ʻO ka inoa wili kila maʻamau Iapana (JIS) -SPCC

ʻO SPCC ka mea maʻamau i ke kila Iapana (JIS) "maʻamau mepepa kila kalapona ʻōwili anuanua me ke kila kila" inoa, nui nā ʻāina a i ʻole nā ​​​​ʻoihana i hoʻohana pololei ʻia e hōʻike i kā lākou hana ponoʻī o ke kila like (e like me Baosteel Q / BQB402 maʻamau he SPCC).
I ka Japanese JIS maʻamau, anu ka pepa kalapona ʻōwili ʻia he SPCC, SPCD, SPCE a me nā hōʻailona ʻē aʻe, i waena o nā mea hope ʻelua e hōʻike ana i ka hoʻopaʻa ʻana a me ka hoʻoheheʻe hohonu ʻana me ka pepa kalapona i ʻōwili ʻia, ua like ia me 08AL kiʻekiʻe kiʻekiʻe carbon structural steel ma Kina 13237 maʻamau a me 08AL hao hohonu holoi ma 5213 maʻamau.
ʻO ka SPCC ka mea maʻamau e hoʻohana i ka pepa kalapona i ʻōwili ʻia, e like me Q195-Q215A ma Kina, mai hana i ka hoʻāʻo stamping, pono e hōʻoia i ka hoʻāʻo tensile, ma hope o ka helu brand T no SPCC-T a i ʻole SPCCT.
I kekahi mau hihia, e kuhikuhi ka helu SPCC i kona code control quality and surface processing code. I waena o lākou, ʻo ke code hoʻoponopono maikaʻi ʻo ia: A —— state annealing;S —— hoʻoponopono maikaʻi maʻamau;8 —— 1 / 8 paakiki;4 —— 1 / 4 paakiki;2 —— 1 / 2 paakiki;1 —— paakiki.
Helu hoʻoponopono ʻili: D —— ʻōwili maikaʻi ʻia;B —— ʻōlinolino maikaʻi. No ka laʻana, SPCC-SD ʻo ia ka hoʻololi ʻana i ka maikaʻi maʻamau, ka pepa kalapona i ʻōwili ʻia ma ke ʻano anuanu, ʻo SPCCT-SB ʻo ia ka hoʻololi ʻana i ka maikaʻi maʻamau, ka hana ʻālohilohi, ka pepa kalapona i ʻōwili ʻia e pono ai e hōʻoia i ka pepa hana mechanical, a pela aku.
