Among the variety of different alloys, there are sometimes those whose purpose and characteristics are surprising to many. You, like many, hearing the word "steel", imagine something solid, solid, unbending. In this case, 60C2A steel will definitely surprise you. In this short article, we will try to convey to the reader the basic, most important information regarding this steel grade, which may be useful to you.
Classification
Since any steel is manufactured on an industrial scale, its production is inevitably standardized, and in the future, the whole process occurs with strict observance of established standards. And first of all, for any steel, its future profile affiliation is established. Thus, GOST 60C2A steel is classified as structural spring-spring.
The next thing you should pay attention to is the composition of the alloying elements of the alloy. It is thanks to them that the resulting steel is endowed with unique properties, which allows it to further occupy a certain niche in production. And the final quality of steel will depend on strict observance of the chemical composition.
For steel 60S2A the following composition is provided:
- 0.6% carbon;
- 1.8% silicon;
- 0.75% manganese;
- 0.3% chromium;
- 0.25% nickel;
- 0.2% copper.
In addition to “useful” impurities, the composition is allowed to contain phosphorus and sulfur up to 0.025% of the total mass.
Characteristics of steel 60S2A
It became immediately clear to those who knew exactly what properties this or that element gives to steel, what characteristics the resulting alloy will have. But beginners should clarify that the presence of silicon, nickel, chromium and manganese in the composition of the steel favorably affects the structure of the alloy, giving it strength, elasticity and ductility. Thus, 60C2A steel has the best strength characteristics, which allows it to undergo high loads, and the increased endurance of the metal, together with increased elasticity, allows it to retain its shape and properties for a long time.
Analogs
You can find similar or maximally similar steel not only in the domestic, but also in the foreign market. The only thing that can confuse you is that in each country, the analogues of steel 602 are presented under different brands.
But given the fact that many of the countries are actively exporting steel abroad, it will be enough for you to know the following:
- United States of America - 9260 or G92600;
- Japan - SUP6 or SUP7;
- China - 60Si2Mn;
- Germany - 60MnSiCr4.
Application
Like any other steel, 602 is used primarily for the manufacture of simple rolling products, whether it be strips, tapes, sheets and wire of various sizes. However, in the future, this steel is used for the manufacture of various kinds of products, which during operation will be constantly exposed to loads. Most often, these are springs, spring rings, torsion shafts and collets, as well as many more products.
But you can stumble upon springs made of this steel. It is these parts of the suspension of wheeled and tracked vehicles that are later used for the manufacture of various tools in artisanal conditions, which already says a lot about the quality of the used spring steel.
