Sachiya Steel International is one of the leading manufacturer and exporter of Stainless Steel 446 Tube to Male Fittings, which is available in different specifications as per clients’ requirements. The microstructure of Stainless Steel 446 Tube Fittings consists of about 50 % of the hard intermetallic Laves phase dispersed in a softer cobalt alloy matrix. Stainless Steel 446 Compression Fittings provides the material with exceptional metal to metal wear bearing properties, where follow annealing by stabilization and aging treatments. The high levels of molybdenum and chromium present in Stainless Steel 446 Male Connector Fittings favors the formation of the high hardness phase and also provide a high level of corrosion resistance.
The phase of Stainless Steel 446 Ferrule Fittings itself has a 2840 Degree F melting point, which helps to retain its wear resistance to high temperatures. Mechanical properties of Stainless Steel 446 Double Ferrule Fittings vary with the solution and aging treatments, where shapes are available per customer requirements. Higher solution temperatures of 446 Stainless Steel Male Connector Fittings result in better room temperature ductility and elevated temperature creep – rupture strength.
Lower solution temperatures in 446 Stainless Steel Tube Fittings give higher tensile strengths, where short time hot tensile strength is inferior at temperatures up to 1350 Degree F. The creep – rupture strength of 446 Stainless Steel Compression Fittings is superior to that of alloy 718 at temperatures above 1150 Degree F – 1200 Degree F.
