Super Duplex Washers
Jinnox Bolt is a reputable super duplex washers manufacturer that has a history of quality production of super duplex washers, which are needed in harsh industrial environments where toughness, corrosive resistance, and longevity are required. These washers are made of super duplex stainless steel and are more resistant to pitting, crevice corrosion and stress corrosion cracking. They are designed to be used in high-pressure, high-temperature, and harsh environments, with chemicals hence suitable in oil and gas applications, marine, petrochemical, power generation, and heavy engineering applications. Precision production guarantees uniform distribution of the load, lessening of the bolts, and long life span of assemblies, which can safely and efficiently function in the most challenging conditions. Duplex Washers are also a complementary solution to applications that need slightly different mechanical or corrosion properties.
We have varying sizes, finishes,s and custom specifications of our super duplex washers that can fit the world standards and project requirements. The buyers also have access to quality products, competitive prices, and a reliable supply of the products, both small and bulk, through an effective B2B platform. Its performance, safety, and long-term value are all exemplified with tight control of quality and tracking of materials by every washer.
