“…The problem of inaccurate dimensions of the angle of a given part is proposed to be solved with the introduction of an elastic element into the die [20][21][22]. The new method is suitable for different materials with the same angle [7,17].…”

The process of less than 90 degrees angle bending is presented in this article. Elastic-plastic deformation took place in the sample. After removing the force, the effect of elastic spring-back occurs – the angle of the part is increased by a value that depends on many parameters. The usage of an elastic element in the stamp allows us to change the angle of spring-back. This is happened doe to adjusting the height of the press stroke. This allows us to produce parts with accurate dimensions.

“…In addition, they do not provide high air-tightness of products due to the tendency to porosity and film formation. These steels tend to form a developed cast dendritic structure that has a negative effect on the cold resistance of castings [22].…”

This article presents the results of a study of martensitic steels. Studied steels: OZH9K14N6MZD, 12X18N10TL, 07X13G28ANFL. The object of the study was the optimization of properties for use in cryogenic technology. The purpose of the study is to increase the strength and service life of products for various purposes. The destruction of steel 12X18N10TL and 07X13G28ANFL was investigated. It has been established that 07X13G28ANFL steel is more preferable for cryogenic use and is recommended by the authors.

“…However, in spite of a great number of published papers [40][41][42][43][44], it should be noted that reliable approaches to the choice of proper bainitic structure, which can provide both improved strength properties and high ductility and toughness, have not been developed yet. Furthermore, there is no single classification system and commonly accepted interpretation of morphological characteristics of bainitic structures, which are formed during accelerated cooling in low carbon alloyed steels, and their influence on the properties [45][46][47][48]. Different terms can be used to identify the same structure, and vice versa, i.e., the same term can be used to identify different structures.…”

Development of Alloyed Pipe Steel Composition for Oil and Gas Production in the Arctic Region

Gas and oil pipelines for the Arctic region must sustain low temperatures and high internal pressures of a corrosive active medium. Generation of new steel compositions for oil and gas pipelines is an urgent issue in order to ensure their high reliability. Low-carbon steels with a ferritic–pearlitic structure are normally used in pipe production, but they are unable to cope with increased market demands. The main objective of this study is to investigate the influence of the cooling rate on the structure and morphological characteristics of bainite, which determines the exploitation properties of the pipe steels. Dilatometric tests were carried out using a Gleeble 3500 complex. Optical microscope and scanning electron microscope analysis, with the computer image analysis system Thixomet PRO, were used to study the microstructure of steel. Hardness was measured in accordance with ASTM E-384. Morphological characteristics of bainite components that were formed at various cooling rates from 0.05 to 100 °С/s were defined. The novel result of this study is the continuous cooling transformation diagram of undercooled austenite of the steel containing 0.062% С; 1.80% Mn; 0.120% Mo; 0.032% Cr, 0.90% Ni and other elements (Al, Cu, V, Nb, Ti).
