321 stainless steel is austenitic, containing titanium as its primary alloying element. This gives it excellent resistance to intergranular corrosion, which can be a problem with other austenitic stainless steels like 304.
Here are the key features of 321:
Corrosion Resistance:Excellent resistance to intergranular corrosion due to the titanium stabilization.
High-Temperature Performance:Good resistance to oxidation and scaling at elevated temperatures.
Weldability:Good weldability without the need for post-weld annealing.
Excellent formability and toughness.
Suitable for forming into complex shapes.

Inner and outer diameter
Inner Diameter | 300、400、500（Customized according to the customer's machine size） |
Outer diameter | The outer diameter range is determined based on the width of the material required by the customer and the maximum weight of a single trailer. |
The weight of a single trailer generally does not exceed 2 tons to ensure that the goods will not be damaged during transportation and moving.
Surface
DSM offers a variety of different surface treatments for stainless steel plates. There are1U, 1C, 1D, 1E, 2B, BA, No.4, TR, HL etc.
Edge
The edge of the steel strip is trimmed, and the burr height is 10% mm. If there are special requirements for the edge, it can be scraped.
Supply Form
DSM has a professional team and adopts a variety of packaging standards to ensure that the products arrive at the customer's warehouse intact. After packaging, the product looks neat and beautiful, and it can also prevent rust, moisture, dust, pressure, collision, and scratches. Small wooden blocks are placed in the middle to facilitate customers to move the steel belt.
Optional packaging materials: waterproof paper, blue film, plastic wrap, internal and external corner guards, paper, blue leather, plastic cloth, customized wooden racks, fumigated wooden racks, iron racks, wooden boxes, wooden strips, iron corner guards, wrinkled wire paper, desiccant, isolation board, etc.
