Our 321/321H stainless steel cold-rolled plates are produced using advanced precision cold rolling, solution annealing, and fine finishing processes. Each plate undergoes 100% spectrometric chemical composition analysis, ultrasonic testing, and hardness inspection, and is delivered with an EN 10204 3.1 material certificate to ensure full traceability and compliance. The long-term safe operating temperature of 321 stainless steel cold-rolled plate reaches up to 870°C, while 321H alloy cold-rolled plate can be used at temperatures up to 925°C, with short-term heat resistance up to 1150°C. These properties make them widely used in boiler superheaters, heat exchangers, chemical reactors, high-temperature furnace linings, and aerospace components.
The 321/321H stainless steel plates are available in thicknesses ranging from 0.3–6.0 mm, widths of 1000–1500 mm, and lengths of 2000–6000 mm.

FAQ
Q: Can we visit your factory?
A: Warmly welcome. Once we have your schedule, we will arrange the professional sales team to follow up your case.
Q: Can you provide OEM/ODM service?
A: Yes. Please feel free to contact us for more detail discussion.
Q.Is 321 stainless better than 316?
A.The stainless steel 321 works best at higher temperatures. The titanium in it helps to prevent the brittleness in them when the stainless steel is exposed to more heat for a longer period of time. Stainless steel 316 has a high impact of resistance at the low temperatures making them tougher in cold environments.
