Cleveland cliffs, the largest A709 Gr 100W bridge steel plate iron ore company in North America, announced on April 13 that its Northshore mine in Minnesota and Tilden mine in Marquette County, Michigan, will suspend production based on the current market environment. The company said it would reduce inventory levels in both regions, while continuing to A709 Gr 100W bridge steel plate ship iron ore to its customers to meet commercial agreements.
When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials A709 Gr 100W bridge steel plate. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
The wear-resistant layer of A709 Gr 100W bridge steel plate wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy A709 Gr 100W bridge steel plate carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
As a leading international steel supplier, we have two warehouses, close to Tianjin port and Shanghai port. This superior geographical location effectively saves the domestic transportation cost and greatly improves our service level. At the same time, it also shortens our delivery time and provides more convenience for customers.
Will A709 Gr 100W bridge steel plate, stainless steel rust? Under normal conditions, stainless steel will not rust. It has a great relationship to the composition of stainless steel. In addition to iron, stainless steel has chromium, nickel, aluminum, silicon and so on elements. Scientists have found that the more uniform the internal structure of steel, the closer the various components are linked, and the more difficult it is for corrosive substances to invade. In addition, a layer of oxide protective film is attached to the surface of stainless steel, which is just like wearing armor on steel, it is not easy to rust.
Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products A709 Gr 100W bridge steel plate are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel A709 Gr 100W bridge steel plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
