Tata Steel’s Speciality Steels business unveiled an enhanced version of its existing 4145H modified alloy steel grade, which combines high strength with toughness making it ideal for use in demanding downhole tool and completion equipment environments. This improved bar product grade is manufactured at Speciality Steels’ production facilities in South Yorkshire, UK.
Mike Jeglic, Tata Steel Sales manager for Oil and Gas in Houston, said, “This enhanced grade, which combines high strength (130 ksi yield) with high toughness (42J at -20°C) at sizes up to 12″ diameter, has been developed in direct response to customer feedback. The improved performance envelope of this enhanced offering compared to more traditional variants of 4145H modified grades gives our customer base the opportunity to rationalise their stock profiles as well as the opportunity to deploy this alloy in more challenging operating conditions.”
Richard Lowe, general manager, Speciality Steels Americas, said, “The introduction of the grade is part of a series of ongoing initiatives that our dedicated oil and gas team has delivered in the past few months in response to customer feedback. These developments have included the introduction of imperial (inch) size rollings on the Stocksbridge (UK) mill, the launch of oil and gas grades in sizes less than 3” and improved central soundness guarantees across our product range.”
