Heat resistant Q690D steel material pressure steel from BBN

Our company's Q690D steel material power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the Q690D steel material utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical Q690D steel material personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and Q690D steel material after-sales service of the project.

Q345D seamless pipe has good comprehensive mechanical properties, low temperature impact toughness, cold stamping and cutting processability, weldability. In Q345D seamless pipe, Q is the abbreviation of yield strength, 345 is the yield strength value, that is, the yield strength of Q345D seamless pipe is 345 MPa, and D is the impact temperature, which is minus 20℃. Q690D steel material, Q345D seamless pipe is widely used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, storage tanks, heavy machinery and equipment, mining machinery, power stations, plant structures, low-temperature pressure vessels, textile machinery parts, etc.

Nickel element is mainly used to form and stabilize the austenite structure, so that the Q690D steel material steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.

In 2015, we offered 230 tons 309S and 310S stainless steel Q690D steel material plate to Vietnam fabrication company. The products are used in fabricating machine for this company. Then the customer sell the machine to south America and European market. This Vietnam company purchase more than 100 ton stainless steel from us every month.
