Strength Improvement

The impact of microstructure evolution on mechanical properties in superduplex stainless steel UNS S32750 (EN 1.4410) was investigated. To this end, different thermomechanical treatments were carried out in order to obtain clearly distinct duplex microstructures. Optical microscopy and scanning electron microscopy, together with texture measurements, were used to characterize the morphology and the preferred orientations of ferrite and austenite in all microstructures. Additionally, the mechanical properties were assessed by tensile tests with digital image correlation. Phase morphology was not found to significantly affect the mechanical properties and neither were phase volume fractions within 13% of the 50/50 ratio. Austenite texture was the same combined Goss/Brass texture regardless of thermomechanical processing, while ferrite texture was mainly described by α-fiber orientations. Ferrite texture and average phase spacing were found to have a notable effect on mechanical properties. One of the original microstructures of superduplex stainless steel obtained here shows a strength improvement by the order of 120 MPa over the industrial material.

Superduplex Stainless Steel

Abstract Ferralium 255-SD50 has much higher strength than other commercially available superduplex alloys. Ferralium 255 is the original superduplex stainless steel, noted for its unique combination of mechanical properties and resistance to corrosion, erosion, and cavitation. It has especially low impurities giving improved corrosion resistance, and it is used extensively in the offshore and chemical industries. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on forming and machining. Filing Code: SS-1133. Producer or source: Langley Alloys.

ABSTRACT The tests results of superduplex stainless steel welded joints made with a different heat input, using automatic submerged arc welding (SAW) and semi-automatic flux-cored arc welding (FCAW) have been presented. Metallographic examinations, the measurements of the ferrite content, the width of the heat affected zone (HAZ) and the hardness of the welds in characteristic areas have been performed. Significant differences in the amount of ferrite in the weld metal and in the heat affected zone microstructure of joints were found.

The mechanical properties of four cast high-strength steels, 4340, 15-5 PII stainless steel, and two maraging steels were examined. To provide a direct comparison with wrought steels split heats were prepared in which part of each heat was sand cast and the balance was forged and hot-rolled to plate. The KIc properties of the castings were comparable to the plate properties. Limited tests indicated that the cast steels also had reasonably good fatigue and stress corrosion cracking resistance. The castings showed surprisingly low Charpy values, which was attributed to notch acuity due to the more heterogeneous nature of the fractures in the cast structures. The overall results suggest that cast high-strength steels had satisfactory toughness and could be used in many applications.
