4J36 waxay isticmaashaa alxanka oxyacetylene, alxanka korantada, alxanka iyo hababka kale ee alxanka. Maaddaama isku-dhafka balaadhinta iyo ka kooban kiimikada ee daawaha ay la xiriirto waa in laga fogaadaa sababtoo ah alxanka ayaa keenaya isbeddel ku yimaada halabuurka daawaha, waxaa la doorbidaa in la isticmaalo biraha alxanka alxanka Argon arc oo doorbidaya ka kooban 0.5% ilaa 1.5% titanium, si yaree porosity alxanka iyo dildilaaca.

Habka daaweynta kulaylka
Annealing si loo yareeyo walbahaarka	Kuleylka ilaa 530 ~ 550ºC oo qabo 1 ~ 2 saacadood. Qabow
nuugista	Si loo baabi'iyo qallafsanaanta, kaas oo lagu soo saaro qabow-duuban, habka sawirka qabow. Annealing waxay u baahan tahay kuleyl ilaa 830 ~ 880ºC meel faaruq ah, qabo 30 daqiiqo.
Habka xasilinta	Warbaahinta ilaalinta oo kuleyl ilaa 830ºC, qabo 20min. ~ 1 saac Cadaadiska ka dhashay deminta, kuleyl ilaa 315ºC, qabo 1 ~ 4h.
Ka taxadaritaan	Laguma adkeyn karo daawaynta kulaylka Daawaynta dusha sare waxay noqon kartaa ciid-qarxinta, dhalaalid ama qajaar. Alloy waxaa loo isticmaali karaa 25% hydrochloric acid xalinta 70ºC si loo nadiifiyo oogada oksaydheysan
