Hastelloy B-3 Hex Flange Bolt
Hastelloy B3 Acid-Resistant Hex Flange Bolt (UNS N10675)
On a rain-slashed offshore deck or inside the hiss of a busy chemical plant, the Hastelloy B3 Acid-Resistant Hex Flange Bolt (UNS N10675) stands like a quiet guardian, holding critical joints against corrosive attack. Forged from premium Hastelloy B3, it laughs at acid and time—its hex flange grips tight, seals better, and promises long, steady service where ordinary bolts fail. Choose this bolt for confident, lasting strength and the peace of mind that your systems are safely held together.
Product features
The Hastelloy B3 Acid-Resistant Hex Flange Bolt (UNS N10675) is a high-performance hastelloy bolt made from B‑3 alloy that offers exceptional resistance to hydrochloric, sulfuric, phosphoric, formic and acetic acids across a wide range of concentrations and temperatures, while resisting pitting, stress‑corrosion cracking, knife‑line and weld heat‑affected zone attack. Its B‑3 chemistry provides greater thermal stability than B‑2 and the hex flange head integrates a built‑in washer for even load distribution, high clamp strength and simplified installation in demanding chemical processing and high‑temperature corrosive environments. Manufactured under ISO 9001 quality controls with comprehensive material testing and traceable test reports, this hex flange hastelloy bolt delivers reliable mechanical performance, long service life and reduced maintenance risk for critical industrial applications.

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:

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.
