Q390C ANGLE STEEL

Xinsteel stockholder thousands tons different sizes of Q390C steel angles,Q390C angle steels,Q390C equal angle steel,GB/T706 Q390C un-equal angle steels and Q390C inverted angle steels. High strength low alloy structural steel angle Q390C owned the minimum yield point above 390 Mpa,and tensile strength shall be within 490-650 Mpa.Normlised Q390C is mainly for heavy steel angles for improve the steel property when rolling.

Technical Requirements & Additional Services:
♦ Low temperature impacting test
