STAINLESS STEEL 420 COIL WELDING:

420 coils

Tsis nquag welded vim huab cua hardening yam ntxwv.
Vuam tej zaum yuav ua tau tom qab preheating rau 300-400 F
Post weld tempering ntawm qhov kub thiab txias rau 2 teev
Pom zoo kom coj qhov kub thiab txias maj mam mus txog 1400, tom qab ntawd mus rau 2000-2200 F
Rauv txias maj mam kom tsis txhob tawg, tom qab qhov cub ua haujlwm
Reheating yog tsim nyog kom ua haujlwm kub siab tshaj 1600 F.

STAINLESS STEEL 420 COIL txias ua haujlwm:

420 stainless steels

Muaj peev xwm tiv taus tsuas yog me me ua haujlwm txias.
Radical kev ua haujlwm yuav ua rau tawg.
STAINLESS STEEL 420 COIL ANEALING:
Anneal ntawm qhov kub ntawm 1550-1650 F (843-900 C)
Cia lub cub tawg qeeb qeeb.

STAINLESS STEEL 420 COIL TEMPERING:

Kub ntawm qhov kub ntawm 300-400 F
Cua txias rau siab tshaj plaws hardness thiab corrosion kuj.

STAINLESS STEEL 420 COIL HARDENING:

Soak ntawm 1850-1950 F kom tua hauv cov roj kub.

Qhov no yog cov nqi zoo tshaj plaws ntawm cov hlau. Yog li 420 Stainless Steel coil Nqe yog qis dua piv rau lwm qib ntawm stainless hlau thiab tag nrho cov khoom siv hlau feem ntau. Muaj cov khoom sib txawv ntawm cov khoom siv nrog cov pa roj carbon tsawg thiab cov ntsiab lus siab carbon. Qhov qis carbon version, 420 coils yog qhov zoo heev rau kev siv vuam vim tias lawv muaj cov nag lossis daus tsawg thiab tsis tshua muaj zog hauv zos.
