A213 T9 Seamless Round Tubes Alloy Steel

A213 T9 seamless round tubes are chrome molybdenum alloy steel. A213 T9 round tubes alloy steel elements added with a lower percentage i.e. less that 5% is to increase the strength and harden ability and in larger % to accieve special properties like corrosion resistance, high temperature sustainability, high yield and impact results. In the field of piping industry, A213 T9 alloy steel seamless pipes and tubes are heat treated to achive mechanical properties as per the desired alloying element. As for heat treatment, there are normalized quench and tempering, quench and tempering, normalized and hardening. Below is the A213 T9 seamless square amd round tubes chemical composition and mechanical perties.
