ASTM A194 7 / 7M Fasteners

What is ASTM A194 7 / 7M Fasteners

The American Society for Testing and Materials (ASTM) has established a specification called ASTM A194 7/7M that covers a variety of strong and durable fasteners, which are primarily used in the petrochemical, oil and gas, and power generation sectors where they have to endure extreme conditions.

Fasteners made according to the ASTM A194 7/7M standard are manufactured from a particular type of stainless steel, AISI 304 or 304L. This stainless steel alloy combines chromium, nickel, and other components that offer impressive protection from corrosion, even in hostile conditions. Including molybdenum in the 304L version further heightens its resistance to crevice and pitting corrosion.

One of the primary characteristics of ASTM A194 7/7M fasteners is their high strength in tension. The tension strength of a material is its capacity to deal with a strain before it breaks. The 7/7M standard guarantees these fasteners have the lowest tension strength of 75 ksi (kips per square inch), comparable to roughly 515 MPa (megapascals). This intensity permits them to endure high loads and high-pressure conditions without bending or demise.

Additionally, ASTM A194 7 / 7M fasteners greatly resist high-temperature exposure. They offer superior performance when exposed to up to 870°C (1600°F), retaining most of their mechanical properties. As such, they are ideal for use in intense environments, such as boilers, heat exchangers, and steam pipelines.

An important attribute of ASTM A194 7/7M fasteners is their outstanding anti-corrosion characteristics. Stainless steel grade 304L is especially resilient to corrosive agents such as acids, alkaline solutions, and chloride atmospheres. This trait guarantees that the fasteners will remain durable and dependable, even when in contact with corrosive materials or extreme weather.

Often, they are combined with either ASTM A193 B8 (stainless steel) or A320 L7 (carbon steel) fasteners to form a complete fastening system. Such fasteners are usually used in areas where dependability and safety are paramount.

At SumitImpex, we take extreme care when packaging ASTM A194 7/7M fasteners to ensure their safety during transportation and storage. We use the highest quality materials for the packaging and employ protective measures to guarantee that the fasteners reach their destination undamaged. Our packaging process demonstrates our commitment to providing these ASTM A194 7/7M fasteners in superb condition, ready to be used in a variety of industrial applications.
