China supply steel price of SPA-H factory impact toughness

Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.

The main varieties of hot-rolled steel plates are ordinary carbon steel, low alloy steel, container plate, weathering steel, pipeline steel, hot-rolled steel strip for automobiles, ship plate, gas cylinder steel, boiler and pressure vessel plate, steel price of SPA-H factory. Hot-rolled steel strips are processed into different finishing lines to become steel plate, flat coil and slit steel strip products. Our hot-rolled steel plates are widely used in automobiles, machinery, ships, bridges, construction, pressure vessels, pipeline transportation, automotive industry.

Q550C steel belongs to low alloy high strength steel. Chemical composition of Q550C steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 0.80, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. Mechanical properties of Q550C steel: yield strength ≥ 550 MPa, tensile strength 600-780 MPa, elongation after fracture ≥ 16%, impact energy ≥ 55J. steel price of SPA-H factory, Q550C steel is mainly used for manufacturing various large-scale engineering structural components and construction machinery. Due to its high strength, Q550C steel can meet the requirements of large-scale and lightweight construction machinery.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the steel price of SPA-H factory steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent steel price of SPA-H factory products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the steel price of SPA-H factory technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.

We are known as steel price of SPA-H factory leading manufacturers, suppliers and exporters in the market all over the world. We engage in providing a wide range of plates which are accurately mass produced by using the best quality of parts which gives maximum durability and dependability. The most important thing to know as a potential customer of IRON&STEEL is that we steel price of SPA-H factory stock, processing service, and distribute all of the popular grades of carbon steel plate, alloy steel, shipbuilding steel and boiler steel.
