Abstract Outokumpu Moda 439/4510 is a titanium-stabilized 17% chromium ferritic stainless steel that exhibits improved corrosion resistance, formability, and weldability when compared to Outokumpu Moda 430/4016. It is best suited for mildly corrosive environments. Because of its titanium alloying, Outokumpu Moda 439/4510 can be welded in all dimensions without becoming susceptible to intergranular corrosion. It is possible to use Outokumpu Moda 439/4510 at elevated temperatures, for example the cold end of automotive exhaust systems. This datasheet provides information on composition, physical properties, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-1341. Producer or source: Outokumpu Oyj.

Ct Analysis

In the present investigation, thin sheets of stabilized and unstabilized ferritic stainless steel were welded in butt joint configuration using irradiation of a 1070 nm fiber-laser. Using optical microscopy, the microstructural evolution upon alternating heat input was characterized. In addition to that, hardness and tensile tests were carried out on the specimens. Detailed focus was given to the intergranular corrosion properties, which were investigated on basis of the Strauss test with different times of exposure to the corrosive environment. Following these tests, the mechanical properties of the joints were characterized using tensile tests. A combination of the latter with an inspection by μ-CT analysis allows for the proposition of an intergranular corrosion rate with regard to the degradation of the joint strength.
