The Fasteners Mart, Mumbai, India, is a renowned manufacturer and supplier of high-quality ASTM A182 F55 Fasteners. Our F55 fasteners are made from super duplex stainless steel, which offers superior strength, corrosion resistance, and performance in aggressive environments. These fasteners are suitable for oil & gas, petrochemical, and marine applications and can withstand high-pressure, high-temperature conditions. With great dedication to quality and precision, The Fasteners Mart ensures all products to be of international quality, yielding secure and enduring fastening solutions to Indian customers and the entire globe.
ASTM A182 F55 Fasteners are manufactured from super duplex stainless steel, which is typically composed of 50% ferrite and 50% austenite and includes 25-26% chromium, 6-7% nickel, 3-4% molybdenum, and small amounts of nitrogen, manganese, and carbon. This provides them with excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive environments. F55 fasteners exhibit mechanical strength with greater tensile strength of 800 MPa and yield strength of 550 MPa. They exhibit better toughness as well as high temperature resistance, which makes them applicable for harsh service in the oil & gas, petrochemical, and marine industries.

ASTM A182 F55 Fasteners are used in high-strength, corrosion-resistance, and long-life applications with rough environments in industries. Typical uses are oil & gas exploration, petrochemical, and marine, where fasteners are exposed to high pressure, temperature, and corrosive medium. They are ideally suited for critical equipment such as heat exchangers, pressure vessels, reactors, and pipelines. Their increased resistance against chloride stress corrosion pitting and cracking makes them ideal for offshore platforms, desalination plants, and power generation facilities. ASTM A182 F55 fasteners ensure long-term stability and performance in tough industrial conditions.
ASTM A182 F55 fasteners are packaged and inspected for reliability and longevity. ASTM A182 F55 fasteners are usually packaged with corrosion-proof materials, such as steel drums or plastic, to prevent damage from the environment during transit. Each lot is extensively tested for tensile strength, hardness, and chemical composition to ensure adherence to ASTM standards. Dimensional inspection and visual tests are also performed to ensure proper manufacture. Only those fasteners that clear all the quality tests are considered fit for dispatch.
