T45 Stainless Steel Tube

Affording design engineers more options.


T45 is widely used in the aerospace sector, where high tensile and yield strength characteristics are required.

T45 high strength carbon-manganese stainless steel tubes offer excellent strength to weight ratios.


T45 carbon-manganese stainless steel provides excellent strength to weight ratios, enabling engineers to design products with thinner-walled tubing without compromising overall strength. T45 is widely used in the aerospace sector, where high tensile and yield strength characteristics are required, particularly in pilot ejector seats, as the alloy withstands the higher G forces incurred during flight without snapping or splitting. The material is easily welded and formed and finds extensive use in airframes and aerostructures.


Longstanding History

The product has been on the market for more than 60 years and is highly suitable for applications where reduction in weight is a primary consideration but not at the expense of overall strength. The motorsport sector serves as another market example where the alloy finds use in roll cages, chassis and suspension parts.
