Material Properties – Nickel 200 Bolts

Nickel 200 is a commercially pure wrought nickel material distinguished by its exceptionally high nickel content. It offers a unique combination of outstanding corrosion resistance to a wide range of reducing and caustic media, excellent mechanical properties from cryogenic to moderate temperatures, and very good thermal and electrical conductivity. As a non-age-hardenable material, its strength is primarily achieved through cold working.

آهن (آهن)	≤ 0.40%	Maximum allowable impurity, contributes to ferromagnetism.
منگنز (Mn)	≤ 0.35%	Maximum allowable impurity.
کربن (C)	≤ 0.15%	Controlled impurity. Higher levels can lead to graphitization and embrittlement at temperatures above ~315°C.

Yield Strength (0.2% Offset): 480 – 690 MPa (70 – 100 ksi)
ازدیاد طول: 20% – 35%
Hardness: Rockwell B 75 – 95

Key Material Characteristics:

عملکرد در دمای پایین: Maintains excellent toughness and ductility at cryogenic temperatures, with no ductile-to-brittle transition. Ideal for LNG and cryogenic applications.
Magnetic Property: Ferromagnetic (exhibits magnetism) due to its high nickel purity.
Temperature Limit: Continuous service in oxidizing atmospheres is recommended up to approximately 315°C (600°F). For higher temperatures, Nickel 201 (low-carbon grade) should be used to avoid embrittlement.

Nickel 200 Bolts Typical Applications

Chemical and Petrochemical: Alkali evaporators, caustic handling equipment, organic synthesis reactors, fatty acid processing equipment.
Food and Pharmaceutical: Equipment requiring high purity, corrosion resistance, and easy cleaning, such as connections for critical piping and reaction vessels.
مهندسی دریایی: Seawater desalination plants, marine pumps and valves, seawater cooling systems, and other components resistant to brine corrosion.
Aerospace and Vacuum Technology: Engine components, fuel systems, high-vacuum equipment (due to its low vapor pressure and low gas permeability).
Energy and Nuclear Industry: Specific stages such as nuclear fuel processing and uranium refining (resistant to hydrofluoric acid corrosion).
Cryogenic Engineering: Liquefied Natural Gas (LNG) equipment, cryogenic storage tanks, superconducting research devices.
