High Quality SMO 254 Unions Worldwide

Renaissance Fittings and Piping Inc. offers a wide array of 254 SMO Tube to Union Fittings similar to parker and swagelok, where we offer them in varied standard sizes and thickness and ensure long functional life. These SMO 254 Tube Fittings (UNS S31254) offers chloride resistance superior to that of Alloy 904L, Alloy 20, Alloy 825 and Alloy G. Our SMO 254 Compression Fittings is a high alloyed austenitic stainless steel with exceptional corrosion resistance. These SMO 254 Ferrule Fittings is substantially stronger than the common austenitic grades, with strength nearly twice that of 300 series stainless steel. Our SMO 254 Double Ferrule Fittings may offer a cost effective solution to Nickel and Titanium alloys in several environments. Meanwhile, these SMO 254 Union Tube Fittings are also being offered in different sizes and shapes to our customers. Because of the similarities among the 6Mo grades, our Alloy 254 Union Fittings may be used interchangeably, may be used together and the selection of a specific grade should be based on availability, price, and service. These Alloy 254 Tube Fittings has a good weldability and the methods used for welding conventional austenitic steels are used. Our Alloy 254 Compression Fittings is more sensitive to some extent in relation to hot cracking and shall be welded with low heat input. Filler metal of these Alloy 254 Ferrule Fittings is recommended, where these filler metals will give a weld with a resistance to pitting corrosion.
