Diversity in the steel industry often intimidates people who, for one reason or another, need to select and purchase a particular grade of steel for specific needs. An unprepared person with a high degree of probability will get lost in this diversity and will not choose anything in the end. This problem is solved through a long and methodical study of the topic, understanding its very essence, numerous discussions and much more. However, there is a way to take a short cut.

ВWe have tried to collect for you the most important and useful information regarding steel 09G2S. Reading will not take much time, and the knowledge gained will help you choose the right material.

Steel 09G2S - transcript

In order to understand what properties an alloy has, it is not at all necessary to study its molecular structure using sophisticated laboratory instruments. Often, to get a general idea of the propertiesmetal and its purpose, it is enough to properly decipher the designation of the steel grade. 09G2S in this case is decrypted according to the following algorithm:

• The numerical value 09 corresponds to the carbon content in the composition of the alloy. Often, the maximum possible value is indicated, which means that the percentage suspension of this element per unit mass of steel does not exceed the threshold of 0.9%.
• The letter designation “G”, according to the Soviet GOST system, indicates the content of such an alloying element as manganese.
• The next number "2" indicates the maximum percentage of the content of this element, equal to two percent of the total mass.
• The letter “C” in the Soviet GOST system corresponds to silicon. Given that there is no further numerical value, its content is, on average, less than one percent.

Steel composition

In order to study the properties of this alloy in more detail, it is necessary to know it a little better. To do this, there are special industrial regulatory documents of the state standard, in other words - GOSTs. Steel 09G2S, according to its quality standard, has the following composition:

• Carbon (up to 0.12%) is one of the most important additives that gives steel the necessary hardness and strength, but, as a result, brittleness.
• Silicon (0.65%) - an element that positively affects the heat resistance of steel.
• Manganese (1.5%) - an additive that significantly increases the strength of steel and its hardenability.
• Nickel (up to 0.3%). This element in the composition correspondsfor increasing the ductility of steel without diminishing its strength properties.
• Sulfur (up to 0.04%) is a harmful impurity that worsens the properties of steel, but its percentage is insignificant, which means that the effect on the material is not critical.
• Phosphorus (up to 0.035%) - a material similar to sulfur, has a much more significant deteriorating effect, so its content is regulated especially carefully.
• Chromium (up to 0.3%) increases the resistance of steel to oxidation and rusting.
• Nitrogen (up to 0.008%) is an inevitable impurity resulting from the steelmaking process.
• Copper (up to 0.3%) has a positive effect on steel ductility.
• Arsenic (up to 0.08%) is another harmful impurity that provokes the appearance of internal defects, but its content is limited.

Characteristics of steel 09G2S

The following is extremely noticeable: there are quite a lot of impurities in the alloy. Ten types of alloying elements is a considerable number, but only manganese can boast of a truly significant content. Based on this, it can be confidently stated that 09G2S steel has heat-resistant properties, and the remaining impurities only complement and improve the steel structure, which has a positive effect on its other physical properties. It remains plastic, easily amenable to physical processing, including turning. Steel, among other things, has a very homogeneous structure, which allows it to withstand high loads and pressures.

Analogues

Comparatively similar steel grades come across everywhere. This is due to their constant demand. It is often required to purchase a part made of steel 09G2S. Therefore, it would be nice to have at hand a list of the names of its foreign counterparts:

• Germany - 13Mn6.
• Japan - SB49.
• China - 12Mn.
• Russia - 09G2 or 10G2S.

In general, this steel grade is very common in the industry, so even such a small list is more than enough to find the steel grade you need in any corner of the planet.
