304L stainless steel coils is a widely used low-carbon stainless steel material with strong anti-rust performance and excellent high temperature resistance. It can withstand high temperatures of 1000-1200℃. It has better corrosion resistance than 200 series stainless steel, especially when facing oxidizing acids. 304L stainless steel can also maintain good corrosion resistance in nitric acid environments with a concentration of no more than 65% and a temperature below the boiling point. At the same time, it also has good corrosion resistance to alkaline solutions and most organic and inorganic acids.
304L stainless steel has good corrosion resistance, heat resistance, low-temperature strength and mechanical properties. It is suitable for hot processing such as stamping and bending, and there is no heat treatment hardening phenomenon, and it remains non-magnetic. Its scope of application includes household items (such as tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs, etc.), automotive accessories (such as windshield wipers, mufflers, molded products), medical equipment, building materials, chemical industry, food industry, agriculture and ship parts, etc.

APPLICATION
THE DIFFERENCE BETWEEN 201 AND 304
The main difference between 201 and 304 stainless steel lies in composition and performance. 304 stainless steel is of better quality but more expensive, while 201 stainless steel is of slightly lower quality and relatively cheaper. The composition of 201 stainless steel includes 17% chromium, 4.5% nickel, and 6% manganese, while 304 stainless steel is composed of 18% chromium and 9% nickel. 201 has a brighter surface, a dark luster, and is magnetic due to its higher manganese content, and is often used in railway vehicles and other fields. In contrast, 304 stainless steel has better corrosion resistance and is often used in food production equipment, chemical equipment, and nuclear energy.
201 stainless steel has poor corrosion resistance and is easy to rust, so the price is low. 304 stainless steel has a higher chromium content, a matte surface and is not easy to rust, so it is widely used. Due to the lower nickel content of 201, the price is relatively cheap, but its corrosion resistance is far less than that of 304.
The reason why stainless steel is not easy to rust is that chromium-rich oxides will form on its surface to protect the steel body. 201 is a high manganese stainless steel with high hardness, low carbon and nickel content, poor toughness and poor fatigue resistance compared to 304. Due to its higher nickel content and better corrosion resistance, 304 stainless steel can better resist oxidation and rust during use.
In terms of composition comparison, the carbon content of 304 stainless steel does not exceed 0.08%, the silicon content does not exceed 1.00%, the manganese content is below 2.00%, the chromium content is 18-20%, and the nickel content is 8-10%; while the carbon content of 201 stainless steel is higher, up to 0.15%, the silicon content does not exceed 1.00%, the manganese content is between 5.5-7.5%, the chromium content is 16-18%, and the nickel content is 3.5-5.5%.
THE DIFFERENCE BETWEEN 316 AND 304
316 and 304 stainless steel are the two most commonly used stainless steel materials. The main difference between them is that 316 contains molybdenum (Mo). This composition makes 316 better than 304 in corrosion resistance, especially in high temperature environments, 316 is more corrosion resistant, so engineers usually choose 316 as a component material under high temperature conditions. However, although 316 has excellent high temperature resistance, even 316 is not suitable for use in concentrated sulfuric acid environments because molybdenum and sulfur ions in sulfuric acid may react and cause corrosion.
Molybdenum (Mo) is a high temperature resistant material and is often used in high temperature applications. For example, molybdenum crucibles are used to melt gold, which also proves the high temperature tolerance of molybdenum. However, it should be noted that molybdenum is also easy to react with high-valent sulfur ions to form sulfides, so no stainless steel can be absolutely corrosion-resistant in all environments. Stainless steel is essentially an alloy material. Although it contains different elements to improve corrosion resistance, it may still react with certain substances.
