ʻO ke kila kalapona he mea hao-kāpona hao me kahi kalapona maʻiʻo o 0.0218% a 2.11%.Kapa ʻia hoʻi ke kila kalapona.ʻO ka maʻamau ka loaʻa ʻana o kahi liʻiliʻi o ke silika, manganese, sulfur, phosphorus.ʻO ka mea maʻamau, ʻoi aku ka kiʻekiʻe o ke kalapona i loko o ke kila kalapona, ʻoi aku ka paʻakikī a ʻoi aku ka kiʻekiʻe o ka ikaika, akā ʻoi aku ka haʻahaʻa o ka plasticity.

Hoʻokaʻawale:

(1) Wahi a ke kumu, hiki ke hoʻokaʻawale ʻia ke kila kalapona i ʻekolu mau ʻāpana: ke kila kila, ke kila kila a me ka ʻoki ʻoki manuahi, a ua hoʻokaʻawale hou ʻia ke kila kila i loko o ka ʻenekinia hana kila a me ka mīkini hana hana kila;

(2) E like me keʻano o ka hoʻoheheʻeʻana, hiki ke hoʻokaʻawaleʻia i ke kila kapuahi hāmama a me ke kila hoʻololi;

(3) Wahi a ke ʻano deoxidation, hiki ke hoʻokaʻawale ʻia i ke kila paila (F), ke kila pepehi ʻia (Z), ke kila semi-kiled (b) a me ke kila make kūikawā (TZ);

(4) Wahi a ke kalapona, hiki ke hoʻokaʻawale ʻia ke kila kalapona i ke kila kalapona haʻahaʻa (WC ≤ 0.25%), ke kila kalapona waena (WC0.25% -0.6%) a me ke kila kalapona kiʻekiʻe (WC> 0.6%);

(5) E like me ka maikaʻi o ke kila, hiki ke hoʻokaʻawale i ke kila kalapona i ke kila kalapona maʻamau (ʻoi aku ka phosphorus a me ka sulfur content), ke kila kalapona kiʻekiʻe (haʻahaʻa phosphorus a me ka sulfur content) a me ke kila kiʻekiʻe kiʻekiʻe (low phosphorus a me ka sulfur. maʻiʻo)) a me ke kila kila kiʻekiʻe.

Nā ʻano a me nā noi:

Nā mea hoʻohana kila kila: nā hale ʻenekinia maʻamau a me nā ʻāpana mīkini maʻamau.Eia kekahi laʻana, hiki ke hoʻohanaʻia ka Q235 no ka hanaʻana i nā bolts, nā nati, nā pine, nā makau a me nā'āpana mechanical liʻiliʻi, a me ka rebar, ka'āpana kila, nā pahu kila, a me nā mea'ē aʻe i nā hale kūkulu.

Ka hoʻohana ʻana i ke kila hoʻolālā kalapona kiʻekiʻe: Hoʻohana maʻamau ke kila non-alloy no ka hana ʻana i nā ʻāpana mīkini koʻikoʻi ma hope o ka mālama wela.Laʻana 45, 65Mn, 08F

Hoʻohana ʻia ke kila kila: Hoʻohana nui ia e hana i nā ʻāpana mechanical koʻikoʻi me nā ʻano paʻakikī a me nā koi hana mechanical kiʻekiʻe, akā paʻakikī ke hana ʻana ma ka forging a me nā ʻano hana ʻē aʻe i ke kaʻina hana, e like me nā pahu pahu pahu kaʻa, nā locomotive couplers a me nā hui pū E kali.
