Alloy 200 & Alloy 201 are nickel alloys which have been combined into one with dual certified chemistry.
Alloy 200, also known as Hastelloy C-200, is a versatile and widely recognized family of austenitic nickel-chromium-molybdenum alloys. Known for its exceptional resistance to a broad range of corrosive environments, it has become an industry staple for applications where high performance and reliability are critical.
It offers excellent corrosion resistance, good mechanical, magnetic and magnetostrictive properties and useful thermal and electrical conductivities.
Alloy 200 & Alloy 201 are nickel alloys which have been combined into one with dual certified chemistry. This means that customers receive the required characteristics from both alloys in a single solution. Alloy 200/201 offers exceptional resistance to caustic alkalis and good mechanical properties over a wide temperature range. The alloy is used in such applications as fluorine and sodium hydroxide production as well as heat exchangers and pressure vessels.
The result is an alloy which benefits from the required characteristics from both alloys in a single solution. Alloy 200/201 offers exceptional resistance to caustic alkalis and good mechanical properties over a wide temperature range. The alloy finds use in such applications as fluorine and sodium hydroxide production as well as heat exchangers and pressure vessels.
Alloy 200 / 201 is similar in strength to mild steel in the annealed condition. The alloy offers exceptional resistance to caustic alkalis and good corrosion resistance in neutral and moderately reducing environments. Alloy 200/201 displays good mechanical properties over a wide temperature range.

Commercial applications for this engineering material include:
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
