DILLIMAX 500 ML (Fine-Grained High-Strength TMCP Steel Plates)

摘要

Dillimax 500 ML is a high-strength tliermomechanically rolled steel for sophisticated design. Mechanical properties in the delivery condition are given in Table 2. Impact values are shown in Table 3. Welded joints of this alloy are usually used in welded condition. If a stress relief heat treatment is necessary, it is carried out in the temperature range between 530 °C and 560 °C (986 °F and 1040 °F) with cooling in still air. The holding time should not exceed 150 minutes (even if multiple operations are carried out).
