EN31 Steel

UK deliveries. Contact our well informed sales team. EN31 is a high carbon alloy steel which achieves a high degree of hardness with compressive strength and abrasion resistance. Forging: Forge at 1000?/1050?C. Heat slowly, allowing sufficient time at the forging temperature for the steel to be thoroughly soaked through. Re-heat as often as necessary to keep the temperature above 850?C. After forging cool very slowly, preferably in a furnace. Annealing: Heat uniformly to 800?C, equalise, then furnace cool. (Hardness about 229 Brinell). Stress Relieving: If machining operations have been heavy or if the tool has an unbalanced section, remove stresses before hardening by heating up to 700?C, equalise, then cool slowly. Hardening: Heat uniformly to 800/820?C until heated through. Allow 30 minutes per inch of ruling section and quench immediately in oil. Tempering: Heat uniformly and thoroughly at the selected tempering temperatures and hold for at least one hour per inch of total thickness.
