Here is the article about knife blade of Window tint knives, let us beginning:
Knife blade for film cutting was usually made of carbon steel or stainless steel.
But do you know the difference between these two materials?
There are also many other types of stainless steels, but these are different in composition and structure and are rarely used in edge applications, since the edge properties are inferior to those of martensitic stainless steel grades.
Difference between carbon steel and stainless steel
There are two main differences between carbon knife steel and stainless knife steel. The first is that stainless steels have much higher corrosion resistance, due to the protective chromium oxide layer that covers the steel surface after heat treatment. The second difference relates to the alloying elements that form carbides. Stainless steels contain at least 10.5% by weight of chromium. The carbide particles provide the steel with significant wear resistance. The carbides are bonded together by the steel matrix.
The importance of carbide size
A knife steel with large carbides is generally very difficult to regrind, since the carbides crumble out of the edge and cause a 'saw edge' instead of a razor-sharp edge. Sandvik produces knife steels with fine carbides which enable excellent edge sharpness.
Combination of knife steel properties
The table shows combinations of knife steel properties for different classes of steel. Note that corrosion is detrimental for the cutting edge. Consequently the lack of sufficient corrosion resistance also affects knife performance and not only the esthetics of the blade.
