The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, A709 grade HPS70W bridge steel plate steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and A709 grade HPS70W bridge steel plate carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.
Q420q steel material is a kind of structural steel plate for bridges, the grades are Q420qD, Q420qE, Q420qF.Q420q steel chemical composition: C: ≤0.11, Si: ≤0.55, Mn: 1.0-1.7, Nb: 0.01-0.09, V: 0.01-0.08, Ti: 0.006-0.03, Cr: ≤0.50, Ni: ≤0.30, Cu: ≤0.30, N : ≤0.008, Al: 0.01-0.045.Steel delivery status: delivered in the thermomechanical rolling state, and the steel plate should be trimmed for delivery.
The alloy steel plate has higher oxidation resistance and corrosion resistance, and is more suitable for use in acid and alkali environments. The surface of alloy steel plate will not be oxidized and corroded, maintaining the brightness of the steel plate. The alloy steel plate also has high material strength, its pressure bearing performance is very outstanding. It has high plasticity under the condition of long-lasting stretching. The A709 grade HPS70W bridge steel plate, alloy steel plate is not prone to fracture, and it is more durable.
The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, A709 grade HPS70W bridge steel plate.
Structural steel is a category of steel construction material that is produced with a particular cross section or shape, and some specified values of strength and chemical composition. A709 grade HPS70W bridge steel plate, Structural steel plates are normally supplied in the as-rolled condition. Our structural steel plate are supplied with thickness range 3mm to 350mm. The plates may be ordered normalized or stress relieved, or both. steel plates shall be normalized. steel plates and sheets shall be quenched and tempered.
We have a good inventory system because of which the alloy steel plates and structural steel sheets are supplied and delivered to our customers on time. Our alloy steel plate is significantly affordable than austenitic A709 grade HPS70W bridge steel plate stainless steel which helps to reduce maintenance and full life costs – as well as improved safety over standard boilerplate. Contact us today to request a quotation or email us with your complete specification, we are happy to help you!
