Stainless steel is a common steel material, so what are the advantages and disadvantages of stainless steel?
Advantage:
1. Physical properties: Stainless steel has heat resistance, high temperature resistance, low temperature resistance and even ultra-low temperature resistance.
2. Chemical properties: The chemical and electrochemical corrosion resistance of stainless steel is very good in steel, second only to titanium alloy.
3. Process performance: Austenitic stainless steel has the best process performance. Because of its good plasticity, it can be processed into various plates, tubes and other profiles. It is suitable for pressure processing. Martensitic stainless steel has poor process performance due to its high hardness.
4. Mechanical properties: According to different types of stainless steel, the mechanical properties are different. Martensitic stainless steel has high strength and hardness, and is suitable for manufacturing corrosion-resistant parts that require high strength and high wear resistance, such as turbine shafts, stainless steel knives, stainless steel bearings, etc. Austenitic stainless steel has good plasticity, not too high strength, but the best corrosion resistance among stainless steels. It is suitable for occasions that require very corrosion resistance but do not require high mechanical properties, such as chemical plants, fertilizer plants, sulfuric acid, and hydrochloric acid manufacturers and so on.
Disadvantages:
The disadvantages of stainless steel are obvious, high cost, and more expensive. In addition, stainless steel is not resistant to corrosion by alkaline media. Long-term use or improper maintenance will cause serious damage to stainless steel.
