Abstract

Toplotna prevodnost in ostale toplotne lastnosti jekla so pomembne pri njegovi uporabi in pri načrtovanju ter izvedbi njegove toplotne obdelave. V okviru diplomskega dela smo izmerili oziroma določil toplotne lastnosti jekla AISI 316L (toplotno prevodnost, specifično toploto in temperaturno prevodnost), izdelanega v proizvodnih obratih največjega slovenskega proizvajalca jekla, s posebnim poudarkom na njegovi toplotni prevodnosti v t.i. dobavljenem stanju jekla in po izvedeni toplotni obdelavi, ki vključuje raztopno žarjenje in gašenje v vodi. Izvedli smo meritve, analizo in vrednotenje toplotnih lastnosti na napravi za določevanje toplotnih lastnosti Hot Disk TPS 2200 v skladu s standardom ISO 22007-2 pri temperaturi okolice. Srednje vrednosti toplotne prevodnosti jekla 316L v t.i. dobavljenem stanju je 13,85 W/(m·K), po izvedeni toplotni obdelavi pa je za približno 0,2 W/mK višja in znaša 14,04 W/(m·K)

Secondary title: thermal conductivity of stainless steel AISI 316L
Secondary abstract: The thermal conductivity and other thermal properties of steel are important in its use and in the planning and execution of its heat treatment. As part of the thesis, we measured or determined the thermal properties of AISI 316L steel (thermal conductivity, specific heat and temperature conductivity), produced in the production facilities of the largest Slovenian steel producer, with a special emphasis on its thermal conductivity in the so-called delivered condition of the steel and after heat treatment, which includes solution annealing and quenching in water. We performed measurements, analysis and evaluation of thermal properties on the device for determining the thermal properties of Hot Disk TPS 2200 in accordance with the ISO 22007-2 standard at ambient temperature. Average values of thermal conductivity of steel 316L in the so-called in the delivered state it is 13.85 W/(m·K), but after heat treatment it is about 0.2 W/(m·K) higher and amounts to 14.04 W/(m·K)
