321 SS (UNS S32100) is a titanium stabilized austenitic stainless steel that features improved resistance to intergranular corrosion. This grade is suitable for high-temperature applications up to 1500°F (815°C), where the addition of titanium stabilizes the material against chromium carbide formation.
What is alloy 20 made of?
Description. Alloy 20 is a nickel-iron-chromium based, austenitic alloy with excellent corrosion resistance in chemical environments containing sulfuric acid and many other aggressive media. This alloy is stabilized with niobium to resist intergranular corrosion.
What is SS347?
Home » Stainless Steel / Austenitic Stainless Steel. Similar to SS321, stainless steel 347(SS347) is an austenitic stainless steel with deliberate addition of tantalum(Ta) and niobium(Nb) to the basic stainless steel 304(SS304).
What is the difference between 316 and 321 stainless steel?
The most popular acid-resistant material is steel AISI 316, which exhibits increased resistance to corrosion in very aggressive chemical environments. The third tested type is AISI 321, which shows high resistance to inter-crystalline corrosion and resistance to the work in higher temperatures, i.e. 400 – 800°C [9].
What is C alloy?
Alloy C. Page 1. Wilfley’s Alloy C is a nickel base alloy that contains significant amounts of molybdenum and chromium. Alloy C has exceptional resistance to strong oxidizing and reducing agents. Classification and Mechanical Properties.
What is another name for Alloy 20?
Carpenter 20
Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid.
What is the difference between 321 and 347 stainless steel?
Alloy 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100). Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 – 0.10) version of the alloy.
What is SUS in stainless steel?
Stainless steel is the alloy of chromium and nickel. Sometimes, it is referred as SUS, an acronym from Japanese Industrial Standards (JIS). Stainless steel has various types to meet various needs, and is used in numerous precision machine parts, bolts, and nuts.
What does 347h mean on stainless steel?
AISI 347H stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 347H is the AISI designation for this material. S34709 is the UNS number.
What is the creep resistance of 347h alloy?
The alloy has good oxidation resistance and creep strength to 1500°F (816°C). It also possesses good low temperature toughness. Alloy 347H (UNS S3409) is the higher carbon (0.04 – 0.10) version of the alloy. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000°F (537°C).
What are the properties of alloys 347?
General Properties. Alloy 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100).
How do you heat treat grade 347h stainless steel?
Grade 347H stainless steel can be readily stamped, blanked, spun and drawn as it is quite tough and ductile. Grade 347H stainless steel can be annealed at temperature ranging from 1010 to 1193°C (1850 to 2000°F) and then quenched with water. Grade 347H stainless steel is unresponsive to heat treatment.
