SA387 GR.12 CL2 Paʻi Paʻi Paʻa Paʻa

A387 Papa 12 CL 1, A387 Papa 12 CL 2 aia ma lalo o ke kila kiko'ī ma'amau ASTM A387/A387M no ka ipu hao pa'ipa'i, hao hui 'ia me Chromium-Molybdenum. 'O ka pā kila like SA387 Grade 12 CL 1 a me SA387 Grade 12 CL 2 aia ma lalo o ʻAmelika kila stamdard SA 387 / SA 387M. ʻO kēia mau pā kila kila i manaʻo nui ʻia no nā boilers welded a me nā moku kaomi & tank. Rolling maximum mānoanoa o nā papa ua kaupalena wale ʻia e ka hiki o ka haku mele e hoʻokō i nā koi waiwai mechanical.
No ka ipu hao paʻi SA387 Grade 12 CL 1, aia ka ikaika tensile i loko o 380 a 550, ʻo 230 Mpa ka liʻiliʻi o ka ikaika. ʻoi aku ka helu ma luna o 275 Mpa. Ma waho aʻe o nā mea nui ʻelima, ʻo Cr-Mo kekahi i loko o ka haku mele no kēia mau mea hao.
