Moscow, Metallurgiz- dat, 1958, pp 21-30 ABSTRACT: An investigation is made of the tendency of 15KhZGNTA, 25KbZGNTA, 3OKh2NZVA, and 30Kh3VA steels to overheat in the 900- B000C temperature interval, and the possibility of cerrecting this tendency is studied. It is found that overheat- ing may be corrected by normalization at 900-9500. The standard mechanical properties of the overheated and the normally treated metal are identical. The overheating effect is found in impact testing at -700, in notch tensile testing at 80 notch angle and in fatigue testing; overheating reduces ak from 9 to 3.4 kgn-i/cm?- 0 b from 106 to 68- 77 kg/rnm2. and a-- I by Card Wz .3-6 kg/inm2.

Thus coml)lote transformation of austenite into scrbite- Me pearlito Is assured by isothermal annealing of both steels at 750-780*C for I hr. The op- timal quenching temperature for EI955 steel Is 1025-1050'C and for 4Kh5V4FSML stee~105D- 1075*C. Compared with the conventJonal die steel 3Kh92V8 (HRC 46-5S,quenching temperature 1125-1150'C) tlic stools EID55 and 41WV4FSM always display a higher hardness (H RC 58-59) after haivIcning, o-ning to their moro balanced ratio of W (at.%) to C (at. %),WIC - 1. 25 (nee Cwd 1/3 UDC: 620.17:669.14.254 ACC NR.

The effect of tempering on the mechanical properties of all three stools was investigated as a function of the tempering temperature and it was found that, on tempering at 550*C all these steels have high strength proporUes but low plasUe properties.
