Key features

Every Q345R and 15CrMoR hot rolled steel plate is ultrasonically tested to ASTM A435, ensuring a defect-free building material for boilers and reactors operating under high pressure.

15CrMoR and 12Cr1MoVR hot rolled steel plates resist hydrogen attack and creep at temperatures up to 550 Celsius, making them the trusted steel material for petrochemical reactor shells.

Our hot rolled steel plates up to 2500mm width minimize longitudinal weld seams in large-diameter boiler drums and pressure vessels, reducing fabrication cost and inspection requirements.

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 Q245R and Q345R hot rolled steel for pressure vessels?

Q245R is a carbon-manganese hot rolled steel plate with minimum yield strength of 245 MPa, suitable for medium-temperature, moderate-pressure vessels. Q345R offers higher strength (345 MPa yield) with added manganese and silicon, allowing thinner wall designs for higher pressure or lower weight vessels.

Q:Do you provide hot rolled steel plates with EN 10204 3.2 certification for ASME vessels?

Yes, our Q345R, 15CrMoR, and SA387 hot rolled steel plates can be supplied with EN 10204 3.2 certification witnessed by Lloyd's Register, Bureau Veritas or SGS. Full ultrasonic testing and elevated temperature tensile testing documentation are provided.

Q:What Cr-Mo grade do you recommend for a hydrogen reactor operating at 500 Celsius?

For hydrogen service at 500 Celsius , we recommend 15CrMoR or SA387 GR12 hot rolled steel plate. The chromium (1.0-1.5%) and molybdenum (0.45-0.65%) content provides resistance to hydrogen attack and maintains creep strength at elevated temperatures. For more aggressive conditions, 12Cr1MoVR with higher Cr content is available.
