The higher the percentage of carbon in the steel, the more the hardness, strength and elasticity of the metal increase.
Aluminum is an active oxidizing agent, its presence in the composition of steel increases the properties of strength, hardness and heat resistance.
The content of copper in steel affects the improvement of corrosion resistance properties.
The presence of chromium in steel increases the properties of strength and heat resistance, increases the anti-corrosion properties of the metal. The high chromium content makes the steel stainless. The presence of chromium in the chemical composition reduces the viscosity of the metal.
The content of tungsten affects the decrease in weldability, increases hardness and red hardness, improves the anti-corrosion properties of steel.
The presence of nickel increases the strength of the metal, but reduces its thermal conductivity. A large amount of nickel in steel affects the loss of magnetic properties.
Manganese is added to steel to reduce the negative effect of sulfur and oxygen in the composition, which increases the strength and hardness of the metal. However, the manganese content reduces its impact resistance.
The presence of cobalt in the chemical composition of steel affects the increase in impact and heat resistance. The cobalt content makes the metal magnetic.
The titanium content increases the anti-corrosion properties of steel, and also positively affects the density and ductility of the metal.
Silicon is an active oxidizing agent, therefore, with a high content in steel, it makes it brittle.
The content of niobium - increases the anti-corrosion properties of steel, positively affects the acid resistance of the metal.
Vanadium increases the resistance to overheating of steel, and also increases strength and density.
The presence of molybdenum in the chemical composition increases impact resistance, anti-corrosion properties, and strength. Makes steel heat resistant, and therefore reduces weldability.
Harmful impurities in steel include sulfur and phosphorus . The sulfur content in the chemical composition of steel more than 0.045% makes it red-brittle, and phosphorus in an amount of more than 0.045% - cold-brittle.
