In duplex stainless steel, the ferrite phase and the austenite phase account for about half in its solid solution structure, and the lesser half of the phase should reach 30%! It combines the characteristics of austenitic and ferritic stainless steels. In the case of low C content, the Cr content is 18%-28%, and the Ni content is 3%-10%.

It is said that the price of dual-phase steel S32001 is more than 1,000 more expensive than 201 high copper material, but more than 5,000 cheaper than 304. Yesterday, Dingxin 304 narrowband agent reported 17,000 including tax, which means that the price of S32001 should be around 12,000 yuan/ton, which is subject to the official price!

And yesterday, the tax-included price of Jiugang 2205 four-foot trimming was around 33,000 yuan/ton! That is to say, the price difference between S32001 and 2205 is around 20,000 yuan/ton.

Performance
"Dual Phase Steel S32001" VS Dual Phase Steel 2205
Although the two prices are far apart, it is said that the S32001 has the characteristics of corrosion resistance, high rust resistance, high strength, and high cost performance. It is suitable for conventional welding methods such as electrode arc welding and submerged arc welding. It also has the same characteristics of austenitic and ferritic stainless steel as 2205.

Advantages and Features:
S32001 welded pipe is more corrosion-resistant than 304 welded pipe and has better polishing performance. It can be used in engineering and export is no problem! But the only thing: can't do food grade tube
S32001 has been used in the welded pipe of the terminal guardrail and the square pipe of the shipping container, and has achieved satisfactory results!
