Grade Overview

Overview of 347 / 347H Stainless Steel Sheets

347 and 347H stainless steel sheets are niobium-stabilized austenitic stainless steels developed for high-temperature applications. The addition of niobium enhances resistance to intergranular corrosion by preventing chromium carbide precipitation during welding or prolonged exposure to elevated temperatures. The "H" grade (347H) contains a higher carbon content, providing improved creep strength and better performance in high-temperature pressure systems.

Composition Analysis

Metallurgical Characteristics of SS 347/347H Sheet

The specific combination of elements in 347/347H ensures optimized high-temperature performance and intergranular corrosion resistance.

Fe
Iron
The primary base metal that forms the structural matrix of the alloy providing overall strength and durability.
Cr
Chromium
Enhances corrosion resistance by forming a stable oxide layer that protects the steel surface from oxidation and chemical attack.
Ni
Nickel
Improves toughness, ductility, and resistance to oxidation, especially in elevated temperature environments.
Nb
Niobium
Acts as a stabilizing element that prevents chromium carbide formation, helping to resist intergranular corrosion during welding and high-temperature exposure.
C
Carbon
Contributes to strength and hardness; in the higher-carbon 347H variant, it also improves high-temperature creep resistance.
Mn
Manganese
Supports strength and toughness while improving the alloy's hot working and manufacturing characteristics.
Si
Silicon
Functions as a deoxidizing agent during steel production and helps improve resistance to oxidation at high temperatures.
P
Phosphorus
Present in controlled amounts; it can increase strength but is kept minimal to maintain ductility and corrosion resistance.
