1:DIN 1.2365 steel introduction
DIN 1.2365 Tool Steel is one hot works tool steel in ASTM A681 standard, which is for alloy tool steel. The ASTM/AISI classifies chromium hot work tool steels as group H steels, ranging from H10, H11, h12 to H19. AISI H10 Tool Steel is one of chromium hot work tool steel that exhibits excellent resistance to softening at elevated temperature.
DIN 1.2365 Tool Steel is capable of being heat treated to higher hardness than the tungsten hot work steels, and in addition offers greater toughness. H10 tool steel has good thermal fatigue characteristics, and unlike the tungsten hot work steels and H10 hot work tool steels may be safely water cooled in service.
DIN 1.2365 hot work tool steel is recommended for difficult hot work tooling applications such as hot punches, die casting dies, forging dies, hot shear blades, hot gripper dies, and extrusion tooling etc.

6.Heat Treatment
Annealing
Heating slowly and uniformly to 750~790℃, furnace cooling to
600℃ at a rate 10~20℃/hr, further cooling in air. Hardness after annealing: max. 205 HB. Suitable precautions must be taken to prevent excessive carburization or decarburization.
Stress relieving
600 to 650°C (1112 to 1202°F) Slow cooling in furnace; intended to relieve stresses set up by extensive machining, or in complex shapes. After through heating, hold in neutral atmosphere for 1 -2 hours.
Hardening
DIN 1.2365 steel is a very deep hardening steel, and although oil quenching may be used where maximum hardness is required, air hardening is recommended for most applications. The use of salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening spent pitch temperature employed is usually in the range of 982°C -1037°C.
1010 to 1050°C (1850 to 1922°F) Oil, salt bath (500-550°C / 932-1022°F), Holding time after temperature equalization: 15 to 30 minutes. Obtainable hardness: 52 -56 HRC
Tempering
Slow heating to tempering temperature immediately after hardening / time in furnace 1 hour for each 20 mm of work piece thickness but at least 2 hours / cooling in air. It is recommended to temper at least twice. A third tempering cycle for the purpose of stress relieving may be advantageous 1st tempering approx. 30°C (86°F) above maximum secondary hardness. 2nd tempering to desired working hard-ness. The tempering chart shows average tem-pered hardness values. 3rd for stress relieving at a temperature 30 -50°C (86 to 122°F) below highest tempering temperature
