ASTM A194

O le ASTM A194 fa'amatalaga e aofia ai le kaponi, u'amea ma nati u'amea uamea fa'amoemoe mo le fa'aoga i le maualuga o le mamafa ma/po'o le maualuga o le vevela. Se'i vagana ua fa'amaonia mai, e tatau ona fa'aoga le American National Standard Heavy Hex Series (ANSI B 18.2.2). O nati e o'o atu ma aofia ai le 1 inisi le lapopo'a e tatau ona fetaui ma le UNC Fa'asologa Vasega 2B. O nati e sili atu i le 1 inisi le lapopo'a fa'atatau ole UNC Fa'asologa Vasega 2B fetaui po'o le 8 UN Fa'asologa Vasega 2B fetaui. Ole malosi maualuga ole ASTM A194 grade 2H nati e masani lava ile maketi ma e masani ona sui mo ASTM A563 grade DH nati ona ole utiuti ole maua ole DH nati ile tele ma fa'auma.

FAAMATALAGA: 1. O fa'ailoga o lo'o fa'aalia mo vasega uma o nati A194 e mo nati fa'amea malulu ma fa'avela. A fa'amuina nati mai fa'atau pa, e tatau ona fa'ailogaina le nati i le mata'itusi 'B'. O mataitusi H ma le M o loʻo faʻaalia ai nati ua faʻafefeteina. 2. O mea totino o lo'o fa'aalia o nati hex mamafa ma le 8-pitch filo lapopoa. 3. O numera maaa o Brinell Hardness. 4. O nati o lo'o fa'aogaina i le carbide-solusi e mana'omia se mata'itusi faaopoopo A – 8A po'o le 8MA. 5. O nati uma e tatau ona iai le fa'ailoga e iloagofie ai le gaosi oloa. E tatau ona fa'ailogaina nati ile mata e tasi e fa'ailoa ai le vasega ma le fa'agasologa ole gaosiga. E le fa'atagaina le fa'ailogaina o fa'ama'i mafolafola po'o mea fa'amau se'i vagana ua malilie i ai le kamupani gaosi ma le fa'atau. O nati e ufiufi i le zinc ei ai le fetū (*) e makaina i tua o le faailoga o le vasega. O nati e ufiufi i le cadmium e tatau ona iai se fa'ailoga fa'aopoopo (+) fa'ailoga pe a uma le fa'ailoga togi. 6. O lo'o iai isi togi e le masani ai, ae le o lisiina iinei.
