GB-T1591 Q460E High Strength Structural Steel Plates

GB-T1591 Q460E High Strength Structural Steel Plates

Q460E steel plate is a kind of low alloy high strength steel plate. The yield strength of this material is relatively high, and the plastic deformation is possible only when the stress strength of the steel reaches 460 MPa, and the shape of the stress will be maintained after the withdrawal of the external force.The content of micro-alloying elements in Q460 is increased, so the welding performance of this material is relatively good, and the strength is also higher. Which Q is expressed in the yield strength, 460 is expressed in the yield strength of the value, that is, 460 MPa, E on behalf of the quality level, that is, the E level, the quality level is divided into C, D, E three levels.Q460D, Q460E.

Q460E is composed of 'Q' expressed by the yield; 460 indicates that the yield value of the steel plate is 460MPa; 'E' expresses the steel plate for the impact test for -40 ° (commonly used grades are C, D, E, F). The executive standard is: GB/T 1591.

Q460E high strength low alloy steel sheet default hot rolled delivery below 40mm;

Q460E hsla structural steel above 40mm is delivered normalized by default.

According to the different needs can also do normalized + tempered or normalized + quenched and a probe two probe three probe, etc., different delivery states will change the composition of the steel plate performance indicators and uses, so the choice of steel plate delivery state technical requirements and use of the situation to do a good job of harmonizing standards.

Steel plate thickness direction performance requirements: Z15, Z25, Z35.

Steel plate flaw detection requirements: a probe, two probe, three probe.

Q460E nlow alloy steel plates ot only has a very high strength and also has a certain toughness, wear resistance, fatigue resistance, impact resistance, corrosion resistance and welding easy processing properties, most applications in the machinery manufacturing industry, such as; mining machinery, coal mining machinery, bridge equipment, steam turbines, pressure elements, steel structure engineering, etc. Usage is very common.

We have sufficient inventory and can package and ship in the shortest time. If you have any needs for GB-T1591 Q460E High Strength Structural Steel Plates products, please contact me.
