Transmission Irons

What are Transmission Irons?

transmission iron, iron and steel industryIt is a special quality product. in a general frameworktransmission ironIf we look at the answer to the question of what is it, cold drawn, round cross-section and1008 SAEor EN S235JrWe can say that they are quality steels. When we look at their features, we see how reasonable they are for various procedures. For example, the welding procedure, which is an important feature,from suitabilityLet's talk. Having a low carbon value, it becomes very suitable for welding application thanks to these features. On the other handmachiningalso suitableThey become materials.Both CNClathescan be processed simplyThey provide both ease of use and efficiency. Steels that are formed by extruding at room temperaturetransmission steelorcold drawing steelis called.cold drawingwith the processmaterial without the need for heat treatment. Yield Strengthand pull strengthIt is aimed to increase the durability. 

-The products have low carbon values. Thanks to these features, their welding capabilities are quite high.

-One of the most important features is that they are economical compared to other types of steel.

-with transmission shaftsThe fact that operations or assembly can be done easily makes the spindle preferred in different sectors.

-transmission shaftsIt is preferred for the operations to be carried out due to the absence of hardness in chip removal during use.

-The high surface quality of the shafts and a smooth shaping are among the features that increase their preferability.

-transmission shaftsOne of the most important features of choosingare the mechanical properties. These properties are easy shrinkage, hardness, impact, shrinkage and elongation.

-transmission shaftsThey shrink easily and are extremely resistant to external impacts. They are also resistant to conditions such as shrinkage or elongation. It can ensure that transactions are carried out without breaking in pulling situations.

-The heat holding capacities and expansion coefficients of our shafts are also high.

Usage Areas

If we talk briefly about the usage areas, we can list them as follows; It is used in special areas such as construction, automotive, machine production, white goods sector and the same, as well as in the defense industry.Usage areas of transmission steelswhile they can be sorted in this way, it is not possible to rank the products they are used in. Countless products,transmission ironcontains.

cold drawing techniqueIt is subjected to a second process to be brought into different shapes such as round, square or hexagonal. We can easily call this process “tightening”. If the customer has expectations such as exacting tolerance and high surface quality, this is what we have mentioned.cold drawing techniquewill give the best result. In short,cold drawingThe product obtained with the technique of precision measurement tolerance, has a superior surface quality, an increase in both yield and tensile stress of the product occurs, and an increase in hardness is observed while its continuity decreases. Ultimately, as a product with superior featurestransmission ironis encountered.
