Standard Square Kelly is made from AISI 4145H alloy steel according to API Spec7-1. We can offer Square Kelly and Hexagonal Kelly. Kelly's ends drive cross-section and joint are all processed and tested in terms of API Spec7-1.

It is formed through hot forging and fully heat-treated by intermediate frequency induction heat treatment or 20m horizontal optical resistance furnace. Threads can be phosphated, copperized or cold worked.

Features:

1. We can manufacture square kelly and hexagonal kelly as per requirements of customers.

2. They are made of AISI 4142H-4145H forged or rolled alloy structural steel. Quenching plus tempering thermal treatment will be conducted over the whole length. Its Brinell hardness can reach 285-341 on the basis of such thermal treatment. Charpy impact energy: 54J. The formulated process can ensure that the misalignment of the hole reaches the standard wall thickness.
