Here is a detailed introduction to EN 10025 - 6 S890QL high - strength low - alloy steel plate:

Basic Information1

Steel Grade Representation: "S" indicates structural steel, "890" represents the minimum yield strength of 890 MPa for steel with a thickness less than 50 mm, "Q" indicates the delivery condition is quenching + tempering, and "L" indicates that the minimum impact energy is specified at a temperature not lower than - 40 °C. Its steel number is 1.8983, and it is classified as a special alloy steel according to EN 10020.

Execution Standard: EN 10025 - 6.

Delivery Status: It is delivered in the quenched and tempered heat - treatment state. Additional requirements such as flaw - detection standards, flaw - detection levels, and control requirements for alloy element composition can be added according to the buyer's requirements, but they need to be communicated between the buyer and the manufacturer and specified in the contract.
