Superior 310S Flat Bars for Furnace Components
We ordered 6 tons of 310S stainless steel flat bar (20mm x 150mm, hot-rolled finish) for our high-temperature furnace fixture manufacturing project. Material certificates showed chromium content at 25.1% and nickel at 20.3%, fully compliant with ASTM A276 specifications for oxidation resistance up to 1150°C. We conducted elevated temperature tensile testing at 900°C and results exceeded our requirements with yield strength maintaining 140 MPa. Surface condition was excellent with uniform oxide scale typical of hot-rolled production. What impressed us most was the dimensional accuracy with thickness tolerance of ±0.4mm across the entire order. The bars maintained straightness within 2mm per meter length, exceptional for this size range. This is our 3rd specialized order for heat treatment applications. Highly recommended for furnace and kiln construction projects requiring extreme temperature stability.
