Quantity
Our Nickel Based Alloy Allen Bolt is manufactured from highly corrosion-resistant nickel-based alloys, with sizes ranging from 3/8 to 1 inch and lengths from 30 to 800 mm. With a hardness of 150 to 200 HB and compliance with international standards such as ASME and EN, its exceptional corrosion resistance and high strength make it widely used in demanding environments such as shipbuilding, nuclear power, chemical processing, oil and gas, and industrial equipment, where it serves as the preferred choice for reliable connections.
Thanks to its unique alloy composition and microstructure, the Nickel Based Alloy Allen Bolt excels in corrosion resistance, capable of withstanding a variety of harsh corrosive environments, including acids, alkalis, salts, and both oxidizing and reducing media.
1. Acid Resistance
The Nickel Based Alloy Allen Bolt exhibits excellent corrosion resistance to various acidic media, particularly in strong acid environments.
The Nickel Based Alloy Allen Bolt exhibits excellent corrosion resistance to various acidic media, particularly in strong acid environments.
Sulfuric Acid Environment: Inconel 625 shows a corrosion rate of less than 0.1 mm/year in 98% concentrated sulfuric acid, and only 0.01 mm/year in a 10% sulfuric acid solution. Hastelloy C-276 also demonstrates a corrosion rate of less than 0.1 mm/year in 50% sulfuric acid at high temperatures (93°C).
Hydrochloric Acid Environment: In boiling 20% hydrochloric acid, Inconel 625 has a corrosion rate of 0.5 mm/year, while Hastelloy C-276 exhibits even higher corrosion resistance with a rate of only 0.25 mm/year.
Nitric Acid Environment: The Nickel Based Alloy Allen Bolt performs exceptionally well in nitric acid, with Inconel 625 showing a corrosion rate of less than 0.02 mm/year in 65% nitric acid, even at high temperatures.
