Stainless Steel 347 Fasteners

SS 347 U Bolt, UNS S34700 Hex Nut, UNS S34700 Bolt, ASTM A193 SS 347 Fasteners, Werkstoff Nr. 1.4550 Stud Bolt, ASME SA193 SS 347 Threaded Rod, Werkstoff Nr. 1.4550 Allen Bolt, Din 1.4550 Nut, Stainless Steel 347 Hex Bolt.

The excellent resistance of the Stainless Steel 347 Fasteners to intergranular corrosion during chromium precipitation at temperatures from 427 degrees celsius to 816 degrees celsius was one of the factors that led to particular invention of this grade. Chromium carbide production is prevented because titanium is included in the alloy.

In addition to being resistant to intergranular corrosion, UNS S34700 Hex Nut are an excellent choice for high-temperature applications. It is because fasteners retain beneficial mechanical properties, such as high creep and tensile strength, even when subjected to elevated temperatures.

About Stainless Steel 347 Fasteners

SS 347 Hex Bolt Stockist, Werkstoff Nr. 1.4550 Allen Bolt Supplier, Din 1.4550 Nut Manufacturer, ASME SA193 SS 347 Threaded Rod Stockist, ASTM A193 Stainless Steel 347 Fasteners Manufacturer, Din 1.4550 Stud Bolt Exporter.

In general and localized corrosion, the corrosion resistance of ss 347 bolts and 304 is comparable. Although prolonged heating of grade 347 in the chromium precipitation range has the potential to affect the general resistance of the alloy in various media, it is essential to note that this is not always the case. When exposed to conditions containing halide compounds, Grade 347 Stud Bolts are just as prone to stress-related corrosion cracking as other stainless steel.

In the presence of chloride ions, alloy stainless steel 347 nuts have resistance comparable to fasteners of grade 304 or type 304l. Both stabilized alloys, such as Din 1.4550 Threaded Rod and sterilized alloys, are considered to have a limit of 100 ppm chloride in aqueous environments when used in applications that contain crevices. Chloride ion levels above 100 ppm can cause crevice corrosion and pit, the same as parts per million. When dealing with applications with high chloride content levels, it is best to consider using a stainless steel grade such as 316 or a stainless steel grade with a high molybdenum concentration.
