Duplex Stainless Steel Seamless Pipe & Tube

Product Features:
The microstructure is composed of a perfect blend of approximately 50% ferrite and 50% austenite, utilizing a nickel-saving alloy design featuring "low nickel, high chromium, and added molybdenum and nitrogen".

Benefits: 
Combining the high strength of ferrite with the excellent toughness of austenite; High thermal conductivity, low coefficient of linear expansion, very close to carbon steel; In harsh media such as chloride ions and hydrogen sulfide, it has excellent resistance to corrosion fatigue and wear corrosion. 

Performance:
The yield strength can reach 400-550 MPa, which is twice that of ordinary austenitic stainless steel; The PREN value (equivalent to pitting corrosion resistance) has significantly increased, and the ability to resist local corrosion is outstanding.

Advantages:
High strength, weight reduction, cost reduction and efficiency improvement: The doubled yield strength significantly reduces the wall thickness of the equipment, not only achieving lightweight design, but also directly saving you considerable material costs. 
Perfect solution to stress corrosion cracking pain points: Completely immune to the stress corrosion cracking (SCC) problem of conventional stainless steel in chloride ion environments, it is a breakthrough tool for high demand scenarios such as marine engineering and oil and gas transportation.

About Us
Anhui Yingsheng Steel Pipe Manufacturing Co., Ltd.

Anhui Yingsheng Steel Pipe Manufacturing Co., Ltd. is located in Jixi County, Anhui Province, one of the birthplaces of Huizhou culture and a famous historical and cultural city, about 50 kilometers away from Mount Huangshan. It was established in August 2010 with a registered capital of 158 million yuan. The plant covers a total area of more than 40000 square meters, with a total investment of nearly 120 million yuan, and an annual output of more than 22000 tons of stainless steel seamless steel pipes.

The company has more than 40 advanced stainless steel seamless pipe production lines (cold drawing and cold rolling units) in China, which can produce stainless steel and nickel based alloy seamless pipes with an outer diameter of 6-630mm × Wall thickness (1-80mm) × Length (1000-300mm); The main materials include: 304, 304L, 304H, 321, 321H, 316, 316L, 316LMOD, 317L, 310S (2520), 347H, 904L, duplex stainless steel, Inconel 600, Incoloy 800, Incoloy 800H, Hastelloy C-276, and Monel 400.

The company can organize production according to standards such as GB, ASTM/ASME, JIS, DIN, GOST, SH, HG, DL, etc., or according to special customer needs. The tube billets come from brand steel mills such as Baosteel, Taiyuan Iron and Steel, Huaxin Lihua, Yongxing Special Steel, and Qingshan.

The products are widely used in fields such as petroleum, chemical industry, chemical fiber, medicine, machinery, smelting, aerospace, papermaking, food, shipbuilding, environmental protection, boilers, heat exchangers, pressure vessels, condensers, water conservancy, electricity, etc., and have gained a good reputation in the industry.

The company has passed ISO9001:2015, EU PED (2014/68/EU) certification, AD2000W0 certification, TS A1 certification for special equipment (pressure pipeline) production and manufacturing license, BV French Classification Society certification, occupational health and safety management system certification, environmental management system certification, and multiple industry qualification certifications. The products are highly praised by users.
