Product Description

1: Brief Introduction Of 304D stainless steel pipe
304D is a new material that lanuched into the market recent,  its cost and performance are higher than 201 stainless steel (increasing
Cr, Ni, Cu content, reducing Mn content), but lower than 304 stainless steel (Ni content is not up to 8%).
Although the 304D has a chromium content of more than 18, its nickel content is only 2.8, and we know that the normal 304 nickel
content has to be more than 8. Not only that, its copper content is still low, and its manganese content is as high as seven, in a strict
sense, it cannot be related to 304 at all.
The industry believes that it may be more appropriate to define it as the D series. And D11 already exists, you may not be too much
to set a D7, D9. But you can't think of 18 chromes, you can get a 304 plus suffix, which is a bit too hot.
You must know that 304 has a national standard and the name cannot be confused at will. I am especially worried about the idea of
someone who has been branded with this steel.
