silicon

About 0.10%~0.40%, solid solution enhancement; In addition to the bad effect of FeO on steel quality, it is beneficial.

sulfur

FeS forms a low melting point co-crystal with Fe (melting point 985℃), which causes the steel to become brittle and crack during hot working at 1000~1250℃, "hot brittle". Harmful.

phosphorus

The strength and hardness increase, but the plasticity and toughness reduce, "cold and brittle". Harmful.
