Super Duplex ASTM A479 UNS S32750 fasteners are known for their excellent machinability and ease of fabrication. With high chromium and nickel content, these fasteners, including nuts, bolts, washers, and screws, offer impressive corrosion resistance and superior oxidation protection. They maintain a significant portion of their strength at room temperature, making them ideal for demanding environments.

Super Duplex ASTM A479 UNS S32750 bolts excel in various conditions due to their robust composition, while the washers can withstand temperatures up to 1100 °C in dry air. However, care must be taken with the screws, as they can be sensitive to thermal shock and require careful handling during hot-working processes. The stud bolts are effective at temperatures reaching 1150 °C for continuous operations and 1035 °C for intermittent use.

Super Duplex fasteners are commonly utilized in high-temperature applications such as oven linings, boiler baffles, kilns, and combustion tubes. ASTM A479 Super Duplex S32750 fasteners are suitable for use in environments where temperatures exceed 550 °C, providing oxidation resistance up to 2000 °F and moderate strength at elevated temperatures. Whether for furnace components or refractory anchor bolts, Super Duplex ASTM A479 UNS S32750 fasteners deliver reliability and performance in challenging conditions.

Explore our extensive range of Super Duplex Steel Products, including pipes, tubes, flanges, and fittings, all known for their outstanding corrosion resistance and durability in challenging environments.

FAQ’s About ASTM A106 Grade B Pipes

What is ASTM A106 Grade B pipe?

ASTM A106/A106M Grade B is a seamless carbon steel pipe specification intended for high-temperature service. The exact project suitability depends on the governing piping code, design conditions and purchase specification.

What is the difference between ASTM A106 Grade B and ASTM A53 Grade B?

ASTM A106 Grade B is a seamless high-temperature-service pipe specification. ASTM A53 Grade B covers welded and seamless pipe for mechanical and pressure applications and ordinary steam, water, gas and air service. Select the specification required by the project and design code.

What sizes does Kalpataru supply?

The current brief lists a Kalpataru supply range of 1/2 to 36 in NPS and Schedule 10 to XXS, subject to size and availability. ASTM A106/A106M itself has a wider standard scope.

What is the maximum temperature of ASTM A106 Grade B pipe?

Do not use one universal maximum temperature from the ASTM material specification. Allowable service depends on the design code, pressure, wall thickness, allowable stress and project conditions.

Is ASTM A106 Grade B seamless or welded?

ASTM A106/A106M is a seamless carbon steel pipe specification. Do not describe ERW, LSAW or other welded pipe as ASTM A106 product construction.

What tests are required for ASTM A106 Grade B pipe?

The specification includes mechanical testing and bend/flattening testing as applicable, together with hydrostatic and/or nondestructive electric testing requirements. The exact inspection package should match the current ASTM edition and purchase order.

What documents can be supplied?

Orders can be supplied with EN 10204 3.1 MTC and, where applicable and agreed, IBR documentation, third-party inspection and project-specific test reports.

How is ASTM A106 Grade B pipe priced?

Price depends on NPS, schedule or wall thickness, length, quantity, origin/mill, testing/certification, coating/end preparation and delivery destination. Send the full requirement for a size-wise quotation.
