DIN 1.2363(X100CrMoV5) Cold Worked Mold Steel
The usage is as follows:
1. Tool and die making: 1.2363 steel is often used to make cutting tools, molds, and dies due to its high hardness and wear resistance.
2. Industrial knives and blades: The toughness and edge retention of 1.2363 steel make it ideal for manufacturing industrial knives and blades used in cutting and shearing applications.
3. Machine components: 1.2363 steel is also used in the production of various machine components such as gears, shafts, and bearings due to its good dimensional stability and strength.
4. Automotive industry: Some automotive components, such as crankshafts and transmission parts, are made from 1.2363 steel due to its high strength and durability.

DIN 1.2363(X100CrMoV5) Cold Worked Mold Steel
1: AISI A2 steel introduction
AISI A2 tool steel is one of 'A' group cold works steel in ASTM A681 standard. A2 Tool Steel is a versatile, air hardening chromium alloy tool steel that replaces O1 tool steel when safer hardening, less distortion and increased wear resistance are required. AISI type A2 steel is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel.

4: AISI A2 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

6: Heat Treatment
Stress relieving
After heavy grinding or machine it is advisable to stress relieve tool steel A2 to reduce the danger of cracking or distortion during subsequent heat treatments. Heat slowly to 670-700°C, soak for a minimum of two hours per 25mm of section then cool down in the furnace.
Annealing
To prevent decarburization use a controlled atmosphere furnace or pack in a sealed container using some inert material. To anneal A2 tool steel for lowest hardness, heat slowly to 899°C(1650°F) and hold at this temperature for about two hours per inch of greatest cross-section. Cool steel A2 at a rate of 20°F (10°C) per hour to 650°C (1200°F) and reheat to 732°C (1350°F); hold 3 hours per inch of greatest cross-section; furnace cool at 20 degrees per hour to 593°C (1100°F); then furnace-cool to 482°C (900°F) and air-cool.
Hardening
Preheating temperature: 1200–1380°F (650–750°C). Austenitizing temperature: 1700 –1780°F (925–970°C) but usually 1720–1760°F (940–960°C).
Tempering
Choose the tempering temperature according to the hardness required by reference to the tempering graph.
Heat uniformly and thoroughly to the desired temperature and hold for 25 minutes per cm of thickness. Tool steel A2 can be double tempering, after intermediate cooling to room temperature. Temper at 200°C for a balance of hardness and strength or 350°C where strength is more important than hardness. A minimum holding time of 2 hours per inch of greatest cross-section should be used.
Quenching
Martempering bath or fluidized bed at 360–430°F (180–220°C) or 840–1020°F (450–550°C) then cool in air
Circulating air or atmosphere
Vacuum furnace with overpressure of gas at cooling
Oil (only for small and uncomplicated tools)
