321H Stainless Steel Sheet Plate 1000-2200mm Width High Rust Resistance
what is 321H Stainless Steel Plate?
321H steel is a high-carbon stainless steel with a higher chromium content than 304H. It has excellent corrosion resistance, good weldability and formability, and high-temperature properties. It is suitable for applications up to about 900°C and can be used in more aggressive environments than 304H. It is also non-magnetic and has a higher strength-to-weight ratio than 304H. Some of its general properties include:
• High strength
• High corrosion resistance
• Good weldability and formability
• Non-magnetic
• High-temperature properties
• High strength-to-weight ratio
