Ninthore Overseas is one of the leading Manufacturer And Exporter Of High Quality SMO 254 Pipe Fittings, which gives better guaranteed corrosion resistance. These SMO 254 Compression Pipe Fittings resists chloride environments and sulphide stress corrosion. SMO 254 Compression Fittings is also roughly double the strength of standard austenitic stainless steels. We recommend a maximum hot forming temperature of these SMO 254 Ferrule Pipe Fittings between the range of 2010 Degree F and 2100 Degree F (1100 Degree to 1150 Degree C). If the shape of the work piece is not compact, the edges of SMO 254 Double Ferrule Pipe Fittings may be significantly cooler than the bulk, and there is risk of cracking in the cooler regions.

These SMO 254 Accessories are somewhat more difficult to machine than the 300 series austenitic stainless steels. Higher cutting forces in Alloy 254 Compression Pipe Fittings are required and more rapid tool wear is typical, where the high strength can pose problems. These Alloy 254 Ferrule Pipe Fittings is not generally suitable for use at temperatures above 300 Degree C as it suffers from precipitation neither of brittle micro constituents, nor below -50 Degree C because of its ductile – to – brittle – transition.
