About 0.25%~0.80%. Solid solution strengthening; Remove FeO, reduce the brittleness of steel; Synthesis of MnS with vulcanization can reduce the harmful effects of sulfur. Good for you

manganese

About 0.25%~0.80%. Solid solution strengthening; Remove FeO, reduce the brittleness of steel; Synthesis of MnS with vulcanization can reduce the harmful effects of sulfur. Good for you.

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.

Steel pipes can be divided into two categories according to production methods

2022-08-23

According to the pipe material (that is, steel), steel pipe can be divided into: carbon pipe and alloy pipe, stainless steel pipe, etc.
