Despite 3Cr13 stainless steel strip and 440 stainless steel strip being made from almost same material which is the stainless steel, these two have a slight difference in their element composition.
The alloy elements in 3Cr13 stainless steel strip and 440 stainless steel strip are the same although they vary in amount. 440 stainless steel strips contains more chromium and carbon when compared to 3Cr13 stainless steel strip.
However, the 440 stainless steel contains less silicon and manganese than 3Cr13 stainless steel strip. They both contain the same amount of nickel.
440 stainless steel strips are known to be much harder due to the high amount of chromium and carbon content.
The slight difference in the hardness ensures 440 stainless steel strips are capable of achieving better edge retention and wear resistance than the 3Cr13 stainless steel strip.
In case you are in the market of selling products with superior cutting features, then it is advisable that you go for the 440 stainless steel.
Resistance to wear and edge retention is the only features 440 stainless steel strip has more than the 3Cr13 stainless steel strips.
