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.
