430 316L Custom 2.5 stainless steel exhaust pipe

In fact, this product of ours is definitely used in many home appliances and has a very good heat exchange effect. But do you know how to deal with this type of product if the surface is not very shiny? Here we I also gave you a brief introduction, if you are interested, you can take a look.


1. Raw material issues.

(1) Good raw materials can produce good products, while inferior raw materials can produce products with slightly inferior quality. Good steel strips have stable element content, and the produced 430 316L Custom 2.5 stainless steel exhaust pipe has a high gloss;

As for inferior pipes, the element content of the stainless steel heat exchange tubes produced is unstable, so the gloss of the stainless steel heat exchange tubes will be very dark.

(2) Material of raw materials. Common stainless steel heat exchange tubes are made of 0Cr18Ni9 (304) stainless steel and 00Cr19Ni10 (304L) stainless steel, two widely used austenitic stainless steels.

If the hardness is too low, it will not be easy to polish during polishing, and if the hardness is too low, orange peel phenomenon will easily appear on the surface during deep drawing, thus affecting the gloss. Stainless steel with high hardness will have good polishing effect and relatively low gloss. good.

In addition, the thickness of stainless steel pipes is between 0.52-1.1 mm, and the polishing effect is good, because the polishing intensity of thinner and thicker ones is more difficult to control. If the intensity is high, the thin tube will be deformed, and if the intensity is small, the polishing intensity of the thick tube cannot be achieved.

(3) Surface defects of raw materials, such as scratches, pitting, scratches, blisters, etc. The occurrence of these defects will directly affect the production process of stainless steel heat exchangers, thereby making the glossiness of the produced stainless steel heat exchanger tubes low. .


2. Manufacturing process.

The polishing process during the production process has a direct impact on the glossiness of the 430 316L Custom 2.5 stainless steel exhaust pipe. That is to say, if the stainless steel heat exchange pipe is polished, due to external factors (temperature, humidity) and other factors The impact of the stainless steel heat exchange pipe caused problems in the polishing process. The result was that the glossiness of the produced 430 316L Custom 2.5 stainless steel exhaust pipe was not high and the surface was dull.
