How to distinguish 304 and 201 stainless steel?

304 has better quality, higher nickel content, and superior corrosion resistance compared to 201. 304 is typically imported with 18Cr-9Ni composition, while 201 is domestic with 17Cr-4.5Ni-6Mn-N and is more prone to rust.

AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier serving nuclear, food processing, coal gasification, environmental protection, and aerospace industries. It offers broad customization, including sample-, design-, full-, minor-, and flexible customization, supported by CAD and documented design inputs, outputs, reviews, verification, and validation. However, it does not provide 3D software design, ODM, SDK, private mold, or well-known-brand OEM services, and reported no new products in the past year. Export experience is established, with 13 years of exporting and 71%–90% of sales from exports, but no overseas showroom, agent, branch, or offline trade-show participation. ERP, OA, CRM, SAP, digitalization, and big-data initiatives are reported. Complaint handling and corrective/preventive action lack written procedures or records, while certification, financial credibility, production capacity, and customer cases are insufficiently evidenced.

Supplier typeThe supplier explicitly identifies as a professional technical supplier and describes service orientation toward nuclear, food processing, coal gasification, environmental protection, and aerospace industries. This supports classification as an industry-focused technical supplier rather than a general trading entity.

After-Sales capabilityThe supplier has no overseas showroom, agent, branch, or offline trade-show history, and reports no written procedures or records for complaint handling or corrective and preventive actions. These explicit limitations indicate weakly documented after-sales and service-support capability.

R&D capabilityThe supplier has R&D-related design documentation and CAD capability, but reports no new products in the past year, no ODM, no SDK, no patents, and no private mold designs. The evidence shows basic design capability but also explicit limitations in recent product innovation and proprietary development.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization, supported by CAD and documented design review, verification, and validation materials. This is direct evidence of broad customization capability, although the supplier does not offer 3D software design services or private molds.
