Name	The value
Weldability	Limited weldability. The welding methods of SMAW, ADS submerged arc and gas protection electroslag welding. Recommended heating and subsequent heat treatment. The CCC without restriction.
Склонность к отпускной хрупкости	Tend not.
The temperature of forging	Start - 1280 °C, the end - 750 °C. the Workpiece cross-section up to 800 mm are cooled in air.
Flock-sensitive sensitivity	not sensitive.
Machinability	In hot rolled state at NV 144-153 and blower SB=510 MPa Kn TV.SPL.=1,3.
Surfacing	Surfacing of sealing surfaces of valves in accordance with OST 26-07-2028-81 is made by manual arc welding electrodes type e-20X13 with plaster SSSI-13НЖ, NII-48, NII-48Ж-1 or SV wire-12H13 or SV-20X13. Surface preparation for overlay welding is performed by machining. Surfacing is performed with preliminary and accompanying heating to 400-450 °C is not less than 3 layers with thickness not less than 4 mm, excluding allowance for machining. Heat treatment after welding is produced by tempering at 550-600 °C (delay of 2-5 h) hardness HB=301-350, at 600-650 °C (delay of 2-5 h) hardness HB=240 to 300, at 400-450 °C (delay of 2-5 h) hardness HB=351-400. The temperature of the furnace when loading the details for the home should be no more than 300 °C.
