321 Stainless Steel Medium Thick Plate Manufacturing Process

321 stainless medium thick plate is usually processed by rolling technique on heavy stainless steel plates. It includes hot rolling and cold rolling.

1. Hot Rolling

The billet will be heated to a certain temperature to fabricate during the hot rolling process. The manufacturing process includes:

Preparing billets — putting into the furnace — heating — pickling — annealing — rolling — heating — annealing — rolling (second time) — sizing — straightening — leveling — cooling — examining — testing — packing — waiting for sale

2. Cold Rolling

Using the hot rolled 321 stainless medium thick plate as the substrate, it is usually rolled at room temperature. 321 Cold rolled stainless steel medium thick plate has a brighter finish, more precise size, and better processing ability than 321 hot rolled stainless steel medium thick plates.


321 Stainless Steel Medium Thick Plate Properties

This plate possesses several notable properties that render it a popular choice in various industries. These properties include:

1. Excellent Corrosion Resistance

One of the key advantages of 321 stainless steel medium thick plate is its exceptional corrosion resistance. This alloy, containing titanium, serves to stabilize the material against the precipitation of chromium carbide, thereby preventing intergranular corrosion. Consequently, it can withstand exposure to corrosive environments, such as acids, alkalis, and high-temperature gases, making it eminently suitable for applications in chemical processing, petroleum refining, and power generation.

2. High Heat Resistance

It exhibits excellent resistance to heat, thereby enabling it to maintain its mechanical properties even at elevated temperatures. With a maximum operating temperature of 900°C (1652°F), it can endure high-temperature environments without any substantial loss of strength or deformation. This commendable attribute renders it ideal for applications in heat exchangers, furnace components, and exhaust systems in the automotive and aerospace industries.

3. Great Strength and Durability

The strength and durability of 321 stainless steel medium thick plate make it eminently suitable for demanding applications. It possesses a higher tensile strength and yield strength compared to other austenitic stainless steels, thus ensuring its ability to withstand heavy loads and mechanical stress. Moreover, its exceptional toughness and resistance to fatigue and creep deformation contribute to its long-term durability, rendering it a reliable choice for structural components in various industries.

4. Good Weldability

321 stainless steel medium thick plate offers good weldability, facilitating easy fabrication and joining. It can be welded using common techniques such as shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), and plasma arc welding (PAW). The presence of titanium in the alloy serves to prevent the formation of detrimental carbides during welding, thereby reducing the risk of weld decay and preserving the material’s corrosion resistance.
