Note:
(1): In order to improve the properties of steel, other trace alloying elements other than the above table can be added, and the data comes from the network and is for reference only.
(2): The allowable deviation of the chemical composition of the finished steel plate shall comply with the provisions
of GB/T222 Q295HR steel plate delivery status: delivery in normalized state, when the user requires and indicates in the contract, the steel plate that needs to be heat processed after delivery can be delivered in a non-heat treatment state. It can also be added according to the needs of the requirements of flaw detection standards, flaw detection grades, classification society certification requirements, Z-direction performance requirements, adding special alloy elements, etc., but need to be communicated by both suppliers and demanders, and indicated in the contract. Q295HR container plate production process:
electric furnace smelting→LF/VD furnace refining→ ingot → cleaning→ ingot heating→ rolling plate → flaw detection→ normalizing → steel plate grinding→ cutting and sampling→ performance inspection → warehousing
