Fabrication, Bending, Post-Delivery Heating and Welding


Free bending should be performed utilizing maximum allowable bend radius to prevent cracking. TruSTRENGTH 100 plates can be bent using a minimum radius of 1.5T in the longitudinal direction and 2T in the transverse direction. Larger bend radius is recommended for thicker plates. Transverse radius is the bend line parallel to rolling direction.

Welding TruSTRENGTH 100 plate can be welded by conventional processes such as SMAW, SAW and GMAW, provided that the weld procedures used are suitable for this grade and design of the welded structure, using low hydrogen conditions.

*These statements are general guidelines. CMC Impact Metals is not responsible for the results of any welding work performed.
