COMMENTS OF THE MASTER:
"Dear customers, we draw your attention to the fact that all products are made purely by hand and have a unique individual character. That is, the appearance of the product (shade and structure of wood, depth of metal etching, leather texture, etc.) may differ slightly from the photo, but in general the product will be as close as possible to the photo in the product card. Thank you for your understanding!
"By the way, you can order any inscription of your choice both on the leather cover and on the ax log itself to make the ax unique! All this can be discussed during the order! Call or write - always happy to help!
Drawings are applied to the blade by the method of etching in a chlorine gland. There is also wood carving, everything is done by hand, without lasers and CNC!"

Deciphering the U8 steel grade: the letter U indicates that we have a tool-quality unalloyed steel in front of us, which contains carbon in an average amount of 0.8%.
U8 steel tool and its heat treatment: locksmith hammers are made of U7 and U8 steels. The battlements and the tail are subject to hardening. Heating is best done in a salt or lead bath. When heating the hammer in a chamber furnace, the hammer is first hardened, and then the tail, after which it is alternately cooled until the middle part is completely darkened. For final cooling, the hammer is transferred to oil. Bake at 260-340 ° for 30-40 minutes. Hardness R c = 49-56. The hardness is checked on the RV device.
U8 or U7 steel is used for the manufacture of pneumatic tools. The working tail part is subjected to hardening. You should avoid heating the pneumatic tool completely, so it is best to heat it in salt or lead baths. The working part is hardened in water with transfer to oil, and the tail part in oil. After that, the tool is tempered depending on the required hardness of the working part, namely: chisels, cross chisels, punches, embossing and notches are tempered at 240-270 ° with a holding time of 30-40 minutes. Required hardness R c = 56-59.
Crimping, support, fighting and knocking out are released at 270-300 ° for 30-40 minutes. Required hardness R c = 53-56. Determine the hardness with a calibrated file. There are rare cases when a pneumatic tool breaks during operation at the point of transition from a smaller diameter to a larger one, and the fracture structure is very fine-grained to a depth of 5-8 mm around the circumference, and coarse-grained deeper. The main cause of breakdowns is insufficient cleanliness of the surface at transition points (risks, scratches, etc.).
Machine tool bits are made of U8, U9, 65X steels. The place of transition from the thin part of the bit to the thick part, as well as the walls of the hole in the hollow bit, should be hardened to a small hardness. If this is not observed, the bit may bend or break during operation. A slight transition hardness is achieved by intermittent water quenching for solid carbon steel bits, or full quenching followed by salt bath quenching to gray runout for all other bits. The tail part is not hardened. Solid chisels are fired at a temperature of 260-280 °, and hollow ones at 320-360 °; keep for 20-30 minutes. The required hardness for false bits is R c = 56-58, and for hollow bits R c = 50-52.
Carpentry and carpentry chisels and chisels are made from the same steels. Heat for hardening is produced in furnaces-baths with a length of 60-80 mm. When heating chamber furnaces, the tool is soaked for a length of 60-80 mm. The tail part is not hardened. Leave at a temperature of 250-300° for 20-40 minutes. Required hardness R c = 53-58.
Combined pliers and nippers are made of U7 and U8 steels. They are subjected to heat treatment in assembled form with open jaws, only the working part is cut - in nippers, the length of the sponge is 8-10 mm, and in the combined pliers, the length of the sponge is included, including the slots in the hinge. Cool in oil or kerosene with vigorous stirring. The leave is produced at a normal temperature of 220-300° for 30-40 minutes. Hardness R c = 52-60. The hardness is controlled on the RV device or with a calibrated file, as well as by biting off a steel wire with a diameter of 2 mm.
Stamps are made of the above-mentioned steels, hardened with subsequent tempering at a temperature of 220-250°. The stem is released by heating in a lead bath until the gray color of the escape. The required hardness of the working part R c =54-58.
