1. Is there any difference between the manufacturing process of 304 stainless steel square pipe and 304 stainless steel round pipe?

Basically, there is no difference, but will produce 304 stainless steel round pipe first, then pressed out the 304 stainless steel square pipe with a mold.

2. What is mold fee?

Mold fee is for the customized size 304# stainless steel pipe. As there is no same mold to make the stainless steel products. For the special mold, we have to charge the mold fee.

3. Is 304 stainless steel magnetic?

304 stainless steel pipe belongs to austenitic stainless steel. In theory, austenitic stainless steel is not magnetic, while martensitic and ferritic stainless steel will be magnetic.

4. Advantages of 304 stainless steel?

304 stainless steel has the advantages of common corrosion resistance, beautiful shape and relatively cheap price.

5. What are the states of 304 stainless steel surface?

There are polished, brushed coating etc.

6. Why does 304 stainless steel have uneven wall thickness?

Because of the existence of error makes it impossible for 304 stainless steel to form a perfect circle, but it is allowed within the tolerance range.

7. What is eccentricity?

Eccentricity should be said to be a serious uneven wall thickness of 304 stainless steel, that makes it look like the center of the circle is displaced.
