AISI H13 H-13(1.2344,X40CrMoV5-1,SKD61,DC53)Forged Forging Steel tunnel boring machine TBM Discs CUTTING Cutter Rings

We are professionals
AISI H13 H-13(1.2344,X40CrMoV5-1,SKD61,DC53)Forged Forging Steel tunnel boring machine TBM Discs CUTTING Cutter Rings factory from china

Our cutter rings are produced from standard steel, heavy duty steel and H13 tool steel with standard profile or hard faced profile in different hardness to accommodate various geological conditions such as sandstone, conglomerates, limestone, marble, quartzite, basalt, diorite and granite.
They are apply to the sand limestone, dolomite, kimestone, condensate, such as granite from soft rock to hard rock, all rocks. And they are suitable for Herrenknecht, Mitsubishi, Wirth, Komatsu, Robbins tunnel boring machines, we also can produce according to customers drawings or samples
It could be devided into single disc cutter , double disc cutter , multiple disc cutter . Its outer cutter rings could be devided into standard cutter ring , wide disc cutter ring , heavy duty cutter ring , surface overlaying welding cutter ring , cutter ring with carbide button etc .

Its cutter rings material could be choosed according to tunnel working condition
TBM cutter rings must be highly wear resistant and robust because they serve as the key excavation component.

Standard cutter rings are forged with alloy tool steel and heat-treated to HRC56-58 with an ideal balance between hardness and toughness, making them suitable for soft ground to mixed ground.
Heavy duty cutter rings are forged with alloy tool steel and particularly heat-treated to HRC57-59 with an ideal balance between hardness and toughness to avoid curling and fracturing, so they are suitable for hard rock and abrasive rock.
TCI cutter rings are inserted with tungsten carbide tips and suitable for abrasive but not hard ground. The undulating nature of the TCI would help the cutter to rotate in the low strength but abrasive rock, and avoid flat spotting.
The cutter rings are manufactured with ideal profile and tip width, usually 13mm to 25mm depending on ground conditions, in order to achieve high excavating efficiency and long lifetime.
Our TBM cutter rings can be interchanged completely with Herrenknecht, Palmieri, Robbins, and Wirth cutter rings.

H13 Tool Steel is a high hot-wear resistance and great strength, warm conductivity air hardening and invulnerability to hot cracking. It has a great resistance to abrasion at each low and high temperature due to presence of high Vanadium. The high level of toughness and ductility made it a popular material for die casting in the cold heading field.
H13 have Uniform and high level of machinability and polish ability. Good high-temperature strength and resistance to thermal fatigue, glorious through-hardening properties are making H13 steel very limited distortion during hardening. H13 tool steel is extensively used for aluminum, magnesium and zinc die casting. It has an outstanding impact on strength to resist cleavage cracking, size changing character, easy to machine and can be water cooled in service.
H13 contains 5% chromium die steel, that gives a wide range of application in hot work and cold word. Hot work applications are in shear knives, dummy block extrusion. Cold works are used in inserting, punching and heading of die blocks. It is observed that, Cold work applications are increased by using H13. Excellent toughness is the best quality of H13.

H13 Steel Properties

High hot-wear resistance and hot tensile strength as well as good toughness, thermal conductivity and insusceptibility to hotcracking. Can be water-cooled to a limited extent.
