Tenaris TN 95EY steel for Canadian operators: materials and sour service notes
Reviewed by Joe Ashwell

First reported on MINING.com
30 Second Briefing
Tenaris has begun domestic production of its proprietary TN 95EY steel grade at its Sault Ste. Marie Industrial Centre, the only North American facility manufacturing both seamless and welded pipe under one roof, targeting high-pressure, high-temperature sour service wells in the Montney and Duvernay formations. The company has invested over C$355 million in Canada since 2020, including a C$306 million modernisation and expansion programme announced in May 2026 with federal and Ontario government support. Local TN 95EY output required retooling existing processes plus comprehensive per-pipe testing and traceability, tightening supply chains for Canadian oil and gas operators.
Technical Brief
- Bringing TN 95EY into Canadian production required extensive collaboration to adapt existing manufacturing processes and manage the comprehensive testing and tracking required for each pipe, it said.
Our Take
Tenaris’s more than C$355 million in Canadian investments since 2020 places it at the upper end of energy-materials capex in our Materials coverage, signalling that Western Canadian oil and gas basins like Montney and Duvernay remain strategic enough to justify onshore tubular manufacturing rather than relying on imports.
With oil and gas dominating the 137 keyword-matched pieces in our database, Tenaris Canada’s product development for Western Canadian operators indicates that service and materials suppliers are competing on basin-specific steel grades and reliability, rather than just price, to secure long-term contracts in these mature plays.
