Hastelloy B-2 Round Bar Heat Resistant Alloy Rods for Petrochemical & Pharmaceutical Equipment
1. Product Introduction
Hastelloy B-2 round bars, a premium nickel - molybdenum (Ni - Mo) heat - resistant alloy rod, are specifically engineered to meet the rigorous demands of the petrochemical and pharmaceutical industries. This alloy exhibits exceptional resistance to reducing environments, making it an ideal choice for applications where other materials often fail due to corrosion.
In the petrochemical sector, these round bars are widely used in equipment such as reactors, heat exchangers, and piping systems that handle harsh media like hydrochloric acid, sulfuric acid, and various organic compounds at elevated temperatures. Their ability to maintain structural integrity even in high - temperature (up to 1093°C / 2000°F) and high - pressure conditions ensures long - term reliability and minimizes downtime for maintenance.
For the pharmaceutical industry, where purity and hygiene are of utmost importance, Hastelloy B-2 round bars offer excellent resistance to a wide range of pharmaceutical intermediates and cleaning agents. They do not leach harmful elements into the process, ensuring compliance with strict industry regulations and safeguarding the quality of pharmaceutical products. Additionally, the smooth surface finish of the round bars facilitates easy cleaning and sterilization, further enhancing their suitability for pharmaceutical equipment manufacturing.

3. Executive Standards
Hastelloy B-2 round bars adhere to a series of international and industry - recognized standards to ensure consistent quality and performance. The key standards include:
- ASTM B335: This American Society for Testing and Materials (ASTM) standard specifies the requirements for nickel - alloy rod and bar, including chemical composition, mechanical properties, dimensional tolerances, and testing methods. Hastelloy B-2 round bars manufactured in accordance with ASTM B335 undergo strict quality control to meet the highest industry standards.
- ASME SB - 335: Developed by the American Society of Mechanical Engineers (ASME), this standard is closely related to ASTM B335 and is widely used in the design and manufacturing of pressure vessels and piping systems in the petrochemical and power industries. Compliance with ASME SB - 335 ensures that the round bars are suitable for critical pressure - containing applications.
- EN 10095: The European standard for heat - resistant steels and nickel - based alloys, EN 10095 sets out the requirements for the chemical composition, mechanical properties, and heat treatment of these materials. Hastelloy B-2 round bars meeting EN 10095 standards are accepted in European markets and other regions that recognize European standards.
- JIS H4552: The Japanese Industrial Standard for nickel and nickel - alloy bars, JIS H4552 specifies the technical requirements for nickel - alloy bars used in various industrial applications. This standard is commonly referenced in Japanese - owned manufacturing facilities and in markets where Japanese technical standards are prevalent.
4. Similar Grades
While Hastelloy B-2 is a highly specialized alloy, there are several similar grades available in the market that offer comparable properties and can be considered as alternatives in certain applications. The main similar grades are:
- Hastelloy B - 3: An improved version of Hastelloy B - 2, Hastelloy B - 3 has a lower carbon content and optimized silicon and iron levels. This modification enhances its resistance to intergranular corrosion and improves its weldability. It is particularly suitable for applications involving high - temperature exposure and welded structures, such as in the petrochemical industry's high - temperature reactors.
- Ni - Mo Alloy 200: Also known as Nickel 200, this pure nickel alloy has good corrosion resistance in reducing environments and is often used in chemical processing equipment. However, compared to Hastelloy B - 2, it has a lower molybdenum content, resulting in slightly lower resistance to strong reducing acids like hydrochloric acid. It is more suitable for less severe corrosion environments.
- Alloy C - 276: Although Alloy C - 276 is a nickel - chromium - molybdenum (Ni - Cr - Mo) alloy (different from the Ni - Mo system of Hastelloy B - 2), it offers excellent all - round corrosion resistance, including resistance to both reducing and oxidizing environments. In some cases where the corrosion environment is complex (containing both reducing and oxidizing agents), Alloy C - 276 can be a viable alternative. However, it has a higher chromium content, which may lead to higher costs compared to Hastelloy B - 2.
