❓Frequently Asked Questions:
Can I use J4 instead of J1?
Yes, J4 is a highquality material. However, you should assess whether the additional cost is necessary for your specific production process.
Which grade is closest to 304?
J4 is the closest option. If budget allows, J4 offers the most reliable performance for manufacturers looking to transition from 304 to a more costeffective solution.
Is 201 J4 as good as 304?
J4 represents the closest alternative to 304 in the 201 series. While it has less corrosion resistance than 304, its mechanical formability is very similar, making it the preferred choice for costsaving in kitchenware manufacturing.
Why is 201 J2 cheaper than J4?
Copper is an expensive alloy element. By reducing the copper content, the production cost of J2 is significantly lowered, but its formability is correspondingly affected.
Is J3 better than J1?
Yes. J3 has stronger corrosion resistance and better polishing performance, making it the most costeffective option.
Can 201 J series be used outdoors?
It is suitable only for dry, non-coastal environments. Otherwise, it is recommended to use the 304 grade.
