The Difference Between 304j1 Modification And 304 And 304j1
As we all know, 304J1 is 304 copper material, mainly used for deep processing, and also belongs to the nickel-saving series. Compared with traditional 304, 304J1 modification has more nickel-saving advantages. Now, it has excellent performance-price ratio advantages and is favored in the market. unanimously praised by the majority of merchants.
However, some merchants are concerned about the impact of saving nickel on the performance of their joints.
Now, let’s take a closer look at the parameters of 304j1 and 304j1 modification.

4. Features:
(1) The appearance surface and the previous 304j1 no big difference, and 304 also no big difference;
(2) NI content reduction, deep processing performance must not be compared with the original 304j1.
To sum up, if the user is the purchase of deep materials, then the comparison is not suitable for the choice of 304j1 modified. Other uses, customers can try.
