321 Stainless Steel Pipe
What is 321 stainless steel?
321 stainless steel is a type of austenitic stainless steel that contains titanium, which provides improved high-temperature strength and resistance to intergranular corrosion.
What are the advantages of using 321 stainless steel pipes?
321 stainless steel pipes have excellent high-temperature strength, oxidation resistance, and good mechanical properties.
What are the applications of 321 stainless steel pipes?
321 stainless steel pipes are widely used in industries such as chemical, petrochemical, power generation, and furnace manufacturing.
What is the difference between 304 and 321 stainless steel pipes?
321 stainless steel pipes contain titanium, which provides improved high-temperature strength and resistance to intergranular corrosion, while 304 stainless steel pipes do not.
What is the maximum temperature that 321 stainless steel pipes can withstand?
321 stainless steel pipes can withstand temperatures up to 1500°F (816°C).
What is the minimum temperature that 321 stainless steel pipes can withstand?
321 stainless steel pipes can withstand temperatures as low as -450°F (-268°C).
What is the maximum pressure that 321 stainless steel pipes can withstand?
The maximum pressure that 321 stainless steel pipes can withstand depends on the size, wall thickness, and temperature of the pipes. Generally, they can withstand pressures up to 1000 psi.
What is the minimum pressure that 321 stainless steel pipes can withstand?
321 stainless steel pipes can withstand very low pressures, such as those found in vacuum systems.
What are the different finishes available for 321 stainless steel pipes?
The different finishes available for 321 stainless steel pipes include brushed, mirror, satin, and matte.
What are the different grades of 321 stainless steel pipes?
There are several grades of 321 stainless steel pipes, including 321H, which has higher carbon content for improved high-temperature strength.
What are the different standards for 321 stainless steel pipes?
The different standards for 321 stainless steel pipes include ASTM A312, ASTM A269, and ASTM A213, which specify the requirements for the manufacturing, testing, and quality control of the pipes.
What is the weight of 321 stainless steel pipes?
The weight of 321 stainless steel pipes depends on the size, wall thickness, and length of the pipes. A 1-inch diameter pipe with a wall thickness of 0.065 inches and a length of 10 feet weighs approximately 3.4 pounds.
What is the density of 321 stainless steel pipes?
The density of 321 stainless steel is approximately 7.9 g/cm³.
