Brinell hardness for 45KH14N14V2M ( 45Х14Н14В2М ) (annealing) , Bar GOST 5949-75

HB 10 -1 = 197 - 285 MPa

Weldability :

without limitations- welding is done without heating and subsequent heat treeting

limited weldability- welding is possible under heating up to 100-120 grade and subsequent heat treeting

hard weldability- obtaining the quality welding needs the additional operations:heating up to 200-300 grade; the heat treeting ia annealing
