Product Description


Duplex stainless steel wire, also known as austenitic-ferritic stainless steel wire, is a series of grades with approximately equal proportions of ferrite and austenite, and its structure contains a mixture of austenite and ferrite. It has two-phase properties, excellent corrosion resistance, and high mechanical strength. Duplex stainless steel wire has high chromium content (19%-28%) and low to moderate nickel content (0.5%-8%).

Production Process and Feature


Bright surface

High corrosion resistance;

Good formability and processability;

The first class is a low-alloy type, the agent grade is UNSS32304 (23Cr-4Ni-0.1N), the steel doesn’t include aluminum, the pitting corrosion resistance is equal, the PRE value is 24 to 25, and it may replace AIS304 (0Cr18Ni9) in relation to stress corrosion resistance Or 3160C17N12M02) use.

The next category is a moderate alloy type, the agent grade is UNSS31803 (22Cr-5Ni-3Mo-0.15N), and the PRE worth is 32-33. Its corrosion resistance is between AISI316L (00Cr17NiM2) and 6%Mo+N austenite Between stainless steel.

The third category is a high-alloy type, generally containing 25% Cr, also containing molybdenum and nitrogen, and some also containing copper and tungsten. The standard grade is UNSS32550 (25Cr-6Ni-3Mo-2Cu-0.2N), and the PRE value is 38~ 39. The corrosion resistance of this kind of steel is greater than that of 24c duplex stainless steel.

The fourth group is super duplex stainless steel type, including high molybdenum and nitrogen, standard grades are UNSS32750 (25Cr-7Ni-3b-0.3N), and some also contain tungsten and aluminum, and the PRE worth is greater than 40, which is applied to harsh networking Conditions, with great comprehensive corrosion resistance performance, akin to super austenitic stainless steel

Application


Special purpose stainless steel wire.

Chrysler automotive antennas and antennas for the US market of major brands, as well as special uses such as straps, eyeglass frames, headphone cords, and bust lines.

Uses of duplex stainless steel

Duplex stainless steel has been widely used in various industrial fields, such as pulp and paper, onshore and offshore oil and gas industry, chemical industry Study processing industry, transport industry (chemical tanker and tanker), food and pharmaceutical industry, and construction industry.

Different industrial equipment and pipelines, etc. In most programs, duplex stainless steel is considered a cost-effective material Fill the gap between normal austenitic stainless steel such as 316 and high-alloy austenitic stainless steel Although it is generally believed that duplex stainless steel is used because of its corrosion resistance to chemical products, such as urea and fertilizers Some media encountered in production, organic acid production, and processing of hydrogen sulfide-containing natural gas, the most significant application is used there.

Equipment like heat exchangers, condensers, and assorted containers.
