EN 10216-1 P235 ni nyenzo ya kawaida ya bomba la chuma. Kulingana na kiwango, imegawanywa katika darasa mbili: TR1 na TR2. TR1 haihitaji matibabu ya joto, wakati TR2 inahitaji matibabu ya kawaida. TR2 ni takribani sawa na TR2 kwa suala la utungaji wa kemikali, lakini inahitaji vipengele vya ziada; TR1 na TR2 ni takribani sawa katika suala la sifa za mitambo. Tofauti ni kwamba TR1 haihitaji majaribio ya athari, ilhali TR2 inahitaji majaribio ya athari ya 0°C. Mahitaji ya ukaguzi wa mabomba ya kumaliza pia ni tofauti kwa TR1 na TR2. TR1 inahitaji ukaguzi wa kawaida pekee, wakati TR2 inahitaji ukaguzi maalum (jaribio la athari ya ziada).
Ikiwa hakuna mahitaji maalum, EN10216 P235 TR1 ndiyo inayotumiwa zaidi, sawa na daraja la chuma la Kichina GB/T8163 20# au GB/t8162 Q235C, na inaweza kubadilishwa kwa kila mmoja.

a.Mbali na gredi za Q345A na Q345B, chuma kinapaswa kuwa na angalau moja ya vipengele vya nafaka vilivyosafishwa Al, Nb, V, na Ti. Kulingana na mahitaji, muuzaji anaweza kuongeza moja au zaidi vipengele vya nafaka iliyosafishwa. Thamani ya juu itakuwa kama ilivyoainishwa kwenye jedwali. Inapojumuishwa, Nb + V + Ti sio zaidi ya 0.22%b. Kwa alama za Q345, Q390, Q420 na Q46O, Mo + Cr sio zaidi ya 0.30%c. Wakati Cr na Ni za kila daraja zinatumiwa kama vipengele vya mabaki, maudhui ya Cr na Ni haipaswi kuwa zaidi ya 0.30%; inapohitajika kuongeza, yaliyomo yanapaswa kukidhi mahitaji kwenye jedwali au kuamuliwa na muuzaji na mnunuzi kupitia mashauriano.d. Ikiwa msambazaji anaweza kuhakikisha kuwa maudhui ya nitrojeni yanakidhi mahitaji katika jedwali, uchanganuzi wa maudhui ya nitrojeni hauwezi kufanywa. Ikiwa Al, Nb, V, Ti na vipengele vingine vya alloy na fixation ya nitrojeni huongezwa kwa chuma, maudhui ya nitrojeni sio mdogo. Maudhui ya urekebishaji wa nitrojeni yanapaswa kubainishwa katika cheti cha ubora.e. Unapotumia alumini kamili, jumla ya maudhui ya alumini Alt ≥ 0020%. |

Katika mtihani wa mvutano, sampuli za transverse au longitudinal zinaweza kuchukuliwa. Katika kesi ya kutokubaliana, sampuli ya longitudinal hutumiwa kama msingi wa usuluhishi.c. Chuma kilicho na boroni kinaweza kurekebishwa kabla ya kuzima, na hali ya joto ya kawaida haipaswi kuwa kubwa kuliko joto lake la kuzima.d. Uwasilishaji kulingana na seti ya data iliyoainishwa na mwombaji. Wakati mwombaji hajataja, uwasilishaji unaweza kufanywa kulingana na data yoyote. e. Uzimaji wa kwanza wa chuma cha titan na Ming Meng unaweza kubadilishwa na kurekebisha. f. Uzimaji wa isothermal kwa 280 C ~320 C. g. Katika jaribio la mvutano, ikiwa Rel haiwezi kupimwa, Rp0.2 inaweza kupimwa badala ya Rel. |
