Stainless Steel 347H Nipple

These Stainless Steel 347H One End Threaded Nipple is highly resistant to a wide range of acids and bases, both organic and inorganic, which makes it an interesting and exceptional long – life alternative to other materials in highly demanding applications. Our SS 347H Both End Threaded Nipple has very high resistance to chloride corrosion, combined with very high mechanical strength. Many elements and compounds that are not normally classified as alloys under high pressures, these Stainless Steel 347H Concentric Swaged Nipple are formed as metallic allotropes of non – metals.

The strength and resilience of our Stainless Steel 347H Eccentric Swaged Nipple has led to their frequent use in high – rise building and bridge construction, as well as most vehicles, many home appliances, tools, pipes, non – illuminated signs and railroad tracks. Painting, anodizing or plating are good ways to prevent corrosion of these 347H Stainless Steel Nipple.
