I'm forming steel in hot condition about 900 Deg C and quenching using water , but actually the yield and tensile strength is lost after that , i think i can re-gain the orginal properties using heat treatment but i don't know how , ,,, any idea?

i propose you at first normalize it that is heat it to normalising temperature then cool it at air . at this state steel have original structure ( as cast) . then you can heat treatment for special perpose. hope be usefull for you.

Heat treating changes the properties of a material. Normally it makes the steel stronger, but sometimes more brittle. Be sure to check all charts and lists of what you want to do to which material before you do it. You may end up with the wrong results. Try looking in metallurgical handbooks for these charts.

Oh your in deep lol.Instant quenching is hardening it . You have to either slow the cooling or. Reheat and draw it back . Uhm dont know the material your using. But if you reheat it 900 then let it air cool and reheat to about 400 and draw it back down again slowly you may gain some properties back . Have you tried quenching in oil?

absolutely correct. the basic process inputs are:
austenizing
forming
quenching
annealing
what material are you using?
what is the output required?
