Weldability |
Without restrictions. Resistant to hot cracks during welding and similar steel 10Т2С1, currently used for the manufacture of rolled pressure vessels. Weld steel 08Г2СФБ vypolneniya manual arc welding electrodes SSSI 13/55, and automatic welding with wire SV-08G2S under the flux an-43 that provide a durable base metal joints, high plastic properties. |
Microstructure |
Fine-grained ferritic-pearlitic structure with a grain size of 11-12 is obtained by controlled rolling. |
