ASTM A194

Hoʻopili ka ASTM A194 kikoʻī i ke kalapona, ka hao a me nā nati kila kila i manaʻo ʻia no ka hoʻohana ʻana i ka lawelawe kiʻekiʻe a / a i ʻole ka wela wela. Inā ʻaʻole i kuhikuhi ʻia, e hoʻohana ʻia ka American National Standard Heavy Hex Series (ANSI B 18.2.2). Pono nā hua a hiki i ka 1 ʻīniha ka nui o ka UNC Series Class 2B kūpono. ʻO nā hua i ʻoi aku ma mua o 1 ʻīniha ka nui o ka inoa UNC Series Class 2B kūpono a i ʻole 8 UN Series Class 2B kūpono. ʻO ka ikaika kiʻekiʻe ka ASTM A194 grade 2H nati he mea maʻamau i ka mākeke a ua hoʻololi pinepine ʻia no ka ASTM A563 grade DH nati ma muli o ka liʻiliʻi o ka loaʻa ʻana o nā nati DH i kekahi mau anawaena a me ka pau ʻana.

MAKEMAKE: 1. ʻO nā hōʻailona i hōʻike ʻia no nā papa āpau o nā nati A194 no nā nati i hana ʻia i ke anu a me nā nati wela. Ke hana ʻia nā hua ʻai mai ka pahu pahu, pono e hoʻopaʻa ʻia ka nati me ka huapalapala 'B'. Hōʻike nā huapalapala H a me M i nā nati i mālama ʻia me ka wela. 2. ʻO nā waiwai i hōʻike ʻia, ʻo ia nā ʻano o nā nati hex kaumaha a me 8-pitch thread. 3. ʻO nā helu paʻakikī ʻo Brinell Hardness. 4.
