Zusammenfassung:	FIELD: rolled stock production. ^ SUBSTANCE: bent channel, mainly with thickness S = 7 - 8 mm from low-alloy steel strip blank with predetermined properties is made of manganese steel containing boron and vanadium. Channel has temporary strength sigmaB in range 600 - 610 MPa and relation of yield limit value sigmaT and sigmaB value sigmaT /sigmaB = 0.87 - 0.90. It provides radius values R of bent zones no more than 1.5S. ^ EFFECT: improved operational properties of bent channels of low-alloy steel blank of increased strength. ^ 1 dwg, 1 ex
