347 347H Stainless steel bar

347 and 347H are both austenitic stainless steel grades that are stabilized with columbium (niobium) and are commonly used in high-temperature applications. The "H" in 347H stands for "high carbon," indicating that it has a higher carbon content compared to standard 347 stainless steel.
