Ь Лр0.2 таУ be estimated by lowering Яр10 by 25 MPa

c + N means Normalizing; + QT or + QT1 or + QT2 means quenching (air or liquid) + tempering; AT means: solution annealing + water quenching

d Quenching in air.

e The requested alternative shall be indicated on the order e.g.: GX8CrNi12 + QT1 or 1.4107 + QT1.

f After solution annealing at high temperature, castings may be cooled down to between 1 050 °С and 1 010 °С prior to water quenching in order to improve corrosion resistance and prevent

cracks in complex shapes.

9 The low temperatures impact properties shall conform to Table 4 for ferritic and martensitic grades and may be agreed according to values of Table 5 for austenic and austenic-ferritic grades used at low temperatures.

h As cast conditions.

’ For centricast, 440 MPa to 640 MPa

J For centricast, 25 %.
