What Are The Commonly Used Steel Materials For Thick Stainless Steel Pipe Fittings

Stainless Steel Weld Fitting is mainly used for the connection of buried water supply and gas transmission pipelines. It can tightly connect the pipe ports, has good quality and reasonable price. It has strong toughness and can stretch the pipe to 5 times the original length without breaking. It is suitable for uneven geological conditions without affecting its connection performance.

What are the commonly used steel materials for thick stainless steel pipe fittings:

1. Martensitic stainless steel: The matrix is ​​martensitic, magnetic, and its mechanical properties can be adjusted by heat treatment;

2. Precipitation hardening stainless steel: The matrix is ​​austenitic or martensitic, and can be hardened (strengthened) by precipitation hardening (also known as aging hardening);

3. Austenitic stainless steel: The matrix is ​​mainly austenitic (γ phase) with a face-centered cubic structure, non-magnetic, and mainly strengthened (and possibly magnetized) by cold working;

4. Austenitic-ferrite (duplex) stainless steel: The matrix has both austenite and ferrite phases (the content of the lesser phase is generally greater than 15%), is magnetic, and can be strengthened by cold working;

5. Ferritic stainless steel: The matrix is ​​mainly ferrite (α phase) with a body-centered cubic crystal structure, is magnetic, and generally cannot be hardened by heat treatment, but can be slightly strengthened by cold working.
