Traditionally, stainless steel 2E is generally a product only available in the European standard, which means that the black skin is directly rolled and then annealed and pickled. The surface is between NO.1 and NO.2B.
There are currently four domestic steel mills producing stainless steel 2E surfaces:
1. Angang Lianzhong
Ansteel Lianzhong’s 2E surface is the earliest technical product in China, and it is also the most skilled in technology. It is traditionally classified as a cold-rolled product. It is reported that the thinnest thickness of Ansteel Lianzhong is 0.8, and all of them are for Hanyang, not takeaway.
2.Fuxin Special Steel
The 2E surface of Fuxin Special Steel is different from other manufacturers in that it is only hot-rolled and pickled, with the thinnest thickness of 1.35, which can be used as a direct tube plant material.
3. Fujian Hongwang
Fujian Hongwang three-rolling line can seamlessly and automatically switch, not only can produce 2E, but also 2B; acid can be adjusted online; hot-rolled material can be up to 1.1 thickness; triple-rolling and continuous withdrawal are complete There is no segmentation, the black skin is directly rolled, rolled and then annealed and pickled.
4.Beihai Chengde Metal Rolling Co., Ltd
On March 26 last year, Beihai Chengde Metal Rolling Co., Ltd. Direct Rolling Annealing and Pickling Line (DRAPL) successfully produced the first hot-rolled white coil (No.1/2E), which was annealed and pickled The line is designed to produce 700,000 tons of 200-series and 300-series stainless steel hot-rolled white coils with a thickness of 1.1 to 2.2 mm. After the latest technological transformation, the thinnest surface of Beihai Chengde 2E can be 1.0, and the direct pressure is 0.3.
