請問有經驗的車友. 1. dedacciai sat 14.5 管材, 2. 雷諾853 管材. 這兩種管材之間的優缺點為何? 何者管材較優呢? 謝謝
| Tubing | Material | Ultimate Strength | Minimum Elongation | Description |
| Reynolds 853 | Proprietary Air Hardening Heat Treated | 180-210 KSI | 10% min | Reynolds853 is made from a seamless steel alloy originally developed for the side impact beams on high performance cars. The term 駮ir-hardening?refers to a special category of steels that when welded and allowed to cool in air, actually get harder in the weld area. Because this is normally the critical zone for fatigue life, 853 frames will out-perform conventional steel alloys due to this innovation. |
| Dedacciai SAT 14.5 | 18MCDV6 Micro alloy | >203KSI | 13% min | A heat-treated Micro alloy. Both extremely light, and super strong, this tube set possess excellent fatigue characteristics. Available in standard and oversize tubes. |
這邊找到的,不過看不懂,有前輩可以解釋一下嗎, 2008,04,17 AM12:33

就您提供的表來看兩種管材實在差異極小
1.極限強度差3KSI,基本上算同級!
2.伸長率DEDA可較853多3%,應可勉強解釋為較Q(韌性較佳)吧!
3.其他敘述是指製作及銲接應注意事項,這些項目853敘述較詳細,原廠建議該管材係經熱處理製成之無縫合金鋼管,焊接後應以空冷(亦即禁止水淬),以避免焊接處硬.脆化,相對DEDA標示其合金成分,但是DEDA基本上亦屬經熱處理製成之無縫合金鋼管(就其性能及現今技術層面),其處理過程應予853大同小異,但這也點出一項重點,不管任合管材焊接及後處理,才是重點!!但消費者卻看不到,只能道聽塗說,靠口耳相傳,誰的管材比較棒,事實上是沒有任何意義的口水吧!
有問題不妨大家再討論吧!
