Description
Steel 10G2 is used : for the manufacture of fasteners and other parts operating at temperatures from -70 ° C under pressure; parts of pipeline fittings after hardening and tempering; metal structures; welded transitions of NPP pipelines; seamless hot-deformed cold-resistant pipes for gas lift systems and gas field development.
Note
High-quality structural manganese steel. To obtain high-quality welded joints, additional operations are required: heating to 200−300 °C during welding and heat treatment (annealing) after welding.
Purpose
Steel 10 - carbon, high-quality, structural steel - these definitions indicate its purpose.
Carbon - means unalloyed, with a minimum amount of additives in the composition. The disadvantage of such steels is their susceptibility to corrosion and the undesirability of operation at very high or very low temperatures. The advantages include ease of manufacture, low cost due to the absence of expensive additives in the composition, and high performance characteristics under normal conditions. This is the best steel for mass-use products - structures, pipes, fasteners, fittings, fences, cladding, beams, channels, etc.
Structural - means that the steel is intended for the manufacture of structures (welded and non-welded) and mechanical parts. Such steels are very popular in mechanical engineering and construction. Depending on their characteristics, rigid load-bearing structures, frames, trusses, critical and non-critical parts, fasteners, fittings, etc. are made from them.

Decoding steel 10
The grade of steel indicates its chemical composition, quality and degree of deoxidation. The fewer numbers and letters in the stamp, the simpler the metal composition. One number denotes mild carbon steels, consisting of 98-99% iron.
- The word “steel” means that the brand is of high quality. The quality of steel is determined by the percentage of harmful impurities - phosphorus and sulfur; the lower the percentage, the higher the quality. There are steels of ordinary quality (st), high-quality (steel), high-quality (A) and especially high-quality (SH).
- 10 is the percentage of carbon in hundredths. Steel 10 contains 0.1% carbon. Carbon in significant concentrations changes the properties of the alloy, imparts strength and hardness, but reduces ductility and toughness. Carbon steels are not resistant to corrosion and are not used in aggressive environments, but are well suited for the production of mass-produced products due to their low cost and simplicity of the production process.
- Sp - means the degree of deoxidation - calm. If the degree of deoxidation is not indicated in the marking, as is the case with steel 10, then it is a mild steel. Deoxidation is the process of removing impurities from an alloy, primarily oxygen and nitrogen, in order to reduce the formation of bubbles and gas pockets when the alloy solidifies in the final stages of production. According to the degree of deoxidation, steel can be calm (sp), semi-quiet (ps) and boiling (kp). Boiling water contains the most impurities; its structure is porous and heterogeneous. Calm, maximum purified from impurities and homogeneous. Semi-calm occupies an intermediate position.
The composition of steel is not limited to the elements specified in the grade. The marking lists only those additives that are contained in significant quantities and affect the properties of the alloy.
