L6 Tool Steel | 1.2713 | 55NiCrMoV6 Product Introduction
L6 Tool Steel (American Standard ASTM)
Composition and Basic Properties: L6 tool steel is an oil-hardening, chromium-nickel tool steel with a typical composition of carbon (0.65%-0.75%), nickel, and chromium (0.60%-1.20%), supplemented by manganese (0.25%-0.80%) and traces of molybdenum (≤ 0.50%).
Heat treatment and properties: hardness of 40-54 HRC after oil quenching (816-843°C) and low-temperature tempering, combining high toughness with moderate wear resistance (industrial rating 2/6). The hardenability is excellent and large cross sections can be hardened uniformly, but strict temperature control is required to avoid cracking and rapid cooling is required after tempering.
1.2713 Tool Steel (DIN, equivalent to 55NiCrMoV6)
Composition and Physical Properties: 1.2713 tool steel is a nickel-chromium-molybdenum-vanadium alloyed tool steel, with a composition of carbon (0.50-0.60%), nickel, chromium (0.60-0.80%), molybdenum (0.25-0.30%) and molybdenum (0.25-0.30%). 0.25%-0.35%) and vanadium (0.07%-0.12%).
Heat treatment and micro-control: oil quenching at 830-860°C, hardness after tempering varies with the temperature gradient (approx. 54 HRC at 200°C tempering, approx. 51 HRC at 300°C). Its high hardenability supports hardness uniformity over large sections (300 mm thickness), but it is sensitive to smelting impurities (phosphorus and sulphur ≤ 0.030%) and white point defects need to be controlled.
55NiCrMoV6 tool steel (German DIN, composition approximates 1.2713)
Composition and property correlation: X55NiCrV6 tool steel is a high-nickel-chromium-vanadium alloy steel, with a typical composition of carbon (0.50%-0.60%), nickel, chromium (0.60%-0.80%), vanadium (0.07%) 0.07%-0.12%) and vanadium (0.07%-0.12%), differing from 1.2713 by the absence of molybdenum.
Process characteristics: oil quenching at 830-870°C, hardness gradient after tempering similar to 1.2713 (tempered hardness 47-56 HRC at 160-300°C). The need to improve purity by electroslag remelting (ESR) and the low heat treatment distortion rate make it suitable for precision machining.

4.Precautions
Heating process should control the rate of heating to avoid too rapid a rise in temperature leading to workpiece surface oxidation and decarburization. Protective atmosphere heating can be used or placed in the furnace charcoal and other anti-decarburization agent.
When quenching and cooling, choose the appropriate cooling medium and cooling method according to the shape and size of the workpiece to ensure the quenching effect while reducing the risk of deformation and cracking.
