Grade 347/347H Stainless Steel Plate
Stainless Metal Grades to Fit Your Needs
Grade 347 stainless steel is an 18/8 chromium-nickel alloy reinforced by columbium and tantalum. Generally used in the 800-1500°F temperature range, the columbium stabilizes it and makes it immune to carbine precipitation. Thus, it offers excellent intergranular corrosion and oxidation resistance after exposure to these elevated temperatures. Also, it possesses higher creep and rupture properties than 304/304L stainless steel.
Grade 347H contains more carbon (between 0.04% to 0.1%) than regular 347 (≥ 0.08%), which improves the creep properties and strength at temperatures above 1000°F. While it excels in high-temperature conditions, Grade 347 stainless steel plate also demonstrates excellent toughness in cryogenic temperatures.

Choosing 347/347H Plate from Sabre
While both ASTM A240 grade 347 & 347H stainless steel plate can be hardened only by cold working (and not heat treatment), they can be easily welded and formed using standard steel processing and fabrication practices.
key advantages and benefits include
- Superior resistance to intergranular corrosion
- High strength, creep, and stress rupture properties
- Excellent performance in extremely high-temperature conditions
- Outstanding welding and forming characteristics
- Good toughness in subzero temperatures
- Non-magnetic in the annealed condition
- Resists oxidation up to 1500°F
