Hastelloy B-2 / N010665 / Hex Bolt
JM Hastelloy B-2 (N10665) Corrosion-Resistant Hex Bolt
The JM Hastelloy B-2 (UNS N10665) Corrosion-Resistant Hex Bolt is a high-performance fastener made from Hastelloy B-2, a nickel‑molybdenum alloy known for exceptional resistance to reducing acids and chloride-bearing environments. This hex bolt offers strong mechanical properties, good ductility, and reliable dimensional accuracy for secure assemblies. It resists pitting and crevice corrosion in harsh chemical conditions where standard stainless steels fail.
Usage scenarios:
- Fastening components in chemical processing plants, especially where hydrochloric or other reducing acids are present.
- Assembly and repair of valves, pumps, reactors, and piping systems in petrochemical and oil & gas facilities exposed to chloride-rich or brine environments.
- Any application requiring long-term, corrosion-resistant bolting in aggressive, reducing media—such as acid pickling lines, pickling tanks, and specialty industrial equipment.

Product Introduction
Hastelloy B-2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Hastelloy B2 provides resistance to pure sulfuric acid and a number of non-oxidizing acids. The alloy should not be used in oxidizing media or where oxidizing contaminants are available in reducing media. Premature failure may occur if alloy B2 is used where iron or copper is present in a system containing hydrochloric acid.
Industry users like the resistance to a wide range of organic acids and the resistance to chloride-induced stress-corrosion cracking.
Hastelloy B2 resists the formation of grain boundary carbide precipitates in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat-affected weld zones have reduced precipitation of carbides and other phases to ensure uniform corrosion resistance.
Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

Quality Control
JM Hardware conducts product quality control in strict accordance with ISO 9001 standards to ensure that our products meet high quality standards. Below are our five quality control steps:

1
Incoming material control
We carry out strict incoming material control by conducting dimensional tests on each batch of raw materials and checking the raw material reports from the steel mills. This ensures that the raw materials we use are within specification and provide a reliable basis for production.

First part control
After the mold assembly is completed, we conduct a thorough inspection of the first production part and make detailed records. Only qualified first parts can be released to start mass production. This step ensures that the quality of the product meets the standard at the beginning.

Self-inspection by workers during mass production
In the mass production process, we require the workers of each machine to carry out self-inspection every hour. If any substandard product is found, we will immediately pick or scrap the production within this hour until the problem is solved and meets the standard of conformity, and then we can continue the production. This self-inspection mechanism helps to find and solve problems in time during the production process.

QC inspection during mass production
In addition, every two hours, the quality inspection personnel will carry out random inspection on the products of each machine. Only qualified products can continue to flow into the next production stage. If non-conforming products are found, we will take the same selection or scrapping measures and ensure that the problem is properly handled. This helps provide additional quality assurance.

Finished product control
Finally, after each batch of finished product is made, we conduct random inspections in proportion to the order. Qualified products will be packaged and put into storage, while unqualified products will be returned for further analysis and rectification. We insist on ensuring that the quality of our products meets high standards so that we can provide reliable products to our customers.
