En 10204 Pdf Hot -

The EN 10204:2004 standard is a global benchmark for material traceability, defining four types of inspection documents supplied to purchasers of metallic products. It ensures that materials like steel plates, bars, and forgings comply with technical delivery conditions. Hierarchy of Certification Types

The standard categorizes documents based on the level of inspection and the independence of the authorized representative.

EN 10204 3.1 Vs 3.2 — Free Certificate Checklist (PDF Guide) en 10204 pdf hot

The EN 10204 standard is the international benchmark for certifying the quality and traceability of metallic products, including hot-rolled steel. It specifies the types of inspection documents a manufacturer must provide to prove that a delivery meets the customer's specific order requirements. Core Certificate Types (EN 10204:2004)

The current 2004 version of the standard simplified the requirements into four main document types: The EN 10204:2004 standard is a global benchmark

4. "Hot" Specifics in EN 10204 Documents

When a customer asks for an EN 10204 PDF for a hot product, the document must reflect properties that are unique to hot rolling or hot forming.

D. Testing temperature during hot work (reference only)

While EN 10204 does not require reporting the rolling or forming temperature, many reputable mills include "Final hot rolling temperature" or "Solution annealing temperature" in the remarks section of the PDF. C (Carbon): ≤ 0.22% (Increases strength

C. Microstructure / grain size (if specified)

For certain hot products (e.g., hot-rolled free-cutting steels, case-hardening steels), EN 10204 certificate may include grain size rating (ASTM) or inclusion rating – critical for downstream heat treatment.

B. Inspection Certificates (Specific Inspection)

These are the most requested documents in the industry. They require the product to undergo specific testing, and the results must be traced to the specific delivery.

Mistake #1: Confusing Type 2.2 with Type 3.1

Some suppliers will send a Type 2.2 PDF (no inspector signature) and call it a "certificate." For hot-rolled critical applications, this fails audits. Insist on 3.1.

Section 4: Mechanical Properties

• Yield Strength (ReH): For S355JR, expect 355 MPa minimum.
• Tensile Strength (Rm): For S355JR, expect 470 – 630 MPa.
• Elongation (A%): For S355JR, expect 20-22% minimum.

Section 3: Chemical Composition (Cast Analysis)

Look for these elements in a hot-rolled steel PDF:

• C (Carbon): ≤ 0.22% (Increases strength, decreases weldability)
• Mn (Manganese): 0.50 – 1.60% (Toughness)
• P (Phosphorus): ≤ 0.035% (Low is good)
• S (Sulfur): ≤ 0.035% (Low is good)
