Applications
Cold working
Cold working (bending, calendering, shearing, punching, etc.) of DILLIMAX® – QUEND® – STRENX® 700 steel plates presents no particular difficulties, provided specific characteristics are taken into due consideration. Given the high strength of these steels, a greater force must be applied compared to normal carbon steel to obtain the same degree of deformation. For cold bending, it is important to comply with the minimum curvature radii provided in the table, which are applicable when the spindle axis is perpendicular to the final milling direction (plate length)
Hot working
Hot working (bending and forming) of DILLIMAX® – QUEND® – STRENX® steels can be conducted using the same techniques that are normally used for carbon and alloy steels. However, it is important to keep in mind that, because of the particular state in which DILLIMAX® – QUEND® – STRENX® steels are supplied, mechanical properties must be restored via a heating process after hot working, when this is performed at temperatures higher than the tempering temperature. We recommend that the temperature used to heat the piece to be worked on does not exceed 1000 °C.
Oxy-fuel cutting
Oxy-fuel cutting of DILLIMAX® – QUEND® – STRENX® steels does not require any particular techniques or precautions. Keep in mind, however, that the cut surface will be hardened by the thermal cycle produced by cutting for a minimal depth. This phenomenon becomes relevant if the part that has been cut by oxy-fuel needs to undergo further mechanical engineering work.
In this case, it is appropriate to conduct localised tempering, which must be carried out very carefully, making sure the temperature does not exceed 600°C.
Weldability
DILLIMAX® – QUEND® – STRENX® steels are perfectly suitable for welding, provided appropriate electrodes, fluxes and welding techniques are used. Weld materials can be obtained from the main national and international manufacturers.
