These metals come in a wide assortment of alloys - base metals imbued with other metallic elements that produce a sum greater than its parts. There are dozens of titanium alloys and hundreds more steel alloys, so it can oftentimes be challenging to decide where to begin when considering these two metals. This article, through an examination of the physical, mechanical, and working properties of steel and titanium, can help designers choose which material is right for their job. Each metal will be briefly explored, and then a comparison of their differences will follow to show when to specify one over the other.
Explanation:
in the ph. above
