Strenx 700 HR W
Download data sheet
The high-strength, corrosion resistant structural steel at 101 ksi.
Strenx® 700 HR W is a hot-rolled weathering steel made for cold forming, with a minimum yield strength of 101 ksi for stronger and lighter structures.
Strenx® 700 HR W meets or exceeds the requirements of S700MC in EN 10149-2. Typical applications include a wide range of components and parts
in demanding load-bearing structures. Strenx® 700 HR W comes in coils, slit coils or cut-to-length sheets.

Thermomechanically Rolled. Strenx® 700 HR W is available in as rolled or pickled surface condition with mill or cut edge.
Strenx® 700 HR W has good welding, cold forming and cutting performance.
Strenx® 700 HR W is not suited for heat treatments at temperatures above 1076°F since the material then may lose its guaranteed properties.
The weldability of Strenx® 700 HR W is good. All the conventional fusion welding methods can be used. To obtain the same corrosion resistance in the weld as in the base metal, special filler metals should be used. Painting of Strenx® weather resistant steel is easy and will result in good paint adhesion. This can further increase the maintenance interval of the component. In order to ensure the uniform colour of the patina, all impurities must be cleaned from the steel surface. Organic impurities such as oil or protective greases must be removed by washing with suitable solvent.
Surface oxidation, oxides or rust can be removed by either shot-blasting or pickling. This will also accelerate the patina formation process. Shot-blasting is not recommended for thicknesses below 0.157". The surface of a clean weathering steel surface can be pre-patinated by allowing the surface to get wet and dryin repeated intervals.

Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the products.
Upgrading from Strenx® 700 W to Strenx® 960 W means you can improve the performance and reduce the weight of your equipment. The increase in yield strength by 37% allows for a great leap in the equipment’s load-bearing capacity.
