kwa kadhalika; Ina jumla ya kiwango cha alloy < 3%. Inagawanywa katika ngazi nne kulingana na nguvu ya 300, 350, 400 na 450MPa. Mawasiliano makubwa ni Q295, Q345, Q390 na Q420.
Q460。 "Q" ni kujitolea kwa "屈" neno Kichina Pinyin huruf kubwa, baadaye namba ni alama ya alama ya chini ya kujitolea hatua (σs) thamani, baadaye ishara ni kulingana na chuma uchafu vipengele (sulfuri, fosfori) maudhui kutoka juu hadi chini na
| Pamoja na mabadiliko ya kaboni, manganese vipengele na kugawanywa katika A, B, C, D, nk. A na B chuma kwa kawaida inaitwa 16Mn | |||
| Kemikali ya 16Mn chini alloy tube: | C: 0.12 ~ 0.20; Mn:1.20~1.60； Si:0.20~0.55； Nguvu ya kuvutia: 470 ~ 660 ng / mm za mraba; | Kujitolea nguvu: 275 ~ 345 ng / mm mraba; Kiwango cha kuongezeka: 21%. Thamani maalum kulingana na unene au kipenyo cha chuma, data hapo juu inahusiana na unene au kipenyo cha chuma ni: 16 ~ 100mm | 16Mn chini ya chuma bomba |
