Straightening of ship hull structure made of 316L stainless steel - microstructure of water cooled material
Opis
The AISI 316L type steel belongs to the group of chromium-nickel stainless steels. They are determined according to European standards as X2CrNiMo17-12-2 and belong to the group of austenitic stainless steels. Steels of this group are used for elements working in seawater environments, for installations in the chemical, paper, and food, industries, for architectural elements, and many others. The chemical composition of corrosion-resistant austenitic steels provides them with an austenite structure that is stable in a wide temperature range, under appropriate conditions for heating, soaking, and cooling. 316L steel plate was subjected to a technological treatment of hot straightening with an oxy-acetylene torch, which is not commonly used for this type of steel, mainly due to the lack of objective assessment of whether the austenitizing temperature has been achieved and the stability of the heat treatment process is ensured. The single-phase structure of austenite with high corrosion resistance, without precipitation of carbides, steel is obtained by supersaturation in water from 1100 °C. The purpose of the performed research was to determine the usefulness of the flame straightening process for a ship structure made of 316L steel.
Eight test plates were provided for testing: two reference ones made of material not subjected to flame straightening (reference material), three straightened and naturally cooled ones), and three straightened and water-cooled ones. All panels had dimensions of 300×450 mm and a thickness of 10 mm. Straightening was carried out using triple flame burners. The straightening direction was perpendicular to the rolling direction.
This dataset contains photographic documentation of microstructure for water cooled material.
