Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes. We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, A709 Gr HPS70W bridge steel plate angle steel, H beam steel to worldwide for specific & urgent requirements. We have a fully advanced and modernized warehouse that stores tonnes of our value-adding A709 Gr HPS70W bridge steel plate products, which we source out from the mills that are compliant with the universal guidelines for plate production.
A709 Gr HPS70W bridge steel plate, Wear-resistant plate is one of the most widely used wear-resistant steel materials. Because of its outstanding wear-resistant characteristics, wear-resistant plate has its own unique use. First, mining machinery and equipment. During ore processing and transportation, the ore and equipment often produce violent friction, the general steel plate can not bear friction for a long time, it is easy to be damaged, and wear-resistant plate is very effective to solve this problem. Second, the ground laying. Some construction site roads are paved with wear-resistant plates, for long-term use of truck transportation.
Our stainless steel mainly is stainless steel plate/Coil. We keep 2600 tons stainless steel plate and coil A709 Gr HPS70W bridge steel plate in stock. And we refresh the our new stock every month. All the stock products from reputable mills like like TISCO, ZPSS, IISCO, LISCO, Bao steel and so on. We put all our products in Shanghai and Tianjin warehouse, which is near the loading port.
Hydrogen (H) is the most harmful element in general steel such as A709 Gr HPS70W bridge steel plate. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. A709 Gr HPS70W bridge steel plate, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate A709 Gr HPS70W bridge steel plate EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.
