PRODUCT INTRODUCTION

310 stainless steel plate is a high-alloy material with excellent oxidation resistance, corrosion resistance, and high temperature strength. The superior oxidation resistance comes from the formation of a stable chromium oxide (Cr₂O₃) layer on the surface, which protects the metal from further oxidation.

With a chromium content of at least 20% and nickel-enhanced alloying, ASTM 310 stainless steel maintains strength and durability at elevated temperatures. It is widely used in high-temperature equipment and industrial applications.

FEATURES

• ✅ Excellent oxidation and corrosion resistance

• ✅ High-temperature resistance up to ~1000°C

• ✅ Strong mechanical properties: tensile strength ≥ 520 MPa, yield strength ≥ 205 MPa, elongation ≥ 40%

• ✅ Easy to cut and process

• ✅ Lightweight and durable

APPLICATION

• Heat exchangers and furnace components

• Combustion chambers and furnace doors/walls

• Gas turbine components

• Incinerators and recuperators

• Welding filler metal and high-temperature industrial equipment

ADVANTAGES

• Can withstand harsh chemical environments (acid, alkali, salt)

• Superior performance at high temperatures compared to standard stainless steels like 304 or 316

• Smooth surface and consistent quality for industrial fabrication

• Suitable for both OEM and custom engineering applications
