What is the difference between 304 stainless steel plate and 316 stainless steel plate?

What is the difference between 304 stainless steel plate and 316 stainless steel plate?

What is the difference between 304 stainless steel plate and 316 stainless steel plate? The following is introduced by China Wuxi JiaNuo special steel stainless steel to give you the following. Two commonly used stainless steel 304, 316 (or 1.4308 and 1.4408 corresponding to German/European standards), 316 and 304 in the chemical composition of the main difference is that 316 contains molybdenum, and it is generally believed that 316 has better corrosion resistance than 304 in high temperature environments. Therefore, in high-temperature environments, engineers generally choose 316 parts. But the so-called thing is not relative. In a concentrated sulfuric acid environment, do not use 316 at any higher temperature.

1, 304 stainless steel sheet is a commonly used material in stainless steel, with a density of 7.93g/cm3, also known as 18/8 stainless steel in the industry. Resistant to high temperatures of 800 degrees, with good processing properties and high toughness characteristics, widely used in production, furniture decoration and food medical industry.

2, 316 stainless steel sheet is a general-purpose steel with excellent corrosion resistance. Its thermal conductivity is better than austenite, the coefficient of thermal expansion is smaller than austenite, poor heat resistance, the addition of stabilizing elements titanium, the mechanical properties of the weld seam is good. 430 stainless steel is suitable for architectural decoration, fuel burner parts, household appliances, household appliances, etc.

304 stainless steel is a general-purpose stainless steel material. The surface resistance to high temperature is also better. In general, the temperature limit is lower than 650 ℃. 304 stainless steel has high quality stainless steel corrosion resistance and good intergranular corrosion. 316 stainless steel, 18cr-12 ni-2.5mo, due to the increase of Mo, its corrosion resistance, resistance to high momentum corrosion and high temperature strength is particularly good, can be used in harsh conditions; excellent work hardening properties.

1, the use of different: 304 stainless steel is mainly used for corrosion-resistant containers, tableware, furniture, railings and medical equipment. 316 stainless steel is mainly used in the food industry, watch accessories, pharmaceutical industry and surgical equipment.

2, different chloride corrosion resistance: 304 stainless steel for non-magnetic materials, heat treatment will not change its metallurgical organization. 316 stainless steel due to the addition of molybdenum and has a special corrosion-resistant structure, with stronger resistance to chloride corrosion. It is also used as “marine steel”.

In summary, by reading the above, friends can understand the difference between 304 stainless steel and 316 stainless steel. It is not easy to see when identifying. If conditions allow, stainless steel drugs can be used to identify, mainly to see which of the two has a stronger anti-corrosion ability. Friends can choose as needed when they choose.
