high hardness non magnetic stainless steel drill collar for sale
All our Drill Collars and Non-magnetic Drill Collars are manufactured in accordance with API 7-1 Standard as required by the oil and gas industry. To deter stress corrosion cracking, all of our Non-Mag material has the inter diameter treated with a shot peening operation. This compresses the inside diameter, and has been very successful in preventing stresses from forming while drilling in chloride or H2S atmospheres (sour gas) drilling environments.
