Ua hoʻouna ʻia nā paipu kila ʻano huinahā DIN 17100 St52.3 i Australia.
ʻO DIN 17100 ke kūlana maʻamau i hoʻopili ʻia i nā ʻāpana kila, nā kaola kila, nā koʻokoʻo uea, nā huahana pālahalahaʻaʻohe ona pilinaa me nā ʻāpana hakahaka i hoʻopaʻa ʻia, ʻehā a me nā ʻāpana ʻehā, nā forgings, a me nā huahana semi-hoʻopau ʻia i nā kila kūkulu maʻamau i hāʻawi ʻia i ke kūlana wela a i ʻole ke kūlana maʻamau ma hope o ka hana ʻana.
ʻO St52.3 kekahi o nā māka, a ʻo ka helu mea he 1.0570.
Ma mua o ka lawe ʻana, hoʻonohonoho ʻo Botop i nā limahana akamai e nānā pono i nā huahana e hōʻoia i ka hoʻokō pono ʻana o ka maikaʻi o ka huahana i nā koi o ka mea kūʻai.
ʻO ka mea mua, e nānā pono ʻia ke ʻano o ka ʻili, ka laulā, ke kiʻekiʻe, ka lōʻihi, ke kūlike, a me nā ana ʻē aʻe o ke ʻano o ka paipu kila e hōʻoia i ka mālama ʻana i nā kūlana a me nā koi o nā mea kūʻai aku.
ʻO ka mea aʻe, nānā ʻia nā waiwai kemika a me nā mechanical o ka paipu kila kila.
Aia i loko o EN 17100 St52.3 nā koi hoʻohui kemika penei:

Ua ana ʻia ke ʻano kemika o St52.3 e kahi spectrometer, a ua kūlike nā ʻike āpau o nā mea i nā koi o ka mea kūʻai aku i hoʻohālikelike ʻia me nā koi kūpono.
ʻO nā waiwai mechanical o EN 17100 St52.3 e komo pū me ka ikaika tensile a me ka ikaika yield, i ana ʻia e ka hoʻāʻo tensile.

Ma hope o ka hoʻopau ʻana i nā nānā āpau a me ka hōʻoia ʻana ua kūlike ka maikaʻi me nā koi maʻamau, hoʻopuka ʻia kahi Palapala Hōʻike Mea Hana (MTC). Ma hope iho, ua hoʻonohonoho ʻia no ka hoʻouna ʻana a me nā hana e pili ana.
Mai kona hoʻokumu ʻia ʻana i ka makahiki 2014, ua lilo ʻo Botop Steel i mea hoʻolako alakaʻi o nā paipu kila kalapona ma ka ʻākau o Kina, i ʻike ʻia no kāna lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hoʻonā piha.
No kēlā me kēia kauoha, pili mau ʻo Botop i ke ʻano o ka hilinaʻi kūpono a me nā kumukūʻai kūpono, e koho ana iā mākou e hāʻawi iā ʻoe i nā huahana paipu kila hilinaʻi.
