There are many types of stainless steel. Here I will tell you about the classification of steel used in stainless steel pipe elbows and tees. The details are as follows:
1. Austenitic stainless steel: The matrix is mainly austenite structure (γ phase) with a face-centered cubic structure, non-magnetic, and is mainly cold-worked (and may cause magnetism) stainless steel;
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 Stainless steel that can be hardened by cold working;
3. Ferritic stainless steel: The matrix is mainly ferrite (α phase) with body-centered cubic crystal structure, which is magnetic and cannot be hardened by heat treatment, but cold working can make it fine stainless steel;
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).
Stainless steel tee From its name, we can see that the material of the stainless steel elbow must be stainless steel. The main difference between stainless steel elbow and carbon steel elbow is the material. The chemical composition it contains 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 a vertical bifurcation end, which 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.
