S960Q steel is a high yield strength structural steel in the quenched and tempered delivery state.
The symbol S represents structural steel, and 960 represents the minimum yield strength below a thickness of 50mm.
Q indicates the quenching and tempering delivery status.
S960q steel plate can withstand -20℃ temperature impact and the energy is 30J.
Regarding the weldability of S960Q steels General requirements for arc welding of specified steels shall be given in accordance with EN 1011-2.
