High strength 16mo3 equivalent low alloy

The toughness index of Q345B steel should be tested by impact test at 20 ℃. Although the strength of Q345B steel and Q345A steel are the same, the S / P control of Q345B steel is more strict, and the ambient temperatures of 16Mo3 equivalent, Q345B steel and Q345A steel are different. The cold impact test refers to the impact test at a certain temperature to obtain the energy consumed by punching the specimen. The more energy consumed, the higher the toughness of the material. Q345A is not subject to impact test. So Q345B steel is better than Q345A steel.

In recent years, in line with the development trend of iron and 16mo3 equivalent steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which 16mo3 equivalent are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel 16mo3 equivalent. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect. The CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting of medium and thick plates. Compared with other similar thermal cutting methods, the CNC flame cutting machine has the characteristics of high cutting quality, good cutting surface perpendicularity, and large cutting thickness.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the 16mo3 equivalent plate should be derusted before cutting.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
