Steel SV-09ХГНМТАА
Designation
Description
Steel SV-09ХГНМТАА 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.
Standards
Chemical composition
Fe is the basis.
According to TU 14-1-3675-2001 the chemical composition is presented for steel grade Sv-09HGNMTAA-VI. Deviations in the mass fraction are permissible: manganese -0,050%, chromium and nickel -0.10% each, nitrogen + 0.0050%, sulfur and phosphorus + 0.0020% each, other elements - within the requirements of GOST 2246 for alloyed wire become. Individual deviations in the mass fraction in the chemical composition of the steel are allowed to be agreed with the consumer enterprise.
