ʻO ASTM-SA516Gr60Z35 ka ʻike hemahema o ka pā kila:
1. SA516Gr60 kūlana hoʻokō: American ASTM, ASME kūlana
2. SA516Gr60 no ka ha'aha'a wela kaomi ipu me kalapona kila pā
3. Huina kemika o SA516Gr60
C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45.
4. Mechanical waiwai o SA516Gr60
SA516Gr60 ikaika tensile o 70 tausani paona / huinaha iniha, ka mea nui mea maʻiʻo C Mn Si ps mana hoʻoholo i kāna hana.ʻOi aku ka liʻiliʻi o nā mea ʻē aʻe.ʻO Asme Kūlana Kūlana no nā papa kila kalapona no nā kīʻaha haʻahaʻa haʻahaʻa.
5. Ke kūlana hoʻouna o SA516Gr60
Hāʻawi pinepine ʻia ka pā kila SA516Gr60 ma ka mokuʻāina ʻōwili, hiki ke hoʻomaʻamaʻa ʻia ka pā kila a i ʻole ka hoʻoluhi pilikia, a i ʻole ka hoʻomaʻamaʻa ʻana me ke kauoha hoʻomaha kaumaha.
SA516Gr60 mānoanoa> 40mm pā kila e pono e normalized.
Inā ʻaʻole i ʻōlelo ʻia e ka mea koi, pono e hoʻoponopono ʻia ka mānoanoa o ka pā kila ≤1.5in, (40mm), inā loaʻa nā koi toughness.
6. Hoʻohana ʻia ʻo SA516Gr60 no ka hana ʻana i ka pahu kuʻi wili hoʻokahi-layer, multi-layer hot sleeve coil welding container, multi-layer dressing container a me nā ʻano pahu ʻelua a ʻekolu a me nā kīʻaha haʻahaʻa haʻahaʻa.Hoʻohana nui ʻia i ka ʻaila, ka ʻoihana kemika, ka mana mana, ka paila a me nā ʻoihana ʻē aʻe, i hoʻohana ʻia i ka hana ʻana i nā reactors, nā mea hoʻololi wela, nā mea hoʻokaʻawale, nā pahu spherical, ka aila a me nā pahu kinoea, nā pahu pahu wai, ka pahu boiler, liquefied petroleum steam cylinders, hydropower station nā paipu wai kiʻekiʻe, turbine volute a me nā mea hana a me nā mea ʻē aʻe.ʻ
7. Ke hooluolu lohi ka austenite (e like me ka hooluolu o ka umu ahi, e like me ka hoike ana ma ka Fig. 2 V1), ua kokoke na hua hoololi i ka equilibrium structure, oia hoi ka pearlite a me ka ferrite.Me ka piʻi ʻana o ka hoʻoluʻu ʻana, ʻo ia hoʻi, i ka wā V3> V2> V1, piʻi mālie ka undercooling o austenite, a ʻoi aku ka liʻiliʻi o ka ferrite precipitated, ʻoiai e piʻi mālie ka nui o ka pearlite, a ʻoi aku ka maikaʻi o ka hale.I kēia manawa, hoʻokaʻawale ʻia ka hapa liʻiliʻi o ka ferrite precipitated ma ka palena ʻai.
8. No laila, ʻo ka hana o v1 he ferrite+pearlite;ʻO ka hana o v2 he ferrite+sorbite;ʻO ka microstructure o v3 he ferrite+troostite.
9. I ka v4 ka helu hooluolu, ua hookaheia ka nui o ka ferrite a me ka troostite (i kekahi manawa ke ike ia ka bainite), a ua hoololiia ka austenite i martensite a me troostite;Ke ʻoi aku ka nui o ka hoʻoluʻu v5 i ka nui o ka hoʻoilo koʻikoʻi, hoʻololi ʻia ke kila i martensite.
10. Ua like ka hoololi ana o ke kila hypereutectoid me ke kila hypoeutectoid, me ka like ole o ka ferrite precipitates mua ma ka hope a me ka cementite precipitates mua ma mua.
Ka manawa hoʻouna: Dec-14-2022
