Product Description

JIS SKD7 DIN 32crmov3-3 BS BH10 Hot Rolled Forged Steel Plate
JIS SKD7 DIN 32crmov3-3 BS Bh10 Hot Rolled Forged Steel Plate
1: ASTM H10 steel introduction
     H10 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.
H10 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.

     H10 hot works 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.

Application  ASTM H10 tool steel are suitable for highly stressed hot work tools, mainly for the processing of heavy alloys, such as: Extrusion Industry: Dies, Inner Liners, Stems, Pressure Pads, Mandrels for Extrusion, Forging Industry: Forming Dies, Press Dies, Pressing Mandrels, Die Casting Industry: dies for die-casting, die inserts, hot shear blades, moulds for processing brass and light metal

 

6.Heat Treatment

Annealing 

     Heating slowly and uniformly to 750~790ºC, furnace cooling to
600ºC at a rate 10~20ºC/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

     H10 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

    

 

7: Delivery condition
     For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed, rough turned.
     For hot forged plate, usually the delivery condition is hot forged, annealed, milled surface.

     For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
