INFLUENCE OF DIFFERENT CHEMICAL COMPOSITION ON RESISTANCE OF TRIP 800 STEEL TO HYDROGEN EMBRITTLEMENT

Popis výsledku v původním jazyce

Resistance to hydrogen embrittlement was studied for 3 variants of TRIP 800 steel, based on C-Mn-Si; C-Mn-Si-Al and C-Mn-Si-P, by performing tensile tests on electrolytically hydrogenated specimens. The specimens were prepared from laboratory heats, ingot weight was 150 kg. The ingots were forged into slabs, which were rolled into sheets 3 mm thick and subsequently cold-rolled to the thickness of 1.5 mm. The sheets were then subjected to two-stage annealing: the sheets were first annealed in the intercritical region, cooled rapidly, and annealed in the bainitic transformation region. All the variants examined met the requirements for the TRIP 800 steel. The yield strength laid in the range of 420-490 MPa, the tensile strength was in the range of 880-950 MPa. The residual austenite content was 9-13% in dependence on the variants. Specimens for the tensile tests serving for examination of their resistance to hydrogen embrittlement were obtained by hydrogenation in dilute sulphuric acid f
