News: Tata unveil new specialist steel grades


Tata Steel's South Yorkshire based Speciality Steels business has unveiled a new family of steel grades for the oil and gas market.

With enhanced properties tailored to work in the most demanding downhole tool and completion equipment environments, the new HyPer family of steel grades are manufactured at Speciality Steels' production facilities in South Yorkshire, which has been at the forefront of producing steel for the oil and gas market for more than 60 years.

Over 2,000 people are employed by the company in South Yorkshire where sites like Stocksbridge in Sheffield and Aldwarke in Rotherham, focus on exceptional high-value products and sectors. Investment in 2005 saw the Rotherham site at Aldwarke become the focus for steel making, casting and rolling of specialist steels. The steel is manufactured from recycled material at the Rotherham site before undergoing further refining at the Stocksbridge plant or the Thrybergh Bar Mill to improve the quality.

The sites have been benefiting from significant investment and a focus on a high-quality portfolio programme. The European operations are pursuing an objective of supporting customer success in their own markets through product and service improvement. Over 100 new products have been added to the Indian-owned steelmaker's portfolio this year and the higher proportion of differentiated products in total sales is being maintained. Tata believes that the launches are enabling the company increasingly to take leadership positions in key areas of the markets it serves.

The European manufacturing facilities produce a wide range of products for offshore applications; from line pipe to transport oil and gas across the deepest waters in the Gulf of Mexico through to high strength engineering steels delivering longer life usage in the deepest wells. Tata's speciality steels are used in a diverse range of applications within the Oil and Gas production industry and are incorporated into turbines, pumps, valves, process plant and all manner of other machinery. They are found in components such as gears, shafts, fasteners, flanges and bearings.

Ian Davidson, sales manager for Oil and Gas at Tata Steel, said: "Each of the three grades of steel within the HyPer family has been developed in response to specific customer requests. HyPer30 is a low alloy steel with improved mechanical properties and enhanced corrosion resistance compared to standard grades for use in mud motors while HyPer30V is a high strength alloy steel which still retains its market-leading impact properties. HyPer45 is an enhanced alloy steel grade which combines high strength with high toughness at sizes up to 12" diameter.

"The improved performance envelope of all the HyPer grades compared to more traditional variants gives our customer base the opportunity to either rationalise their stock profiles or simply deploy these grades into more challenging operating conditions."

Andrew Parker, commercial director at Speciality Steels, added: "The introduction of the HyPer grade family builds on a series of initiatives which our dedicated oil and gas team has made. These developments have included the introduction of imperial (inch) size rollings on the Stocksbridge mill in the UK, the launch of oil and gas grades in sizes less than 3in and improved central soundness guarantees across our product range.

"The aim of all these initiatives is to supply the market with the improved products it demands while looking to reduce their total costs."

The new range of steels has been showcased at this week's Offshore Technology Conference at Reliant Park in Houston, Texas.
