347 Stainless Steel Pipe Description

347 stainless steel pipe is generally more durable than other stainless steel materials under high temperatures. This makes it an ideal option for high temperature environments. 347 stainless steel pipe maintains its strength and durability without embrittlement or fatigue In high-temperature settings. 347 stainless steel pipe also has excellent corrosion resistance. Its ability to remain stable in corrosive environments with strong acids and bases such as chloride ions and sulfide ions explains why it is commonly used in the chemical and petroleum industries. In addition, 347 stainless steel also has good processing properties. It can be processed into various shapes through forging, quenching, annealing and cold working. Overall speaking, 347 stainless steel pipe is popular in industries such as chemical, petroleum, pharmaceutical and food processing for its high temperature durability, corrosion resistance and processability.
