EN 31 Rod hardness is high as it gets supplied in the spheroidicity condition. It involves slowly heating the high carbon steel alloy with molybdenum and chromium to harden 800 to 820 C. And cooling the heated steel for a long time by quenching it in oil. Hence EN 31 steel hardness goes up to 63 HRC during different spheroidized conditions.
EN-31B Flat Bars supplied in spheroidized condition have a 230 Brinell hardness. It has high ductility, easy machinability, and reduces energy for subsequent operations.

EN31 Steel Bar is easy to weld even though it is hard with high carbon and supplied in spheroidized condition. EN 31D steel bar is useful in manufacturing processes, and welding becomes essential. Many studies confirm different welding methods for EN 31 steel that does not affect its mechanical properties. It included MIG or metal arc welding using a continuous solid wire electrode heated and fed using a welding gun into the weld pool.
Many studies were conducted using several welding methods for Carbon steel EN-31B hex bars. Using dimensional and kinetic analysis, researchers concluded GMAW or gas metal arc welding with welding wire speed from 150 to 240 inches per minute.

Yes. Case hardening EN31 round bars is possible using GTA or gas tungsten ar. For further improving the surface hardness, it is advisable to have a cryogenic treatment. It uses a 2% thoriated tungsten electrode for applying heat on the friction surface.
Case hardening of CS EN-31B Square Bars using CHT or conventional heat treatments like annealing, hardening, normalizing, tempering, quenching, and stress relieving is possible. Cryogenic treatment after CHT procedures enhances the mechanical properties to withstand wear and tear in many complex applications like machining parts.
