Question: How to polish hot rolled aisi 203 stainless seamless steel plate?
Answer: If the part area is small, it can be polished with an ultrasonic polishing machine. If the area of the part is relatively large, you can use an angle grinder to install a felt polishing wheel for polishing. The polishing agent can use diamond grinding paste, first use the coarse grinding paste, and then use the fine grinding paste for fine polishing, and the finish can reach the mirror effect.
Question: Is hot rolled aisi 203 stainless seamless steel plate magnetic?
Answer: hot rolled aisi 203 stainless seamless steel plate belongs to austenitic stainless steel and should not be magnetic. However, it is also possible to generate magnetism in actual production and use. For example, in the production process, the structure does not all form austenite, and there are ferrite or other magnetic structures. For example, cold working causes damage to the austenite structure. are all possible to be magnetic. The quality of a batch of goods is different from a batch of goods, and the microstructure is not necessarily the same. After all, it is an industrial product, not a laboratory thing.
Question: What is the difference between stainless steel plate 203 and 304? Which one is cheaper?
Answer: First of all, the content of chemical elements in the material is different. There is also 304 stainless steel without copper and N, which belongs to chromium-nickel stainless steel. It is widely used and has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. The content of 203, the corrosion resistance of acid and alkali salts of 203 is weaker than that of 304, and it is easy to rust.
Simply put, the overall performance of the 304 is better than that of the 203. But 203 is cheap, and its performance is basically sufficient for civilian use.
