Silver Tubes is a leading Exporter and manufacturer of Stainless Steel 347 Pipe Fittings /Stainless Steel 347H Pipe Fittings, which have a mixed microstructure of austenite and ferrite. Meanwhile, the aim of Stainless Steel 347 Butt Weld Fittings is usually being to produce a 50/50 mix, although in commercial alloys the ratio may be 40/60. Stainless Steel 347 Butt Weld Pipe Fittings are characterized by high chromium (19–32%) and molybdenum (up to 5%) and lower nickel contents than austenitic alloys. Stainless Steel 347H Butt Weld Pipe Fittings is also advantageous for high temperature service because of its good mechanical properties. Stainless Steel 347H Butt Weld Fittings is also advantageous in applications that require omission of the annealing process after welding.
SS 347Pipe Fittings are used for parts which are intermittently heated and cooled to temperatures between 800 degree f and 1600 degree f. SS 347H Pipe Fittings can be used in applications requiring repeated heating in the range of 427 Degree C -899 Degree C.The higher alloy content of Alloy 347 Pipe Fittings makes them more expensive. Alloy 347H Pipe Fittings can offer similar performance at lower cost and are preferred in certain applications. A typical composition of 18% chromium and 10% nickel in 347 Stainless Steel Pipe Fittings, commonly known as 18/10 stainless, is often used in cutlery and high-quality cookware.
