Inconel 600

Alloy 625

Alloy 625 is a Nickel-Chromium alloy used for its high strength, excellent fabricability and outstanding corrosion resistance.

Service temperatures range from cryogenic to 1800° F. Alloy 625 strength is derived from the stiffening effect of molybdenum and columbium on its Nickel-Chromium matrix; thus precipitationhardening treatments are not required. This combination of elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.

Inconel 625 Characteristic:

Inconel 625 Seamless Tubes Metallurgical structure

Inconel 625 Tubing Inonel 625 Pipe is face-centered cubic lattice structure. Dissolve out the carbon granule and instability quaternary phase, then change it to stability Ni3 (Nb,Ti) trimetric lattice around 650℃ after a long time heat preservation. nickel-chromium content will strength the mechanical performance in the state solution while suppress the plasticity

Inconel 625 Seamless Tubes Corrosion resistance

625 own a very good corrosion resistance in many media, especially with excellent resistance to pitting, crevice corrosion, intercrystalline corrosion, and erode in oxide, also good resistance to inorganic acid corrosion, such as nitric acid, phosphoric acid, sulfuric acid and hydrochloric acid. 625 can resist the alkali and organic acid corrosion in the oxidation and reduction environment. Effect resists the chloride reduction stress corrosion cracking. Normally no corrosion in the sea-water and industry environments since high corrosion resistance to the sea-water and salting liquid,as well as in high temperature, without sensitivity during welding. 625 have the resistance to oxidation and carbonizing in the static and cycle environments, also hacve the resistance the chlorine corrosion.

Typical Applications

Motorsport applications for Inconel 625 include:

【H】 Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

【H】 Cast basalt lined steel pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

【H】 Ceramic Tile Lined Pipes

Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.

【H】 Rare earth alloy wear-resistant pipe

The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.

【H】 Tubes Erosion Shields

Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.

【H】 ASTM A213 T91 Alloy Tube

The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
