Stainless steel seamless elbows and straight seam elbows are relative. In order to better distinguish the two, relevant introductions will be made below.
The stainless steel seamless elbow material is 20#, and the straight seam elbow is Q235.
From the appearance analysis, the seamless elbow is formed by hot punching of round steel, and the straight seam elbow is made by welding and rolling steel plates. Due to different processing methods, the appearance of the two is also different, and the straight seam elbow is relatively better.
From the material analysis, there are differences in the material essence, material density, material element content and weldability of seamless elbows and straight seam elbows. Seamless elbows are relatively better.
