17-4PH 630 Irin Alagbara Pẹpẹ
Apejuwe kukuru:
Saky Steel's 17-4PH / 630/1.4542 jẹ ọkan ninu olokiki julọ ati awọn irin alagbara alloy chromium-nickel alloy ti o wọpọ julọ ti a lo pẹlu afikun Ejò, ojoriro lile pẹlu ilana martensitic. O jẹ ijuwe nipasẹ resistance ipata giga lakoko mimu awọn ohun-ini agbara giga, pẹlu lile. Irin le ṣiṣẹ ni iwọn otutu lati -29 ℃ si 343 ℃, lakoko ti o ni idaduro awọn aye to dara. Ni afikun, awọn ohun elo ti o wa ni ipele yii jẹ ijuwe nipasẹ ductility ti o dara ati pe resistance ipata wọn jẹ afiwera si 1.4301 / X5CrNi18-10.
17-4PH, ti a tun mọ ni UNS S17400, jẹ irin alagbara ojoriro-lile. O jẹ ohun elo ti o wapọ ati lilo pupọ ni ọpọlọpọ awọn ile-iṣẹ, gẹgẹbi afẹfẹ, iparun, petrochemical, ati ṣiṣe ounjẹ.
17-4PH ni agbara ti o ga, ipata ipata ti o dara, ati lile ti o dara ni akawe si awọn irin alagbara miiran. O jẹ adalu 17% chromium, 4% nickel, 4% Ejò, ati iye kekere ti molybdenum ati niobium. Apapo awọn eroja wọnyi fun irin ni awọn ohun-ini alailẹgbẹ rẹ.
Iwoye, 17-4PH jẹ ohun elo ti o pọju ati ti o wulo ti o funni ni iwontunwonsi ti o dara fun awọn ohun elo ti o pọju.
