Technological properties
| Property | ||
|---|---|---|
| Application areas | Tank installations in accordance with RID/ADR as well as EN 14025 Pressure vessels in accordance with AD 2000 Merkblatt, EN13445, CODAP 2005 | |
| Cold Forming | The plates can be hot or cold formed. Even in case of appropriate hot forming an additional tempering can be necessary particularly for thin plates due to the accelerated cooling within the forming tool. | |
| Delivery condtion | Normalized, unless otherwise agreed. General technical delivery requirements: Unless otherwise agreed, the general technical delivery requirements in accordance with EN 10021 apply. An additional tempering in accordance with EN 10028-3:2009 may be performed. Should a PWHT be necessary the testing of the mechanical properties on the basis of simulating post weld heat treated specimens can be agreed upon. This optional testing (option 1) is to be indicated on the order and is performed instead of testing in the delivery condition. | |
| Flame cutting and welding | The suitability of DILLINAL 460/630 for flame cutting and welding has been proven. The verification of the toughness properties is performed on welding specimens with basic filler metal and a cooling time t8/5 in the range between 8 and 25 seconds. In case of high toughness requirements it may be necessary to reduce the heat input so that the t8/5 time is below 20 seconds. In any case welding shall be performed in multi pass technique with flat welding passes and good grain refinement. | |
| General note | If special requirements, which are not listed in this material data sheet, are to be met by the steel due to its intended use or processing, these requirements are to be agreed before placing the order. The information in this data sheet is a product description. This data sheet is updated as occasion demands. The current version is available from the mill or as download at www.dillinger.de. | |
| Heat Treatment | If stress-relieving treatment is necessary, this is usually performed on the finished welded vessel. The stress-relieving treatment should be performed at temperatures between 530 °C to 560 °C, as higher temperatures lead to reduced toughness properties in the weld. The time-temperature-parameter P in accordance with EN 10028-3 must not exceed the value 16.7 for DILLINAL 460/630 N and 16.35 for DILLINAL 460/630 NL. The holding time should not exceed 150 minutes even for heat treatments in several cycles. For holding time above 90 minutes the lower limit of the temperature range should be aimed at. The subssequent cooling is performed in still air. The stress-relieving treatment can be omitted if no corrosive media will be transported in the vessels and if allowed by the applicable regulations. | |
| Hot forming | The plates can be hot or cold formed. Even in case of appropriate hot forming an additional tempering can be necessary particularly for thin plates due to the accelerated cooling within the forming tool. | |
| Other | Identification: Unless otherwise agreed the marking is carried out via low stress steel stamps with at least the following information: | |
| Processing history | BOF-converter process and metallurgical ladle treatment. Fully killed, fine grained steel with addition of nitrogen fixing elements. | |
| Processing methods | The entire processing and application techniques are of fundamental importance to the reliability of the products made from this steel. The user should ensure that his design, calculation and processing methods are aligned with the material, correspond to the state-of-the-art that the fabricator has to comply with and are suitable for the intended use. The customer is responsible for the selection of the material. The recommendations in accordance with EN 1011-2 should be observed. | |
| Surface condition | Surface condition: Unless otherwise agreed, the provisions in accordance with class B2 of EN 10163-2 are applicable. | |
| Testings | The testing of the mechanical properties is performed on specimens in the condition normalized (N) or normalized and tempered (N+T) . Sampling, testing method and tests are in accordance with EN 10028-1, unless otherwise stipulated or agreed. The plates can be delivered with inspection certificate 3.1 or 3.2 in accordance with EN 10204. The kind of the inspection certificate has to be specified on the order. | |
| Tolerances | Unless otherwise agreed, tolerances are in accordance with EN 10029, with class B for the thickness. | |
