precision ground 310S plate supplier
If you are looking for a high-precision, heat- and corrosion-resistant stainless steel solution, the AISI 310S precision ground stainless steel plate is your ideal choice. Manufactured to tight tolerances and polished to a smooth, flat finish, this grade is widely used in high-temperature industrial applications, precision machinery, and tooling environments.
As a professional stainless steel supplier, GNEE offers high-precision, high-purity precision ground 310S stainless steel plates. Through multiple grinding processes, the surface roughness can reach Ra ≤ 0.02–0.8 μm, achieving a mirror-like finish. Thickness tolerances are strictly controlled within ±0.01–0.03 mm, and the flatness and consistency exceed industry standards-meeting the zero-defect requirements of semiconductor, medical, and high-tech applications.
Advantages
The EN 1.4845 ground stainless steel sheet, containing 24–26% chromium and 19–22% nickel, undergoes precision grinding to eliminate surface imperfections and form a dense, uniform passive layer. It offers long-term resistance to high temperatures up to 1150°C and maintains excellent corrosion resistance against nitric acid, organic acids, and other harsh chemicals. It is ideal for chemical reactors, high-temperature furnace linings, and other extreme environments.
310S precision ground stainless plate is produced in full compliance with ASTM A240, ASME SA240, and other international standards, and is certified by ISO, CE, SGS, ensuring consistent batch quality. GNEE also provides bending, stamping, welding, and other fabrication services to reduce your secondary processing costs.
