Durehete 1055 Fasteners

1% CrMoV Steel for bolting applications up to 570°C made in the UK by Hague Fasteners since 1971.

Durehete 1055 has been the ultimate choice material for high temperature applications up to 570°C for decades and Hague Fasteners have manufactured and supplied super critical turbine studs and capnuts for every British Power Station over their 45 year plus history.

Durehete 1055’s high temperature performance has been proven in these 45 plus years and the Durehete 1055 is now the only mainstream remaining Durehete grade surviving in production following the demise of Durehete Nut Steel (DNS) Durehete 900 and Durehete 950. The T41 Durehete 1055 specification was the original equipment specification for Alstom (GEC) and Siemens (Parsons) powerplants in the UK.
