Product Introduction


Hyper Duplex Stainless Steel is a type of stainless steel characterized by its superior corrosion resistance, high strength, and excellent mechanical properties. It belongs to the family of duplex stainless steels, which are known for their dual-phase microstructure consisting of both austenitic and ferritic phases. However, what sets Hyper Duplex apart is its increased chromium, molybdenum, and nitrogen content, further enhancing its corrosion resistance and strength.


Due to its exceptional corrosion resistance, Hyper Duplex Stainless Steel finds extensive applications in demanding environments where conventional stainless steels may fail. Industries such as offshore oil and gas, marine, chemical processing, and desalination plants heavily rely on Hyper Duplex fasteners to withstand aggressive media, such as chloride-containing solutions and seawater.


Moreover, its high strength and toughness make it ideal for critical structural components and load-bearing applications, offering reliability and safety in challenging operational conditions. Whether it's subsea equipment, marine structures, or chemical processing facilities, Hyper Duplex Stainless Steel fasteners play a crucial role in ensuring operational efficiency and asset integrity.


Hyper Duplex Stainless Steel fasteners represent a cutting-edge solution for industries requiring superior corrosion resistance, strength, and durability. At [Your Company Name], we specialize in manufacturing high-quality Hyper Duplex fasteners, leveraging our expertise and advanced production capabilities to deliver reliable solutions that meet the most stringent requirements of our clients. Trust us to provide you with fasteners that ensure optimal performance and longevity, even in the harshest environments.

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
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.

1
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.

1
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.

Non-conforming goods management
According to the process of JMhardware's non-conforming products handling, pick or scrap. And the problem of rectification and tracking reasons to ensure that non-conforming products will not flow into the market.

These quality control measures constitute JM Hardware's quality management system, and we are constantly striving to improve the quality of our products and are committed to meeting the needs of our customers. We believe that quality control is the key to our success.
