Product details:
SS 347 / 347H Fasteners are columbium stabilized austenitic stainless steel fasteners with good general corrosion resistance. It has somewhat better corrosion resistance ability in strong reducing zone. Alloy 347/ 347H are also named as UNS S34700/ UNS S3406 grade. It has excellent resistance to intergranular attacks after exposure in the chromium carbide precipitation zone in the temperature ranges between 800- 1500 degree F. It has good creep strength temperature up to 1500 degree F. It also possesses good low-temperature properties in down toughness.
Alloy 347H is also UNS S3409 grade, it is the higher carbon version of alloy consist of 0.04- 0.10 ratio. It is developed for higher creep resistance and for higher strength at temperatures up to 1000 degree F. It is dual certified with the carbon content. These cannot be hardened by heat treatment process, only harden by cold working operations. These are manufactured by the standard fabrication process.
These fasteners exhibit good general and local corrosion resistance that is comparable to traditional grades. It is designed for utilization in chromium carbide precipitation in the temperature range between 427- 816 degree C.
These are hot formed in the temperature range between 2100- 2250 degree F recommended for other forming processes. The fasteners are water quenched and fully annealed after hot working to retain maximum corrosion resistance. This grade is quite ductile and forms easily.

To evaluate the quality of products we introduce product range with several tests. Those tests are the hardness test, tensile test, positive material test, micro/ macro test, destructive/non-destructive test, Wedge tensile strength, axial tensile test, proof load test, and fatigue test. Other tests are flexure test, compression test, torsion test, creep test, drop weight test, mechanical test, chemical analysis, intergranular corrosion test, flaring test, ultrasonic test, radiographic test, pitting corrosion test and third party inspection.
SS 347 / 347H Fasteners are packed in standard packing of the wooden box, crates, and cases to avoid damages while exporting.

What are the types of 347 stainless steel fasteners?

Fasteners are essential components in many industries, and great care must be taken when selecting them in order to avoid any catastrophic failures. When searching for reliable fasteners, 347 stainless steel is a popular option due to its excellent corrosion resistance even with exposure to highly corrosive environments. Types of 347 stainless steel fasteners available include flat head screws, hex lag screws, socket head cap screws, hex head cap screws, carriage bolts, and decking screws. These fasteners are ideal for applications where exposure to elevated temperatures up to 1600℉ is expected as the chromium-nickel alloy ensures high heat resistance. As its various forms can meet the needs of almost any project, it is no wonder that 347 stainless steel fasteners are commonly used in marine constructions and chemical plants where long-term performance is sought after.

What are the helpful properties of 347h ss fasteners?

347h SS fasteners are the perfect solution for applications that require a high degree of corrosion resistance and superior oxidation resistance. In such situations, their durability, strength, and performance characteristics make them an ideal choice. Not only do they stand up well against both oxidizing and reducing acids but also retain a good amount of their mechanical qualities even after long-term exposure to extreme temperatures ranging from cryogenic to those approaching 2000°F. They also have excellent stress rupture properties, leading to improved bolt joint integrity at prolonged elevated temperatures; plus, thanks to their low carbon content, 347h SS fasteners resist intergranular corrosion.
