Stainless Steel 347 Circle & Rings Characteristics
Due to existing elements, these circles and rings have great features, making them more applicable to engineering-related industries. It has increased flexibility for higher power applications and temperatures (more than 1000 ° F).The Stainless Steel 347 alloy-made circles and rings can be used in nitric solutions, most diluted organic acids at average temperatures. In comparison, it’s also applicable in pure phosphoric acid at lower temperatures.
SS 347 rings can resist polythionic acid stress corrosion cracking in hydrocarbon service uses; thus, they are used in fluoride-free caustic solutions at modest temperatures.Alloy 347 deals with Chromium Carbide, which has superior resistance against the inter-corrosive environment. It works stably in addition to columbium and tantalum alloys, its main feature.
These circles and rings enhance creep resistance and higher thermal stability even in high-temperature surroundings. It possesses excellent resistance to erosion, abrasion, and sulfidation corrosion.
What is the composition of the Stainless steel 347H Circle?
The Chemical Composition of 347H stainless steel circle consists of the following:
• Phosphorus (0.045%)
• Silicon (0.75%)
• Chromium (17.00 min. to 19.00 max%)
• Manganese (2.00%)
• Carbon (0.04 min. to 0.10 max.%)
• Nickel (9.00 min.%)
Tantalum and columbium are other prime elements in good percentages in the chemical composition.
It is a version of stainless steel alloy 347H, also referred to as the UNS S3409, with a high carbon percentage.
