Mundo M3

※ ​旅行車款 皆無法選擇塗裝 / Touring bike series can't choose graphics.


M3 是以S32205 雙相不鏽鋼為基礎開發的無縫管材,瑞典在1930 年代開發出雙相不鏽鋼,它是由奧氏鐵(Austenite) 與鐵素體(Ferrite) 兩種不同結晶共同組成,這個材料被大量運用於高腐蝕性( 例如海水、酸性液體) 與高壓 (例如壓力容器) 的環境下。

M3 is made based on duplex stainless steel. The material was developed in Sweden in the  1930s. It has a microstructure consisting of both austenite and ferrite phases. The material is widely applied in highly corrosive (e.g. marine and acidic) and high pressure (e.g. pressure tanks) environment.


M3管材原用於海洋工程,保養非常容易。它的張力強度可達1100 MPa,因此可製成剛性非常好的車架,卻也不失鋼管的彈性。對於長途旅行而言,足夠的車架剛性方能讓高負重的旅行車在下坡時不會有扭曲甩尾的狀況,而產生危險。

M3 tube set was originally designed for marine environment, therefore, it is basically rust-free and easy to be taken care of.  The tensile strength can reach 1100MPa, so, a frame built with M3 is eligible to be a stiff and, yet, comfortable product.
