Таркиб ва хосиятҳои аз пӯлоди зангногир 316L

Have you ever wondered why seemingly ordinary stainless steel products can last for a long time in various harsh environments? The answer lies in their composition and properties. Today, let’s take a look into the world of 316L пӯлоди зангногир and explore the mysterious composition and amazing хосиятҳои аз пӯлоди зангногир 316L.

What is the chemical composition of 316L stainless steel?

The chemical composition of 316L stainless steel is as follows:

1. Хром (Cr): 16.0% - 18.0%
2. Никел (Ni): 10.0% - 14.0%
3. Molybdenum (Mo): 2.0% – 3.0%
4. Manganese (Mn): maximum 2.00%
5. Silicon (Si): maximum 1.00%
6. Phosphorus (P): maximum 0.045%
7. Sulfur (S): maximum 0.030%
8. Carbon (C): maximum 0.03%

Among them, chromium is one of the most important alloying elements in 316L stainless steel, which gives it excellent corrosion resistance. Nickel can improve the strength and toughness of stainless steel, while molybdenum can further enhance its corrosion resistance and heat resistance. At the same time, a low carbon content design can reduce the risk of intergranular corrosion in the welding process of 316L stainless steel.

3. Thermal expansion coefficient: 16.5 × 10^-6 /℃ (20 – 100 ℃)
4. Қобилияти гармидиҳӣ: 16.3 Вт/(м·К) (100℃)
5. Specific heat capacity: 500 J/(kg·K) (20℃)

Бояд гуфт, ки чисмонй хосиятҳои аз пӯлоди зангногир 316L are also affected by many factors, such as temperature, pressure, and material state. Therefore, in specific application scenarios, the physical properties of 316L stainless steel need to be evaluated based on the actual situation.

Is 316L stainless steel food grade?

316L stainless steel is often considered a food-grade material because it complies with many international standards and regulations, such as the requirements of the FDA (U.S. Food and Drug Administration) and the European health and safety standard EN 10088. This means that 316L stainless steel can be used to manufacture equipment and containers that come into contact with food, such as pipes, tanks, and barrels used to process, store, and transport food.

It should be noted that even food-grade 316L stainless steel requires strict control of its surface quality and cleanliness during manufacturing, use, and maintenance, and avoidance of contact with other substances that may contaminate food, to ensure food safety and hygiene.

Characteristics of 316L Stainless Steel

The main characteristics of 316L stainless steel are as follows:

1. Муқовимати аъло ба зангзанӣ: 316L stainless steel has good corrosion resistance, especially in strong corrosive media such as chlorides. Therefore, it is widely used in the manufacture of components used in corrosive environments such as seawater treatment equipment, chemical pipelines, and oil and gas pipelines.
2. Low carbon content: The low carbon content of 316L stainless steel can reduce the risk of intergranular corrosion and other metallurgical defects, and also better control its quality and performance during welding.
3. Коркарди хуб: 316L stainless steel is easy to cut, shape, and weld, meeting different processing and manufacturing requirements.
4. Қувват ва устувории баланд: After proper cold working and heat treatment, 316L stainless steel can achieve high strength and toughness, making it suitable for applications with high mechanical loads.
5. Майдонҳои васеи барнома: 316L stainless steel is widely used in medical devices, food processing, chemicals, marine engineering, marine engineering, construction and other fields.
