| Özet: | Title screen The reasons for the decrease in the operational resistance of high-pressure metal hoses made of austenitic steels are considered. The main cause of damage to metal high-pressure hoses was revealed, namely, the low performance of the metal protective braiding under the influence of an unfavorable environment. It has been established in the work that in the initial state the wire made of AISI 201 steel has a high strength (σ0.2 = 1370 MPa and σT = 1650 MPa) and has relatively low plastic characteristics (δ = 15 % и ψ = 40 %), since up to 40–60% deformation martensite is present in its structure. The resistance of steels of the austenitic class AISI 201 and AISI 316 to intergranular corrosion has been investigated. The effect of heat treatment on the mechanical and plastic properties of wire samples of ø made of AISI 201 steel has been investigated. Optimal heat treatment modes have been determined that increase the durability of the braid in an unfavorable environment and, consequently, the operational durability of metal hoses in general Текстовый файл AM_Agreement |
