EN31 rod suppliers in UAE
The demand for high-quality steel is on the rise for making wear-resisting machine parts and press tools. EN 31 is a high carbon steel with 1% molybdenum and chromium content suitable for solving complex problems. Experienced suppliers supply EN318 steel in spheroidicity condition for many applications like making swaging dies, gauges, taps, ball bearings, etc.
EN31 round bar made of an important high carbon steel alloy of the E series offers a high degree of hardness, abrasion resistance, and compressive strength useful for many applications. High chromium of 1.2 to 1.6% makes it resistant to corrosion even at high temperatures. It is because of its high tensile and yield strength of 750 and 450 N/mm2, respectively.

What is EN31 Rod hardness?
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 in spheroidized condition have high 230 Brinell hardness. Also It has high ductility, easy machinability and reduces energy for subsequent operations.

Can EN31 be welded?
EN31 Steel Bar is hard with high carbon but easy to weld. Reputed suppliers provide it in spheroidized condition. EN 31D steel bar is useful in manufacturing where 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.
Several studies were conducted using different welding methods for Carbon steel EN-31B hex bars. Researchers concluded GMAW or gas metal arc welding with wire speed from 150 to 240 inches per minute using dimensional and kinetic analysis.

Yes. Case hardening EN31 round bars is possible using GTA or gas tungsten arc welding method. Also Cryogenic treatment is essential for further improving its surface hardness. A 2% thoriated tungsten electrode helps to apply heat on the friction surface to improve its hardness.
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.
