Elevator, in which wearing portion at the crown of the shackle is specially heat-treated to a hardness of 55-57 HRC to a case depth of 0.1 mm.The U Links and Chain Shackles are supplied with carbon steel distance plate, hex nuts and spring washers.
