Cold Forming | P420M HT has excellent cold forming properties. The only thing to note is that cold forming at temperatures below 150 °C leads to an increase of the hardness and a decrease of the toughness. These changes in mechanical properties can be partially recovered by a subsequent stress relieving. In case of higher cold forming ratios it is advisable to consult the steel manufacturer prior to placing the order or to monitor the effect of cold forming. Regulations for pressure vessels limit cold forming, if no additional normalising or quenching and tempering is performed. This demand can restrict the use of TMCP-steel for construction parts with a high cold forming rate. P420M HT has excellent forming properties up to a temperature of 600 °C. Forming at temperatures above 600 °C leads to changes in the original microstructure and cannot be recommended. It is impossible to reestablish the same material properties that had been achieved during the original manufacture through a further heat treatment. | |
Heat Treatment | The stress relieving is carried out between 530 and 600 °C followed by cooling in still air. The total holding time should not exceed 150 minutes, even if several operations are carried out. With holding times of more than 90 minutes the lower limit of the temperature range should to be aimed at. Flame straightening should be carried according to special work instruction (see Technical Information of Dillinger “DI-MC - Structural steels“). | |
Supplier Disclaimer | The given information is a rough description and some properties can depend on various factors such as product thickness. Please contact the supplier or refer to the related norm or standard for further information. | |
Welding | P420M HT has an excellent weldability if the general technical rules are observed (see SEW 088 or EN 1011). The risk of cold cracking is low which can be concluded from the low values for Pcm and CET. Hardening of the heat affected zone is low. For a wide range of welding parameters excellent properties in the HAZ have been reached. |
