316 stainless steel properties and 316 stainless steel data sheet
316 stainless steel is a steel with better performance than 304, and the price is twice as expensive as 304.

316 stainless steel

Stainless steel is a type of steel, steel refers to the content of carbon (C) below 2%, called steel, and more than 2% is iron. The addition of chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo) and other alloying elements in the smelting process improves the performance of the steel and makes the steel corrosion-resistant (No rust) is the stainless steel we often say
316 stainless steel is an austenitic stainless steel material. Because of the addition of Mo, it has particularly good corrosion resistance, atmospheric corrosion resistance and high temperature strength. It can be used under harsh conditions, it has excellent work hardening (non-magnetic).

316 stainless steel properties

It is a low-carbon stainless steel with better welding performance than 304, and because stainless steel contains Mo, its pitting corrosion resistance in marine and chemical industrial environments is much better than 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good chloride corrosion properties. Among them, the 316 stainless steel variants include low-carbon stainless steel 316L, nitrogen-containing high-strength stainless steel 316N, and free-cutting stainless steel 316F with a higher amount of sulfur.
• preservative
316 stainless steel has good corrosion resistance. 304 stainless steel has good corrosion resistance in the pulp and paper production process. And 316 stainless steel is also resistant to the erosion of the ocean and corrosive industrial atmosphere. 316 stainless steel has almost become a standard material in the food and beverage industry. Due to the worldwide shortage of Mo and the higher Ni content in 316 stainless steel, the price of 316 stainless steel is more expensive than 304 stainless steel.
• Heat resistant
In intermittent use below 1600°C and continuous use below 1700°C, 316 stainless steel has good oxidation resistance. In the range of 800°C-1575°C, it is best not to continuously act on 316 stainless steel, but when 316 stainless steel is used continuously outside this temperature range, the stainless steel has good heat resistance. 316L stainless steel has better resistance to carbide precipitation than 316 stainless steel, and the above temperature range can be used.
Heat treatment
Annealing is carried out in the temperature range of 1850℃-2050℃, then rapid annealing, and then rapid cooling. 316 stainless steel cannot be hardened by heat treatment.
Welding
316 stainless steel has good welding performance. All standard welding methods can be used for welding. During welding, 316Cb, 316L or 309Cb stainless steel filler rods or welding rods can be used according to the application. In order to obtain the best corrosion resistance, the welded section of 316 stainless steel needs to be annealed after welding. If 316L stainless steel is used, post-weld annealing treatment is not required.


• Magnetic
Due to the wide application of austenitic stainless steel, it gives people the false impression that all stainless steels are not magnetic. For austenitic stainless steel, it can basically be understood as non-magnetic, which is true for quenched forged steel.

• Preservative
The corrosion resistance of 316 stainless steel pipe is better than that of 304 stainless steel pipe. Equipment made of 316 stainless steel pipe in the pulp and paper production process has better corrosion resistance. In addition, 316 stainless steel is also resistant to corrosion by the ocean and corrosive industrial atmosphere.
• Oxidation resistance
316 stainless steel pipe can be used intermittently below 871°C and continuous use above 927°C. In addition, 316 stainless steel pipe also has very good oxidation resistance. However, in the range of 427°C-857°C, do not use 316 stainless steel continuously, but when 316 stainless steel is used continuously outside this temperature range, it still has very good heat resistance. It should also be noted that the resistance of 316L stainless steel pipe to carbide precipitation is stronger than that of 316 stainless steel pipe, and the above-mentioned temperature range can be used. In addition, 316 stainless steel pipes cannot be hardened by heat treatment.
• Welding
In addition, the welding performance of 316 stainless steel pipe is very good, and it can be welded by almost all standard welding methods. When welding, according to the application, 316Cb, 316L or 309Cb stainless steel filler rods or welding rods can be used for welding. It should be noted that in order to obtain better corrosion resistance, the welded section of the 316 stainless steel pipe should be annealed after welding. If 316L stainless steel is used, post-weld annealing treatment is not required.
