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.
