不鏽鋼製品的材料成本雖為碳鋼的五至十倍多，但如果我們用時間價值來看，不銹鋼使用壽命長久，生命週期成本低廉很多。

結果 (英文) 1:

Although the material costs for stainless steel products, carbon steel five to ten times as much, but if we look at the time value of stainless steel long life and low life-cycle costs a lot.

結果 (英文) 2:

Although the material cost of stainless steel products is more than five to ten times that of carbon steel, but if we use the time value, stainless steel long life, life cycle cost is much lower.

結果 (英文) 3:

Although the material cost of stainless steel products is more than five to ten times that of carbon steel, if we use the value of time, the service life of stainless steel is long and the life cycle cost is much lower.
