420J1 420J2 strip steel ah
Sharraxaadda Gaaban:
420J1 iyo 420J2 Strips bir ah oo bir ah ayaa ah laba nooc oo caadi ah oo ah alaab bir ah oo aan caadi ahayn oo ka tirsan taxanaha birta ee loo yaqaan 'Wetsitic'. Waxay ku kala duwan yihiin waxoogaa kala duwan oo ka kooban isku dhafka kiimikada iyo astaamaha. Halkan waxaa ah dulmar guud oo kooban oo midkasta:
1. 420J1 STIP STIPE STEES: 420J1 waa bir yar yar oo bir bir yar leh oo leh xoog sare iyo xoog. Halabuurka kiimikada ayaa sida caadiga ah ka kooban 0.16-0.25% kaarboon, qiyaastii 1% chromium, iyo qaddar yar oo molybdenum. 420J1 waxay bixisaa iska caabbinta hufnaanta wanaagsan, goynta waxqabadka, iyo sifooyinka shiidi. Waxaa badanaa loo isticmaalaa samaynta mindiyo, aalado qalliin, qaybo farsamoyaqaan, iyo qaar ka mid ah codsiyada u adkaysta.
2. 420J2 Strip Strees Streel ah Halabuurka kiimikada ayaa badanaa ka kooban 0.26-0.35% kaarboon iyo qiyaastii 1% chromium. 420J2 waxay leedahay kaarboon kaarboon ah marka loo eego 420J1, taasoo dhalisay in la kordhiyo adkaanta iyo goosashada waxqabadka. Waxaa si isdaba-ka ah loogu talagalay soosaarka mindiyaha, caloosha, aaladda qalliinka, ilaha, iyo qaybo farsamo yaqaan ah.
