What is the effect of carbon, sulfur and phosphorus on the properties of steel?

The effects of chemical elements on the properties of steel:1. Carbon (C): The carbon content in steel increases, the yield point and tensile strength increase, but the plasticity and impact strength decrease. When the carbon content exceeds 0.23%, the weldability of steel deteriorates. Therefore, the carbon content in low alloy structural steel used for welding generally does not exceed 0.20%. High carbon content also reduces the atmospheric resistance of steel...

A brief analysis of the chemical composition of affect the properties of the steel? Briefly analyze how the chemical composition of steel affects the properties of steel.

Carbon: It exists in all steels and is the most important hardening element. It helps to increase the strength of the steel. We usually want the steel of the cutter grade to have more than 0.6% carbon, which also becomes high carbon steel.
Phosphorus is one of the harmful impurities in steel. When used at room temperature or lower temperature, steels containing more phosphorus are prone to brittle fracture, which is called "cold brittleness ". The higher the carbon content in steel, the more serious the brittleness caused by phosphorus. Generally, it is specified that the phosphorus content in ordinary steel is not more than 0.045%, and the high-quality steel is required to contain less phosphorus.
Sulphur is seriously segregated in the steel and deteriorates the quality of the steel.
Chromium: Increases wear resistance, hardness, and most importantly corrosion resistance, with more than 13% considered stainless steel.
Manganese: An important element that contributes to texture, firmness, strength, and abrasion resistance.
Molybdenum: Carbonizing agent that prevents steel from becoming brittle and maintains its strength at high temperatures.
Nickel: Maintain strength, corrosion resistance, and toughness.
Silicon: Helps to increase strength. Like manganese, silicon is used to maintain the strength of steel during production.
Tungsten: Enhanced abrasion resistance. Tungsten is mixed with an appropriate proportion of chromium or manganese for high speed steel.
Vanadium: Increased wear resistance and ductility. A carbide of vanadium is used in the manufacture of striped steels. Vanadium is present in many steels.
