Composition and properties
Steel 65S2VA produced according to technical requirements GOST 14979, is a high-quality high-carbon spring steel containing an increased amount of tungsten. The steel composition specified in the table below:
| Alloying element | Carbon | Silicon | Manganese | Nickel | Chrome | Tungsten | Copper |
| Percentage of material | 0,61 0,69… | 1,50 2,00… | 0,70 1,00… | To 0.25 | To 0.30 | 0,80…1,20 | To 0.20 |
The composition of the steel, there are also sulfur and phosphorus, which are metallurgical impurities. Their number in the steel should not exceed 0.025% of each of the elements.
The closest European equivalent steel 65S2VA is considered high-carbon steel 65Si7. Its chemical composition includes not more than 0.7% silicon, traces of copper, tungsten is not provided.
The company Electrocentury steel offers to buy these spring steel at the best price from the manufacturer. The supplier guarantees the quality of the acquired circle of wire or rod.
Steel 65S2VA, 65Si7 can undergo various types of heat treatment, not prone to temper embrittlement and to the formation of placenow during plastic deformation. The weldability of the steel is unsatisfactory.
Main physico-mechanical properties:
