Select suitable alloy blank, its chemical composition and mass percent are: Cr:12.15%, Ni:2.27%, C:0.07%, Mo:0.55%, Cu:0.88%, Al:3.48%, W:0.34%, Si:0.272%, Mn:3.86%, Nb:0.93%, Ti:1.14%, Se:0.115%, all the other are Fe and inevitable impurity;
Alloy blank is placed in stove to be heated to 890 DEG C and to forge, the time is 21min, then temperature is reduced to 640 DEG C and forges, and the time is 16min, and then by alloy blank water-cooled to 300 DEG C, then air cooling is to room temperature, and removes iron scale;
Alloy blank is dried under nitrogen protection, and carries out phosphorating treatment;
Alloy blank after process is heated to 940 DEG C, and insulation 68min, is then reduced to 690 DEG C by temperature, insulation 52min, then adopt the alternately cooling of water-cooled-air cooling: first with the speed water-cooled to 530 DEG C of 6 DEG C/s, then air cooling to 380 DEG C, then with the speed water-cooled of 2 DEG C/s to room temperature;
Alloy blank after process is carried out drawing, adopts rotating mould wire drawing, first alloy blank is pulled into thicker wire, then thicker wire is heated to 470 DEG C, insulation 35min, is then cooled to 120 DEG C through oil cooling, adopt ultrasonic drawing that alloy blank is pulled into finer wire again, ultrasonic frequency is 20kHz;
Aluminized on finer wire surface after drawing, thickness of coating is 40nm, last coiling warehouse-in.
