Fabrication, Bending, Post-Delivery Heating and Welding
| Bending | Free bending should be performed utilizing maximum allowable bend radius to prevent cracking. TruSTRENGTH 140 plates can be bent using a minimum radius of 3T in the transverse and longitudinal direction. Larger bend radius is recommended for thicker plates. Transverse radius is the bend line parallel to rolling direction. |
| Welding | TruSTRENGTH 140 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.
Standard Delivery Conditions
| Surface Finish | Shot blasting and rust preventative applications are available. Please inquire. |
| Test Reports | Supplied with shipment for each production lot in the shipment. Reports include product description, heat number, chemical analysis and Brinell hardness value. |
