Is the inner six angle spanner bent with six angles carbon steel?
The inner six angle spanner is made of six edges of steel bending, and can also be made of round bar material and six ends milling;Good, six angle wrench, hardness of 45-50, with 45 steel bending and then quenching, attention should be paid to the hardness of quenching.
Most of our factory is using their own six angle wrench, material 45 steel, round bar material, milling six sides, bending quenching HRC45 - 50, very easy to use. Later to buy a set of outside market, bluing nicely, you encounter a situation I have encountered, but if I buy good quenching as well, of course, also have the opposite, overquenching, easy to break. Now the domestic market to buy things to dragons and fishes jumbled together, have some experience, buy six square wrench, with a small file, and a slip, hardness enough to be moved, and the hardness is not enough, do not buy.
Generally, the process of making the six corners hand is divided into the following steps:1, 45#, 40Cr and 50# rolled into hexagonal wire.2, blanking, 90 degrees right angle forming.3, quenching and tempering, hardness requirements of HRC43-50.4, surface treatment, oxidation, leather, black, electroplating and so on.
On the market, the sale of genuine products in the six corners of the hand are hot stamping process, only a very small part of shoddy products, poor workmanship, in order to save costs, is a molding.
