(1) As special quality steel products, wire rod with P content less than 0.03% and S content less than 0.035% are available.
(2) Unless otherwise specified, these are manufactured as fine grained steels of Si content 0.15∼0.30%
(3) Carbon steels other Chan boron steels listed above can also be manufactured with boron added to enhance hardenability. In either case, the boron content is 0.0005∼0.003%
(4) "H" steels with specified hardenability are also available.
