Nā Kūlana ASTM:

A20/A20M: Hōʻike no nā Koina Nui no nā Pāpaʻi Paʻi Moku
A435/A435: No ka ho'āʻo ʻana i ka Ultrasonic Straight-Beam o ka pā kila.
A577/A577M: No ka ʻike ʻana i ka ʻenekini kani ultrasonic o nā pā kila.
A578/A578M: ​​No ka hoʻokolokolo ʻana i ka Ultrasonic Straight-Beam o nā pā kila i ʻōwili ʻia no nā noi kūikawā.

Manufacturing Notes:

ʻO ka pā kila ma lalo o ka ASTM A537 Class 1, 2 a me 3 e pepehi ʻia i ke kila a hoʻokō i nā koi nui austenitic maikaʻi o ka kikoʻī A20/A20M.

Nā ʻano hana wela:

ʻO nā papa āpau ma lalo o ka ASTM A537 e mālama ʻia ka wela e like me kēia:
ʻO nā papa ASTM A537 Class 1 e hoʻomaʻamaʻa ʻia.
E kinai ia na papa Papa 2 a me Papa 3. ʻAʻole emi ka mahana wela no nā papa Papa 2 ma lalo o 1100°F [595°C] a ʻaʻole emi ma lalo o 1150°F [620°C] no nā papa Papa 3.
