API 5L X42 steel plate/pipes for large diameter pipes X42 steel plate/pipes, API 5L X42 steel plate/pipes, under API 5L standard, we can regard X42 steel plate/pipes as large diameter pipes. A709 grade 100 bridge steel plate, X42 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X42 steel used for pressure liquid transport, oil, gas, water and other liquid transportation, oilfield engineering, ductwork, construction, steel pipe and oil and gas project which use pipes.
Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. A709 grade 100 bridge steel plate, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.
Nickel element is mainly used to form and stabilize the austenite structure, so that the A709 grade 100 bridge steel plate 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.
