Based on the main grade P235GH steel material business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel grade p235gh steel material products are exported to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between grade p235gh steel material, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.

35# steel is a high-quality medium carbon carbon structural steel, with good plasticity and appropriate strength, good process performance, and acceptable welding performance. It grade p235gh steel material is often delivered in normalized and tempered state. 35 # steel is widely used in the manufacture of various forged and hot-pressed parts, cold-drawn and grade p235gh steel material upset forged steel, seamless steel tubes, and parts in machinery manufacturing.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This grade p235gh steel material rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

Chemical composition of Q390C steel plate: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.7, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.10, Al ≤ 0.015. The mechanical properties of Q390C steel plate are: yield strength ≥ 390 MPa, tensile strength 470-620 MPa, elongation after fracture ≥ 18%, impact energy 34J. grade p235gh steel material, Q390C steel plate is used for bridges, vehicles, ships, workshops and other large structural parts, high and medium pressure Petrochemical vessels, boiler tubes, pipes, superheaters, pressure vessels, heavy machinery, etc. application.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
