What is 304D Stainless Steel

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.

How much is appropriate for pricing?

Between J4 and 202 (hot rolling), if the value is J4-8400, 202-11700 (excluding tax), how much is it priced?

It is said that once the price of J1 hot rolling +2500 of 201 was considered. In other words, if J1 does not include a tax of 7900, then it does not include tax and is 10,400 yuan / ton;

The second statement said that it may be set to 304 hot-rolling-3000, according to the market does not include tax 13500 (yesterday market price) of Qingshan material, minus 3000 is 10500.

In fact, the error between the two prices is not large. However, from today's Qingshan individual agent quotation, the tax price of 304D is 11400 (cold rolled sheet 11700, thick plate 11900) and 304 hot rolling including tax 15000 calculation, the price difference is 3600.

If you follow 9 points, the tax is not around 13400, and the spread is 3250. There is a big error.
