Generally, we can't see the difference between 304 stainless steel pipes and 316 stainless steel pipes, and a national third-party professional inspection report is required. What is the difference between 304 stainless steel pipe and 316 stainless steel pipe?

1. Element composition:
304 stainless steel pipes contain an average of 9% nickel; 316 stainless steel pipes contain an average of 12% nickel. Nickel plays a role in improving high temperature resistance, mechanical properties, and oxidation resistance in metal materials. Therefore, the amount of nickel contained in the stainless steel pipe directly affects the overall performance of the pipe.

2. Pipeline performance:

304 stainless steel pipe has a variety of superior mechanical properties, has considerable corrosion resistance, high temperature resistance, and is the most widely used stainless steel pipe.

316 stainless steel tube is following the application of 304 stainless steel tube, the main characteristic is the resistance to acid and alkali, high temperature resistance than 304 stainless steel tube, mainly used in the food industry and surgical instruments and other precision instruments are more.

3.Corrosion resistance：

316 stainless steel tube is 304 stainless steel tube in the corrosion resistance of the stainless steel tube produced by adding some more molybdenum elements. If it is in distilled water, drinking water, boiler water, river water medium, 304 stainless steel tube and 316 stainless steel tube corrosion resistance is almost as strong, but if it is in the very high chloride ion content of the media environment, 316 stainless steel tube will be more suitable.

4.Price：

Because 316 stainless steel pipes add more molybdenum and nickel elements, the price of 316 stainless steel pipes is higher than that of 304 stainless steel pipes.

All stainless steel pipes have their specific functions and scope of use, and rational use of their advantages and disadvantages will create greater value for us.
