There are many types of stainless steel. Here I will tell you about the classification of steel used in Stainless Steel Weld Tee. The details are as follows:

1. Austenitic stainless steel: The matrix is ​​mainly austenite (γ phase) with a face-centered cubic structure, non-magnetic, and mainly cold-worked to make it (and may cause magnetism);

2. Austenite-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 cold-worked to make it stainless steel ;

3. Ferritic stainless steel: The matrix is ​​mainly composed of ferrite (α phase) with a body-centered cubic crystal structure, which is magnetic and cannot be hardened by heat treatment, but can be finely processed by cold processing;

4. Martensitic stainless steel: The matrix is ​​martensitic, which is magnetic and can adjust its mechanical properties by heat treatment;

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

From the name of stainless steel tee, we can see that the material of stainless steel elbow must be stainless steel. The main difference between stainless steel elbow and carbon steel elbow is the material. The chemical composition contained in it will keep the surface of the elbow from rusting and corroding for a long time. The stainless steel elbow has a small diameter at both ends of the straight line and the end that is perpendicular to it is mainly used for the connection of small diameter branches. Elbows are divided into stainless steel elbows, forged steel elbows, carbon steel, alloy steel, etc. according to their materials. Elbow fittings can be divided into square edges and round edges.
