Global leader in stainless steel sheet fabrication services
Daxun 321 Stainless Steel Plate (UNS S32100) is a titanium-stabilized austenitic stainless steel with excellent resistance to intergranular corrosion. This grade is designed for high temperature applications up to 1500°F (815°C), where the addition of titanium stabilizes the material against the formation of chromium carbides. Since titanium has a greater affinity for carbon than chromium, titanium carbides occur within the grains rather than at the grain boundaries. While its annealed corrosion resistance is comparable to 304 and 304L, it has stronger creep and stress rupture properties. These properties make it suitable for pressure vessel and boiler applications. 321 Stainless Steel is non-magnetic and heat resistant, allowing long-term use at high temperatures.
Daxun Alloys stocks 321 Alloy stainless steel plate in thicknesses ranging from 3/16″ to 4″. You can also order the high carbon version 321H Alloy (UNS S32109) in the same thickness range.The alloy can be used in most dilute organic acids at moderate temperatures, pure phosphoric acid at lower temperatures, and dilute solutions up to 10% at elevated temperatures. Alloy 321 resists polythionic acid stress corrosion cracking in hydrocarbon service. It can also be used in alkaline solutions without chlorides or fluorides at moderate temperatures. Alloy 321 does not perform well in chloride solutions (even at low concentrations) or in sulfuric acid environments.

What is the difference between 321H stainless steel plate and 321?
321 and 321H stainless steel plates have different degrees of strength and corrosion resistance. Stainless steel 321 is a non-heat-treatable type that is usually used in applications where toughness and weldability are critical. In contrast, 321H stainless steel is heat-treated to increase its strength at high temperatures and improve its formability. It is often used in more demanding environments, and its ability to withstand high temperatures makes it the material of choice. Ultimately, the requirements of the application, including those related to temperature, strength, corrosion resistance, and formability, will determine which grade is best.
What does 321 stainless steel plate consist of?
Alloy 321 stainless steel plate is made of titanium, nickel, and chromium, which provides excellent heat and corrosion resistance. Because it does not harden or deform at extremely high temperatures, it is a recommended choice for high-temperature applications. The unique look and feel of 321 stainless steel, attractive for both indoor and outdoor applications, is also a result of its high chromium and titanium content. Many industries, especially aerospace, use this high-quality steel to complete challenging projects that require durability, strength, and accuracy.
Contact the top suppliers in China for stainless steel sheets (steel plates) in a variety of finishes. You need no other stainless steel sheet supplier than Daxun Alloys, who offer free cutting services and delivery times as short as 5-7 days.
321 Grade Stainless Steel Sheets in a Variety of Finishes
Our stainless steel sheets (sometimes called steel sheets) are available in a range of beautiful finishes: brushed finish, 2B smooth finish or 8K mirror finish.
The finished side of each stainless steel sheet we supply is coated with a film. This film is easily peeled off after fabrication or installation and protects the surface of the material from wear and marks. The back side is unfinished.
321 Grade Stainless Steel Sheet is the most commonly used variety. It is easily weldable, formable, and has good corrosion resistance.
We can assist in providing stainless steel sheets in any required size.
To meet your specific requirements, our stainless steel sheets are available in three finishes and a variety of sizes. We can readily provide any custom size you may need with our free unlimited cutting service.
We are able to meet any size needs between 0.3 and 30 mm in thickness and between 50 x 50 mm and 2500 x 1250 mm in size. In addition, we provide free unlimited cutting with every order, using a state-of-the-art cutting machine to precisely meet your requirements.
Order Stainless Steel Sheets by Phone or Online.

Characteristics:
This grade is more resistant to corrosion and pitting than 304 and offers higher strength at elevated temperatures. In addition, 316L is an extra low carbon variation that helps avoid carbide precipitation due to welding.
Important Safety Note:
The edges of the metal sheets we sell are not polished, ground or finished, so they may be sharp, just like the edges of any stainless steel sheet. We remind users to use, install and handle these devices with care.
We can provide stainless steel sheet samples for you to check the quality. Sample is free and you just pay the freight.
We’ve exported to more than 42 countries, such as Canada, Chile, Kuwait, Germany, South Korea, Saudi Arabia, Singapore etc.
Our MOQ is 1 ton for stainless steel sheet.
Trial orders can be delivered within a week. For regular orders, it takes two weeks roughly.
