Zomwe zili mu Chrome Moly Plate

Mbale ya Chrome moly pansi pa ASTM A387 m'magawo angapo omwe ali ndi zinthu zosiyanasiyana monga momwe zilili pansipa, magawo ogwiritsidwa ntchito nthawi zambiri ndi Gr 11, 22, 5, 9 ndi 91.

Kupatula 21L, 22L ndi 91, giredi iliyonse imapezeka m'magulu awiri a mphamvu yokoka monga momwe tafotokozera m'matebulo a zofunikira pakukoka. Giredi 21L ndi 22L ili ndi Kalasi 1 yokha, ndipo Giredi 91 ili ndi Kalasi 2 yokha.

Miyezo Yotchulidwa ya ASTM A387 Alloy Steel Plate ASTM

A20/A20M: Zofunikira zonse pa mbale za mtsempha wopanikizika.
A370: Kuyesa kwa mawonekedwe a makina a chitsulo
A435/A435M: Kuwunika mbale zachitsulo pogwiritsa ntchito ultrasound.
A577/A577M: Kuwunika kwa chitsulo pogwiritsa ntchito ultrasound.
A578/A578M: Kuwunika kwa UT kwa mbale zachitsulo zopindidwa pogwiritsa ntchito njira zapadera.
A1017/A1017M: Mafotokozedwe a mbale zoyendetsera zitsulo zoponderezedwa zopangidwa ndi chitsulo cha alloy, chromium-molybdenum-tungsten.

Kufotokozera kwa AWS

A5.5/A5.5M: Ma electrode achitsulo chopanda aloyi ambiri ogwiritsira ntchito kulumikiza arc yachitsulo choteteza.
A5.23/A5.23M: Ma electrode achitsulo chopanda aloyi ambiri a ma fulxes ogwiritsira ntchito kulowetsa arc pansi pa nthaka.
A5.28/A5.28M: Yothandizira kuwotcherera arc yotetezedwa ndi mpweya.
A5.29/A5.29M: Yothandizira kuwotcherera arc yokhala ndi ma cored flux.

Kutentha kwa A387 Chrom Moly Alloy Steel Plate

Mbale yachitsulo ya Chrome moly alloy pansi pa ASTM A387 iyenera kukhala yachitsulo chophwanyika, chotenthetsera ndi kutentha pogwiritsa ntchito annealing, normarlizing ndi tempering. Kapena ngati wogula avomereza, kuziziritsa kwachangu kuchokera kutentha kwa austenitizing pogwiritsa ntchito mpweya wophulika kapena madzi ozimitsa, kutsatiridwa ndi tempering, kutentha kochepa kwa tempering kuyenera kukhala motere:

Giredi	Kutentha, °F [°C]
2, 12 ndi 11	1150 [620]
22, 22L, 21, 21L ndi 9	1250 [675]
5	1300 [705]

Mapepala achitsulo a Giredi 91 ayenera kutenthedwa ndi kutentha mwa kusinthasintha ndi kutenthetsa kapena kuziziritsa mofulumira mwa kuphulika kwa mpweya kapena kuzimitsa madzi, kutsatiridwa ndi kutenthetsa. Mapepala a Giredi 91 ayenera kutenthedwa pa 1900 mpaka 1975°F [1040 mpaka 1080°C] ndipo ayenera kutenthedwa pa 1350 mpaka 1470°F [730 mpaka 800°C]

Ma mbale a Giredi 5, 9, 21, 21L, 22, 22L, ndi 91 omwe adalamulidwa popanda kutentha ndi tebulo lomwe lili pamwambapa, ayenera kumalizidwa ali ndi vuto lochepa kapena lochepetsedwa.
