Overview
204 stainless steel is a kind of austenitic stainless steel, belonging to the 200 series. Austenitic steels are known for their excellent corrosion resistance and high ductility, making them ideal for a wide range of applications. 204 stainless steel is different from similar products in that it contains less nickel than similar products.
In fact, it contains only about 3.5% nickel compared to the typical 8-10% found in most austenitic steels. This leads to lower-cost alternatives without sacrificing quality and durability. Despite the low nickel content, 204 stainless steel has good corrosion resistance and can be used in applications where it may come into contact with moisture or corrosive substances. It also has good toughness and weldability, making it easy to use in the manufacturing process.

204 pipe field of use
204 Stainless steel is mainly used in the manufacture of household appliances, auto parts, building materials, machinery manufacturing and other fields of parts and equipment.
Advantages
204 stainless steel is a high quality alloy with many advantages. One of the greatest advantages of this stainless steel is its excellent corrosion resistance. It can withstand harsh environments and exposure to chemicals, making it ideal for applications in the chemical, food processing and medical industries.
Another benefit of 204 stainless steel compared to other stainless steel alloys is that it is affordable. Its low nickel content reduces costs without compromising performance or quality. This makes it an attractive option for manufacturers looking for cost-effective solutions without sacrificing durability.
204 stainless steel in addition to affordable and corrosion resistance, but also has good formability and weldability. This means that it can be easily molded into a variety of products or components while maintaining its strength and integrity.
In addition, 204 stainless steel has excellent heat resistance, making it ideal for high temperature applications such as furnaces or ovens. Its ability to resist oxidation at high temperatures ensures longevity in these demanding conditions.
Overall, 204 stainless steel has a range of advantages, including excellent corrosion resistance, economy, good formability and weldability, and excellent heat resistance, making it suitable for a variety of industrial applications where durability is most important.
Disadvantage
A major disadvantage of 204 stainless steel is its limited corrosion resistance. This means it may not work properly in environments with high humidity or exposure to corrosive substances.
Another disadvantage is its lower strength and hardness compared to other grades such as 304 or 316. This makes it less suitable for applications where durability and toughness are key factors.
In addition, the weldability of 204 stainless steel can be more challenging than other grades because its higher carbon content can cause cracking during welding. While 204 stainless steel is more affordable than some advanced materials, it may not always offer the best value over time due to its limitations in certain areas, including corrosion resistance and overall durability.
