Description

Steel SV-09ХГНМТА used: for the production of welding wire with a diameter of 3−5 mm, used for welding steels of 15Х2НМФА and 15Х3НМФА various modifications category КП45 strength at 350 °C in thicknesses up to 400 mm, including a narrow-gap butchering. Have a good adaptability. The weld metal made using the welding wire characterized by high resistance to embrittlement under the influence of neutron irradiation and thermal embrittlement in service. Provide Тк0 weld not higher than -15 °C.
