Corrosion resistant alloy

Corrosion-resistant alloy is a kind of metal anti-corrosion material, which is a kind of special alloy, but it cannot be used in fluorine-containing environment. Compared with non-metallic anti-corrosion materials, metal anti-corrosion materials mainly include iron-based alloys (corrosion-resistant stainless steel); nickel-based alloys (Ni-Cr alloys, Ni-Cr-Mo alloys, Ni-Cu alloys, etc.); active metals .

Available Product Forms:

Pipe, tube, sheet, strip, plate, round bar, flat bar, forging stock, hexagon and wire.

1. Corrosion-resistant stainless steel

Mainly refers to the ordinary 300 series stainless steel 304 that is resistant to corrosion by the atmosphere or seawater, the most common corrosion-resistant alloy Hastelloy 316L, 317L, etc.; austenitic stainless steel 904L, 254SMO with strong corrosion resistance; dual-phase steel 2205, 2507 etc.; corrosion-resistant alloy 20 alloy containing CU, etc.

2. Nickel-based corrosion-resistant alloys

Mainly Hastelloy and NI-CU alloys, etc. Since the metal NI itself is a face-centered cubic structure, the crystallographic stability enables it to accommodate more alloying elements than FE, such as CR, MO, etc., so as to achieve resistance At the same time, nickel itself has certain anti-corrosion ability, especially the ability to resist stress corrosion caused by chloride ions. In strong reducing corrosive environments, complex mixed acid environments, and solutions containing halogen ions, nickel-based corrosion-resistant alloys represented by Hastelloy have absolute advantages over iron-based stainless steels.

3. Active Metals

Typical representatives with good corrosion resistance are TI; ZR; TA, etc. The most typical representative is TI; titanium has a wide range of applications, mainly used in some corrosive environments that stainless steel cannot adapt to.

Principle of corrosion resistance of titanium materials: In an oxidizing atmosphere, a dense oxide film is formed to provide protection; therefore, it is generally not used in corrosive environments with strong reducibility or high sealing properties. At the same time, the application temperature of titanium materials is generally less than 300 degrees Celsius. It is important to note that none of the active metals can be used in fluorine-containing environments.
