1.1 Hoʻopili ʻia kēia ʻōlelo kikoʻī i ka paila kila ferritic a me austenitic, superheater, a me nā paipu hoʻololi wela, i koho ʻia ʻo Grades T91, TP304, etc. Ua helu ʻia kēia mau kila ma ka Papa 1 a me 2.
1.2 He ʻokoʻa ko nā papa i loaʻa ka leka, H, ma ko lākou koho ʻana, ʻokoʻa nā koi o nā māka like ʻole me ka leka, H. ʻO kēia mau koi ʻokoʻa e hāʻawi i ka ikaika creep-rupture kiʻekiʻe ma mua o ka mea maʻamau i hiki ke loaʻa i nā māka like me ka ʻole o kēia mau koi ʻokoʻa.
1.3 ʻO ka nui a me ka mānoanoa o nā paipu i hoʻolako pinepine ʻia i kēia kikoʻī, he 1/8 iniha [3.2 mm] ke anawaena o loko a hiki i 5 iniha [127 mm] ma waho anawaena a me 0.015 a i 0.500 in.
