Leading Hastelloy B2 Bar Manufacturer
Hastelloy B2 bar is a premium nickel-based alloy. It is known for its exceptional corrosion resistance in aggressive environments. This material is ideal for several industrial applications.
The alloy contains a high percentage of nickel (65%), molybdenum (28%), and a small amount of iron, chromium, & other elements. That’s why this alloy imparts excellent resistance to corrosion caused by acids, alkalis, & reducing agents.
You can use Hastelloy B2 bar in any application you want, for example Chemical processing, Petrochemical, Power generation, Oil and gas, Aerospace, Marine, Food processing, Automotive, Pulp and paper, Water treatment, Mining, Desalination and more.
At Tuolian, we offer bars in various sizes, lengths, and forms. The forms include round bars, flat bars, and hexagonal bars. They are produced in compliance with international standards, such as ASTM B335 & ASME SB335. That guarantees reliable & consistent performance.
For your next Hastelloy B2 bar requirements, we got you covered. We offer competitive pricing & flexible delivery options. Our company can accommodate custom orders based on specific requirements.
