Key features

From cost-effective aluminized automobile steel sheet for heat shields to AISI 321 for turbo downpipes, one supplier covers every exhaust system temperature zone.

AISI 409 and 441 automobile steel sheets resist intergranular corrosion at weld zones and maintain thermal fatigue strength through thousands of heating and cooling cycles.

Our aluminized automobile steel sheet withstands 550 degree Celsius continuous service with 95% infrared reflectivity, making it the economical choice for heat shields and thermal barriers.

AI-Powered supplier vetting

SummaryCNB NEW MATERIAL (TIANJIN) CO., LTD. is a China-based trading company established in 2023 with three employees. It reports quality assurance, raw-material traceability, written inspection instructions, in-stock capability, and customization from samples or designs. The company states that 90% of sales are exports and cites international companies as fixed raw-material customers, although no specific case details are provided. Service reach is limited: it reports no overseas agents or branches, overseas warehouses, overseas showroom, offline trade-show participation, or overseas service countries. R&D evidence is weak, with no new product information in the past year, no ODM, no SDK, and no branded OEM capability. Financial information provided shows zero operating revenue and zero profit-related figures for the stated periods, requiring caution. Outsourcing procedures, manufacturing-capacity contracts, corrective-action records, complaint-handling records, and supplier-assessment records are incomplete or...

Financial creditThe submitted financial slices report zero operating revenue and zero profit-related figures for the stated periods, while current ratios are also reported as zero. These figures do not demonstrate financial strength and indicate a material need for verification before relying on the supplier’s financial capacity.

R&D capabilityThe supplier reports no new product information during the past year, no ODM service, and no available SDK. Although it can customize from samples and designs, the provided evidence does not support strong independent R&D or innovation capability.

Customization capabilityCustomization from samples and customization from designs are explicitly available through both design services and R&D-related services. This supports the supplier’s ability to handle customer-specific requirements, although no evidence is provided regarding production scale or technical complexity.

Client casesThe supplier states that it has become a fixed raw-material supplier to Panasonic, Toyota, Honda, IKEA, and Komatsu, and reports that 90% of total sales are exports. These named customer claims provide positive case evidence, but the slices do not include order scope, duration, product details, or independently verifiable references.

Product Q&A

Q:What is the difference between AISI 409 and AISI 441 automobile steel for exhaust manifolds?

AISI 409 automobile steel is the standard ferritic stainless for exhaust systems, with 10.5-11.7% Cr and Ti stabilization for good weldability and oxidation resistance up to 800 degree Celsius. AISI 441 automobile steel has higher chromium (17.5-19.5%) with dual Ti and Nb stabilization, providing superior oxidation resistance and creep strength at temperatures above 900 degree Celsius, making it preferred for close-coupled catalytic converters and performance exhaust manifolds.

Q:Can your aluminized automobile steel sheet replace stainless steel in exhaust applications?

For heat shields, muffler outer wraps, and thermal barriers up to 550 degree Celsius, aluminized automobile steel sheet is a cost-effective alternative to stainless steel. For hot-end components like exhaust manifolds and catalytic converter shells where temperatures exceed 600 degree Celsius, stainless grades remain necessary.

Q:Do you supply automobile steel in slit coil widths for exhaust tube production?

Yes, we slit automobile steel coils to your specified width for tube mill production of exhaust pipes, with tight width tolerance and minimal burr. This is available across aluminized, 409, 441, 304, and 321 grades. Minimum slit width depends on material thickness and grade.
