1.4571 stainless steel contains a small amount of titanium in its alloy composition. The titanium content is usually about 0.5%. Titanium atoms strengthen the 316 type structure at temperatures above 800 degrees Celsius. This helps to avoid carbide precipitation at grain boundaries and protect the material from corrosion. 1.4571, also known as 316Ti. It can be maintained at high temperatures for a period of time. Most of the mechanical properties of the 316 model remain the same in the 1.4571 level. Even in the 1920s, 1.4571 was used for a long time in the chemical processing industry. 316L is suitable for higher specification welding applications, while 1.4571 is suitable for wide applications in high-temperature environments. If 1.4571 is intentionally welded, it is recommended to use filler materials such as 1.4430,1.4776.
