The high-strength structural steel at 900 MPa
Strenx® 900MC is a hot-rolled structural steel made for cold forming, with a minimum yield strength of 900 MPa.
Strenx® 900MC meets and exceeds the requirements of S900MC in EN 10149-2. These cut-to-length sheets feature excellent thickness accuracy and surface quality in relation to strength level, providing an outstanding finish to the final products. Typical applications include advanced lifting devices and lighter transport solutions and components.

The mechanical properties are tested in the longitudinal direction.
1) If ReH is not applicable then Rp0.2 is used.
2) For both longitudinal and transverse direction.

Strenx® 900MC has good welding, cold forming and cutting performance.
Strenx® 900MC is a cold forming steel not suited for heat treatments at temperatures above 400°C since the material then may lose its guaranteed properties.
For information concerning fabrication, see SSAB´s brochures on www.ssab.com or consult Tech Support.
Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the products.
Upgrading from Strenx® 900MC to Strenx® 960MC means you can improve the performance and reduce the weight of your equipment. The increase in yield strength allows for a substantial increase in the equipment’s load-bearing capacity.
