Product Overview
High-Performance Stainless Steel Sheets & Heavy Plates
Qiaodi Steel supplies a comprehensive inventory of prime-grade stainless steel sheets, medium plates, and heavy structural plates. Sourced directly from premier steel mills in Wuxi (such as TISCO, BAOSTEEL, and ZPSS), our sheets and plates meet strict international standards, including ASTM A240, EN 10088, and JIS G4305.
Whether you require cold-rolled sheets for precision stamping, hot-rolled plates for heavy construction, or decorative polished finishes, we offer custom shearing, laser cutting, and protective film coating tailored to your exact specifications.
Popular Material Grades
- 304 / 304L Stainless Steel Sheet
- Characteristics: The most versatile and widely used grade. Excellent corrosion resistance, formability, and weldability. Ideal for food processing, architectural trim, and chemical equipment.
- 316 / 316L Stainless Steel Plate
- Characteristics: Marine-grade stainless steel containing molybdenum for superior resistance to chlorides and harsh chemical environments.
- 310S / 321 Heat-Resistant Plate
- Characteristics: High-nickel and chromium alloys designed for high-temperature applications such as furnaces, heat exchangers, and exhaust systems.
- Duplex & Super Duplex Steel Plate (2205 / 2507)
- Characteristics: Combines high yield strength with exceptional resistance to stress corrosion cracking, suitable for offshore oil & gas and chemical processing.
