Low carbon steel p235gh material equivalent application

Pageviews:

Medium and thick plates P235GH material equivalent are mostly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction, etc. Medium and thick plates can also be used to make all kinds of containers, furnace shells, furnace plates, automobile static steel plates and so on. Among them, shipbuilding steel plate is used to make marine and inland ships. The shipbuilding steel plate p235gh material equivalent is required to have high strength, plasticity, toughness, good cold bending performance, welding performance and corrosion resistance.

Our company is a large p235gh material equivalent steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special p235gh material equivalent steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.

The main applications of normalizing are as follows:① For low carbon steel, p235gh material equivalent. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.

The basic phases of p235gh material equivalent, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.

Both parties shall confirm the p235gh material equivalent material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the p235gh material equivalent steel plant.
