TTSTE 355 Z3
Our steel, TTSTE 355 Z3, is a product of a long and good cooperation with the largest suppliers in the Norwegian offshore industry.
A common requirement in the North Sea and the Norwegian Sea is that the toughness of the steel must be maintained down to minus 46 degrees Celsius. Further north the requirements will probably increase and you can talk about temperatures down to minus 60 degrees.
We are doing very well today’s very strict toughness requirements, set at minus 46 degrees. We have very good tests right down to minus 60. It is Grotnes Steel that customers demand, and that name identifies everyone in the company with us. Therefore it is quite natural that it is also our company name.
