AISI 4130 Steel - 25CrMo4 - JIS SCM430 - GB 30CrMo

Heat to 900º C (1650 º F). Cool 4130 steel in air. Actually, when forgings are normalized before, say, carburizing or hardening and tempering, the upper range of normalizing temperatures is used. When normalizing is the final heat treatment, the lower temperature range is used. Hardening. Austenitize at 870º C (1600 º F), and quench in oil. AISI 4340 Steel - JIS SNCM439 - DIN 1.6563 - Songshun SteelFollowing quenching to hand warm, tempering at 150°C 200°C will reduce stresses in the case with minimal effect on its hardness. All de-carburized surface material must first be removed to ensure the best results. Nitriding. Hardened and tempered 4340 alloy steel can also be nitrided, giving a surface hardness of up to Rc 60. ASTM SAE AISI 1045 Carbon Steel Heat - The World MaterialThe austenitizing temperature for SAE 1045 induction hardening carbon steel is 800-845 °C. Full Annealing. The annealing temperature for AISI 1045 carbon steel is from 790-870 °C, cooling cycle from 790 to 650 °C at a rate of 28 °C/h in furnace, and can get the HBW hardness range from 156 to 217.

Engineering steel material EN19 hardness in HRC:Flame or induction hardening can give a case hardness of 50 HRC or higher. EN19 equivalent material with AISI 4140, DIN 42CrMo4 EN 1.7225, GB 42CrMo, JIS SCM440C alloy engineering steel. Mechanical properties of steel EN19 (1.7225) Hot Rolled Steel C1141 Metal Supermarkets - Steel Grade Summary:Grade C1141 is a medium-carbon steel with higher mechanical properties than other medium carbon steels, as well as free machining properties. It has a fine-grain structure, with high consistency and uniformity, and is high strength as-rolled. Because of the free machining properties, it is usually used in automatic screw machines Typical Applications:Axles, Pins, Order 1" Alloy Steel Round Bar 4130-Normalized Cold Finish Alloy Steel Round Bar 4130 Normalized Cold Finish offers good strength and weldability without compromising steel abrasion or impact resistance. This material comes in the normalized condition and doesn't require further heat treatment. It is typically used in structural applications, gears, fasteners, and aircraft exteriors.

PRACTICAL HARDNESS TESTING MADE SIMPLE

if the tested material is too thin (less than 9.6 mm or 3/8 ") so that a mark appears on the opposite side if the tested material is too hard (more than 450 HBS for steel ball or more than 650 HBW for tungsten carbide ball). The letters HBS stand for Hardness Brinell with Steel ball, (HBW for tungsten carbide ball) but the qualification Quenching and tempering - tec-scienceDepending on whether a high hardness (hardening) or strength/toughness (strengthening) has to be achieved, the final process, the so-called tempering, is carried out at different temperatures. When a steel has to become very hard, it is only tempered at relatively low temperatures in the range of 200 °C to 400 °C, while it becomes tougher and high load capacity at higher Speedy Metals Information for A2 Tool Steel PlateIf maximum hardness is desired, tempering should be in the range of 300-400°F, but if a lower hardness is acceptable, tempering at 950°F will give the optimum combination of hardness and toughness. The Rockwell C hardness obtained on specimens 1 inch square when quenched in air from 1775°F and tempered at various temperatures, held for 4
