Product Description

347 stainless steel is made of a high-temperature oxidation-resistant stainless steel material mainly consisting of chromium, nickel and titanium. It can be used at high temperatures and resists corrosion and oxidation effectively. 347 stainless steel is more durable than other stainless steel materials under high temperatures . This makes it very popular for use in high temperature environments. 347 stainless steel maintains its strength and durability without embrittlement or fatigue i n high-temperature yet corrosive environments. Its ability to remain stable in corrosive environments with strong acids and bases such as chloride ions and sulfide ions makes it ideal for use in the chemical and petroleum industries. In addition, 347 stainless steel also has good processing properties. That is why the bars can be processed into various shapes by various methods such as forging, quenching, annealing and cold working. They are commonly seen as manufacturing parts in industries such as chemical, petroleum, pharmaceutical and food processing due to high temperature durability, corrosion resistance and processability.
