A420 WPL8 is a ferritic low-temperature steel with a nickel content of 8.4%-9.6%. It can be used in the range of -320 ℃ to -195℃. It has the characteristics of good low temperature toughness, high strength and good welding performance. It is often used in the manufacture of various kinds of storage tanks or low temperature pipe fittings for liquefied petroleum gas, liquid nitrogen, liquid oxygen, and large-scale liquefied natural gas.
We are a manufacturer, supplier and exporter of A420 WPL8 Pipe Fittings which abide by the specifications of ASTM A420, which include wrought Carbon steel as well as Alloy Steel fittings, of seamless and welded construction. Workable under temperatures ranging from moderate to elevated, our fittings ensure better performance in the pressure piping and pressure vessel fabrication applications.
We hold a study the on market courses and requirements, to invent new, sustainable and cost-effective
products able to withstand customization. Our products are 100% durable.
