DIWA 373 (EN 1.6368)

Boilers in accordance with EN 12952/ EN12953 (TRD 101) for temperatures up to 500 °C.

Pressure vessels in accordance with AD 2000-Merkblatt W1, HP 8/1, EN 13445 and CODAP 2005 fortemperatures from -20 °C up to 500 °C.

DIWA 373 can be cold formed according to the general procedures.CEN/TR 10347 (Guidance for forming of structural steels in processing) as well as the provisions of VdTÜV-material data sheet 377/1 shall be observed.

Delivery condition:

thicknesses ≤ 100 mm normalized and tempered

thicknesses> 100 mm normalized and tempered or water quenched and tempered

In accordance with EN 10028-2 a water quenching and tempering treatment is already possible for thick-nesses equal or superior to 100 mm.

If the heat treatment is to be performed during processing, the plates can be delivered in the normalizedcondition, and in exceptional cases in the as rolled condition by special agreement before the order. In thiscase testing of the mechanical properties is provided on the basis of simulated heat treated specimens.

DIWA 373 can be welded and flame cut according to the general procedures.The guidelines given in EN 1011 (Welding), as well as the provisions of VdTÜV-material data sheet 377/1 shall be observed.

If special requirements, which are not listed in this material specification, are to be met by the steel due to its intended use or processing, these requirements are to be agreed before the order.

DIWA 373 can be hot formed according to the general procedures.CEN/TR 10347 (Guidance for forming of structural steels in processing) as well as the provisions of VdTÜV-material data sheet 377/1 shall be observed.

Fully killed, fine grained steel with metallurgical treatment in the ladle.

The entire processing and application techniques are of fundamental importance to the reliability of theproducts made from this steel. The user should ensure that his design, construction and processing meth-ods are aligned with the material, correspond to the state-of-the-art that the fabricator has to comply withand are suitable for the intended use. The customer is responsible for the selection of the material. Therecommendations in accordance with EN 1011-2 should be observed.

Surface condition:Unless otherwise agreed, the provisions in accordance with class B2 of EN 10163-2 are applicable.

Sampling, testing method and tests are in accordance with the provisions in EN 10028. For orders in accor-dance with VdTÜV material data sheet 377/1, the conditions indicated there are respected. Additional tests can be agreed upon. The plates are delivered with inspection certificate 3.1 or 3.2 in accordance withEN 10204. The document type and, in case of inspection certificate 3.2, the inspection representative are tobe stated on the order.

Tensile test at ambient temperature (transverse test specimens), Tensile test at elevated temperature (transverse specimens in accordance with 10028-2)

For plate thicknesses ≥ 15 mm, the fulfilment of one of the three quality classes Z15, Z25 or Z35 in accordance with EN 10164 or similar standards can be stipulated on the order.

Tolerances:Unless otherwise agreed, tolerances are in accordance with EN 10029, with class B for the thickness andclass N for the flatness.
