Ninthore Overseas is one of the Leading Manufacturer And Exporter Of High Quality Stainless Steel 304L Pipe Fittings, which is a precipitation – harden able nickel – copper alloy that combines high strength, corrosion resistance and non – magnetic properties. There is no need for post weld heat treatment in these Stainless Steel 304L Compression Pipe Fittings, however, thorough cleaning after welding is critical for optimum corrosion resistance, otherwise there is the risk of contamination and embrittlement. Like most other nickel alloys, our Stainless Steel 304L Ferrule Pipe Fittings is typically tough to machine and will work harden.

These Stainless Steel 304L Double Ferrule Pipe Fittings has excellent results which can be obtained if you make the correct choices for tooling and machining. Our Stainless Steel 304L Accessories is a solid – solution binary alloy, which will exhibit only randomly dispersed non – metallic inclusions. As nickel and copper are mutually soluble in all proportions, these SS 304L Compression Pipe Fittings is a single – phase alloy and consist of metal sulphide or silicates.

Stainless Steel 304L Pipe Fittings

Tests exposed in boiling acid for our SS 304L Ferrule Fittings exhibit general corrosion rates of 30 mpy (0.8 mm / a) in 20 % acid and greater than 100 mpy (2.5 mm / a) at higher concentrations. These SS 304L Double Ferrule Fittings can be readily joined and fabricated, which further has excellent mechanical properties at sub – zero temperatures.
