Steel 65G, which is actively used for the manufacture of knives, is a material that is based on an alloy of elements such as carbon and iron. It is important to note here that the proportions of these two substances can differ significantly, depending on what qualities are required from the steel, and also why in the future it will be used.
Product General Information
A significant item included in the specification of 65G steel is low cost. Due to this, all products from this alloy are in great demand.
The material itself belongs to the group of spring-spring steels. The substance is best suited to operations such as burnishing and blackening. Due to the special qualities of steel, the material is most often used for the production of various throwing knives, rarely, but, nevertheless, it is used as the basis for the assembly of cutting-type knives. A rare use of the alloy is due to the fact that it quickly becomes covered with rust and oxidizes.
It is worth noting that hardening of 65G steel is one of the main procedures, since the alloy is practically not afraid of high temperatures. The only drawback that can occur with too much overheating is a decrease in toughness.
Key Product Benefits
Among the main advantages of 65G steel are the following:
- Huge margin of safety. This suggests that even with high mechanical loads, the knives will not break, deform.
- High resistance to shock and deforming loads. It is because of this quality that the material is more often used to create throwing knives or swords, somewhat less often for medical-type scalpels.
- Sharpening the material is quite simple.
- Tear resistance is also high.
As for the marking of steel, the number 65 indicates the percentage of a substance such as carbon, in hundredths of a percent, that is, 0.65%. The letter "G" indicates that manganese has become the main alloying substance.
Negative alloy qualities
It is known that 65G steel has a number of negative qualities that create certain restrictions on the use of the alloy.
- One of the most noticeable disadvantages is the strong susceptibility to corrosion due to the fact that steel belongs to the carbon-containing group.
- Despite the fact that the steel of this brand is sharpened quite simply, it is also easy and loses this sharpening. For this reason, you have to constantly monitor the sharpness of the cutting edge and sharpen as necessary.
- Quite a lot of restrictions are in the scope.
It is worth noting here that both advantages and disadvantages are relative properties. To attribute them to absolutely any product from this alloy is impractical. This is easily explained by the fact that each steel producer uses production technology with some changes. Sometimes the composition is not much different, and sometimes the difference is almost everything. Naturally, the products will also be different in this case.
Features of the composition
Certain properties of steel 65G have led to the fact that it is completely unsuitable for such a procedure as welding. However, even despite this, the scope remains wide enough if you do not take into account the use of cold steel. Such an alloy can successfully produce parts such as springs, springs, metal structures, various components, etc. Steel is used in the assembly of trucks as a spring for the rear axle. In order to avoid a defect such as rust for as long as possible, it is necessary to store products only in a dry place, and also periodically cover them with an oil composition.
It is worth noting that there is a document that regulates the basic qualities of this product. Steel 65G is produced in accordance with GOST 14959-2016. This document applies only to steel made either by hot rolled or forged.
It is worth noting that the absence of a large number of elements for alloying the composition makes it fairly cheap. In addition, hardening of 65G steel improves parameters such as wear resistance, high impact strength and some others. Quenching occurs at a temperature of 800-830 degrees Celsius, followed by tempering at a temperature of 160-200 degrees Celsius.
