ASTM A564 UNS S17400 Fasteners are high-strength stainless steel fastening components manufactured from precipitation-hardening stainless steel corresponding to UNS S17400, commonly known as 17-4 PH stainless steel. ASTM A564 covers hot-rolled and cold-finished precipitation-hardening stainless steel bars and shapes, which can be used as a material specification for producing precision-engineered fasteners. UNS S17400 combines corrosion resistance with high mechanical strength, making it suitable for fastening applications where conventional stainless steel grades may not provide the required strength.

ASTM A564 UNS S17400 Fasteners are commonly supplied in forms such as bolts, screws, nuts, studs, washers and other specially manufactured fastening components. The material can be heat treated to achieve different combinations of hardness, tensile strength and yield strength. This precipitation-hardening capability allows engineers to select an appropriate heat-treatment condition according to the requirements of the application.

The stainless steel composition of UNS S17400 includes chromium, nickel, copper and other controlled alloying elements that contribute to its corrosion resistance and precipitation-hardening characteristics. The alloy is particularly recognized for maintaining a useful balance between strength and corrosion resistance. Depending on the selected material condition and product requirements, these fasteners can be manufactured to precise dimensions, thread configurations, surface finishes and mechanical-property requirements.

Advantages of ASTM A564 UNS S17400 Fasteners

One of the primary advantages of ASTM A564 UNS S17400 Fasteners is their high strength-to-weight capability. Through suitable precipitation-hardening heat treatment, UNS S17400 can achieve significantly higher strength than many conventional austenitic stainless steel grades. This makes the fasteners suitable for assemblies exposed to substantial mechanical loading, vibration and demanding operating conditions.

Corrosion resistance is another important characteristic. UNS S17400 provides useful resistance to atmospheric corrosion and a variety of industrial environments. Its chromium content supports the formation of a passive surface, while the alloy composition provides a combination of corrosion resistance and mechanical performance. For applications requiring greater corrosion resistance, the actual environment, temperature, surface condition and heat-treatment condition should be evaluated before material selection.

ASTM A564 UNS S17400 Fasteners also offer good dimensional stability and machinability when processed using appropriate manufacturing practices. Their precipitation-hardening characteristics allow manufacturers to produce components with controlled mechanical properties after heat treatment. This is useful for engineered fasteners that require consistent performance across production batches.

Another advantage is their suitability for customized fastening requirements. These fasteners can be manufactured with different thread forms, diameters, lengths, head styles and configurations according to engineering drawings or applicable fastener standards. They can also be supplied with suitable surface finishes and inspection documentation when required by the purchaser.

The combination of strength, corrosion resistance, hardness and heat-treatment flexibility makes UNS S17400 a practical material for demanding industrial fastening systems. Proper selection of condition, dimensions, thread design and applicable product standards is important to achieve the required performance in service.

Industrial Applications of ASTM A564 UNS S17400 Fasteners

ASTM A564 UNS S17400 Fasteners Manufacturers produce precision fastening components for industrial assemblies where high mechanical strength and stainless steel corrosion resistance are important. These fasteners can be used in machinery, pressure-related equipment, pumps, valves, industrial processing systems and fabricated assemblies. Manufacturers can produce standard and customized components according to dimensional specifications, material requirements, heat-treatment conditions and inspection requirements.

ASTM A564 UNS S17400 Fasteners Suppliers provide fastening solutions for sectors such as oil and gas, petrochemical processing, chemical equipment, power generation, marine equipment and heavy engineering. Their high-strength characteristics make them useful for structural and mechanical connections where fastening components must withstand considerable loads. Selection should consider operating temperature, corrosive exposure, applied stresses and the required mechanical properties.

ASTM A564 UNS S17400 Fasteners Stockists maintain different sizes and configurations for industrial maintenance, replacement and project requirements. These fasteners can be used for pumps, valves, shafts, mechanical equipment, pressure systems and general engineering assemblies. Stock availability may vary according to size, finish, configuration and quantity, while non-standard dimensions can generally be produced against an approved technical specification.

ASTM A564 UNS S17400 Fasteners Exporters supply these stainless steel fastening components to international engineering, fabrication and industrial markets. They are used in applications involving high-strength mechanical connections, including aerospace-related equipment, marine systems, energy installations and specialized industrial machinery. Export orders can be supplied according to agreed dimensions, applicable standards, heat-treatment requirements, testing documentation and packaging specifications.

ASTM A564 is a material specification associated with precipitation-hardening stainless steel bars and shapes, while the dimensional and performance requirements for an individual fastener may also be governed by a separate fastener, dimensional or application-specific standard. Therefore, buyers should clearly define the material specification, fastener standard, dimensions, thread type, heat-treatment condition, testing requirements and certification requirements in the purchase specification.

Real Fasteners supplies ASTM A564 UNS S17400 Fasteners for industrial requirements with attention to material traceability, dimensional accuracy and application-specific specifications. Depending on project requirements, fasteners can be supplied in standard or customized configurations with relevant documentation and inspection requirements.

Material Options for ASTM A564 UNS S17400 Fasteners

UNS S17400 is a precipitation-hardening martensitic stainless steel commonly identified as 17-4 PH. The final properties of fasteners manufactured from this alloy depend strongly on the processing and heat-treatment condition. Buyers should therefore specify the required condition and mechanical properties rather than relying only on the alloy designation. Common material conditions used for 17-4 PH include solution-treated and precipitation-hardened conditions, with the selected condition affecting strength, hardness and toughness.

Manufacturing may involve cold or hot forming, machining, threading and subsequent heat treatment depending on the fastener design and required properties. Precision machining is important for producing accurate threads, bearing surfaces and dimensional tolerances. For critical applications, purchasers may request material certificates, dimensional inspection, mechanical testing, hardness testing and other quality-control documentation.
