Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the P295GH grade steel material project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of p295gh grade steel material customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

p295gh grade steel material and so on medium and heavy plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on fields. The surface quality problems of medium and heavy plates not only affect the appearance of the products, but also reduce the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate. Therefore, the medium and heavy plates manufacturers and users attach great importance to it. The surface quality of medium and heavy plate mainly refers to the surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plates.

The hot rolling method is to heat the p295gh grade steel material steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of p295gh grade steel material rolling process is usually called semi-finished product production, also called blank production.

Heat treatment specification and microstructure of p295gh grade steel material, 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling.
