Silver Tubes is a leading Exporter and dealer of Stainless Steel 347 Forged Fittings/ Stainless Steel 347H Forged Fittings, which is also advantageous for high temperature service because of its good mechanical properties. Forged Socket Weld Fittings are characterized by high chromium (19–32%) and molybdenum (up to 5%) and lower nickel contents than austenitic stainless steels. Forged Threaded Fittings have a varied microstructure of ferrite and austenite, where the purpose usually being to manufacture a 50/50 mix, though in marketable alloys the proportion may perhaps be 40/60. 347H Forged Socket Weld Fittings is also advantageous in applications that require omission of the annealing process after welding.
Forged Threaded Fittings are used for parts which are intermittently heated and cooled to temperatures between 800 degree F and 1600 degree F.The higher alloy content of SS 347 Forged Fittings makes them more expensive. 347H Forged Fitting offer similar performance at lower cost and are preferred in certain applications. Alloy 347 Forged Fittings can be used in applications requiring repeated heating in the range of 800 Degree F and 1650 Degree F (427 Degree C -899 Degree C). Alloy 347H Forged Fittings have a body-centered cubic crystal system and contain between 10.5% and 27% chromium with very little nickel, if any, but some types can contain lead.
