p295gh grade steel material properties and features

Pageviews:

The steel such as P295GH grade steel material delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld p295gh grade steel material steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for p295gh grade steel material manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).

When cutting extra thick p295gh grade steel material steel plates, the cutting speed should not be too fast. Many processing and production industries will encounter such problems, that is, in order to speed up the cutting of extra thick steel plates, many details will be ignored in the process of these process operations, so it is easy to produce waste parts, and some plates p295gh grade steel material will crack. So when cutting extra thick steel plates, you must pay attention to the speed, which can not be too fast. Low-speed processing can effectively improve work efficiency.

Delivery status of p295gh grade steel material, SA737 Gr B and SA737 Gr C pressure vessel steel: hot rolled, normalized, tempered.However, when in rolling state, SA737 Gr C pressure vessel steel plate is prone to cracks when subjected to flame cutting, handling and processing. Therefore, SA737 Gr C pressure vessel steel plate can be delivered in rolled state only after the steel mill and the purchaser or processing plant reach an agreement.
