Abstract

A structural low alloy manganese cast steel having improved hardness and wear resistance, and articles made therefrom are disclosed. In particular, after conventional bulk quenching followed by tempering, the disclosed steel has a hardness of approximately 418 and 512HB, suitable for use in railroad engineering, particularly for the manufacture of freight car components, such as friction wedges. The improved hardness and wear resistance of the components made of the steel of the invention results in improved service life, particularly for the service life of the friction wedge/friction plate friction pair, without a significant increase in the manufacturing costs of the components.

Description

Alloy cast steel and product thereof
Technical Field
The invention relates to metallurgy, in particular to structural alloy cast steel suitable for railway engineering, in particular to railway vehicle manufacturing industry.
Background
With the development of railway engineering, there is an increasing interest in developing materials for improved structures with improved reliability and durability, which are also relatively inexpensive. These materials are useful in the construction of ground railroads and in the manufacture of parts of railway vehicles. Furthermore, in terms of maintenance reliability, the most stringent requirements are steels for railway rails and parts of freight and passenger trucks, particularly parts requiring durability and wear resistance, such as truck center plate discs, wheels and axles, friction wedges and friction plates.
The friction wedge of a truck is part of a shock absorber of a car, which provides a stable and smooth movement during operation. Currently, there are many different variations of friction wedges made of different materials. For example, the development of compositions and techniques for specially modified cast iron for railway rolling stock friction devices with higher working durability for friction wedges made of grade 35[ technical specification 3183-: scientific doctor academic thesis: 05.16.01-Moscow, 2014 ], 20GL, 20FL, 20GTL grade steel [ Bangdlacco A.F., Gordlacco A.A., Fielding V.M., Botz A.I., volumetric surface hardening// Vestnik VNllZhT of steel friction wedges, 2010, Vol.3, p.43-45 ]. However, a common disadvantage of friction wedges made of said materials is that the hardness and wear resistance of the wedge are insufficient for trucks with loads per axle exceeding 25 tf.
It is therefore an object of the present invention to provide an alternative construction material suitable for manufacturing a friction damper absorbing friction force vibrations, which material has improved strength and durability and at the same time is relatively inexpensive.
Disclosure of Invention
In the present invention, the above problems are solved by providing a new alloy cast steel composition, wherein the new alloy cast steel composition has the following elemental contents (wt.%):
Figure BDA0002921646890000021
wherein the composite alloy coefficient CE of the steel calculated as CE ═ C + (Mn + Si)/6+ (Cr + Mo + V)/5+ (Ni + Cu)/15 is not less than 0.68 wt%.
Thus, as a result of extensive studies, the present inventors have found that a steel having the above-described narrow carbon and manganese content ranges, specific chromium, aluminum and vanadium content ranges, and more severe phosphorus, sulfur, copper and nickel content ranges and specified values of the calculation coefficient (i.e., the complex alloy coefficient CE) introduced by the inventors has significantly improved hardness and wear resistance even without using advanced quenching treatment, unlike 30GSL grade steel in the background of the invention. In particular, higher hardness and wear resistance can be obtained with conventional bulk quenching and subsequent tempering treatments, and therefore the increase in the manufacturing costs of such steels is insignificant compared to the prior art materials; in particular, the above cost is increased by 3-7% compared to 20GL grade steel, for example.
The technical effect of the invention is therefore to improve the hardness and wear resistance of articles made of the steel of the invention without significantly increasing their manufacturing costs. The other technical effect is that the hardness and the wear resistance of the surface of the freight car friction wedge are improved, and the service life of the friction wedge/friction plate friction pair is prolonged. Yet another technical effect of the present invention is to avoid the use of expensive machining methods for the steel, but to do so by simple bulk quenching and subsequent tempering, while at the same time improving hardness and wear resistance.
The invention also provides articles made from the steels of the invention. According to a particular embodiment, the article is a friction wedge for a truck.
Drawings
Fig. 1 shows the surface hardness of a workpiece (friction wedge made of a steel according to the invention) obtained after a heat treatment (bulk quenching with tempering) as a function of the complex alloy coefficient CE of the steel, calculated as follows:
СЕ＝C+(Mn+Si)/6+(Cr+Mo+V)/5+(Ni+Cu)/15.
Detailed Description
In order to compare the hardness values of the samples made of steel according to the invention with those of the friction wedges made of prior art material, a comparison of the values of the hardness of the gray cast iron grade 25 and the steel sample grade 20GL, comparative tests were carried out, the results of which are shown in Table 1 below:
TABLE 1
Hardness, HB
Steel of the invention 418-512
Grade 25 gray cast iron 197-260
Steel 20GL 140-180
The brinell hardness test of the samples was performed as follows:
GOST 9012-59: metal, brinell hardness method.
