1: Q460 Steel Introduction

Q460 steel is a kind of high-strength low alloy steel with a yield strength of 460 MPa. This means that when the external force is withdrawn, the steel can only maintain the shape of the force but cannot return to its original shape, and this strength is greater than that of normal steel.Q460 steel plate has an appropriate increase in micro-alloying elements on the basis of ensuring the low carbon equivalent. This design increases the strength of the steel while having less impact on the weldability of the steel, because the increase in carbon equivalent is very small. In addition, Q460 steel has good weldability and is suitable for a variety of welded structural parts.

4: Q460 Steel Mechanical Properties

The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.

10: Packing& Delivery

For the delivery, we will choose LCL, FCL and Bulk carrier according to order quantity. Usually if the quantity is less than 10tons, we will recommend LCL. If the quantity is more than 100tons, we will recommend bulk carrier. Usually FCL will be the most common for delivery.

In order to better ensure the safety of your goods, we will provide professional, environmentally friendly, convenient and efficient packaging services. Such as pallet, wooden box, package with woven bag etc.

11: Q460 Steel Heat Treatment

Normalizing

Q460 steel plate is heated to a temperature range of 900-950°C, held for a period of time (typically 1 hour per 25 mm plate thickness), and then cooled rapidly, either by water or oil. Normalizing can change the organizational structure of the steel and improve its strength and hardness.

Tempering

Heat Q460 steel to a temperature range of 750-780°C, hold for a period of time, and then cool rapidly. Tempering can reduce the residual stresses within the steel, improve toughness, and make the organizational structure more uniform.

Quenching

Heat the Q460 steel to an appropriate temperature (e.g. 900-950°C), hold for a period of time and then cool rapidly. Quenching can significantly improve the hardness and wear resistance of the steel.

Tempering

The process of quenching followed by tempering is usually used to further improve the overall performance of the steel.

12: Q460 Steel Application

Q460 steel is mainly used for large welded structural parts, including large ships, bridges, power station equipment, medium and high-pressure boilers, high-pressure containers, rolling stock, lifting machinery, mining machinery and so on.

13: Delivery Condition

For hot forged or hot rolled bar, usually the delivery condition is hot forged or rolled, annealed or QT, black surface or rough turned.
For hot forged plate, usually the delivery condition is hot forged, annealed or QT, milled surface.
For hot rolled plate, usually the delivery condition is hot rolled, annealed or QT, black surface.
