What is the Q890E steel application?

GB Q890E quenched and tempered steel description

Grade Q890E

Standard: GB/T 16270-2009

Heat treatment: quenching and tempering

Quenched and tempered steel plate for high-strength structure

Q890E quenched and tempered high-strength steel has good welding performance; shot blasting before quenching, heating of the radiant tube of the quenching furnace, and non-oxidizing atmosphere control. Q890E steel has a good surface quality; special roller table design for quenching machine, partitioned water supply cooling, etc. The quality-guaranteed steel plate has uniform mechanical properties and good plate shape.

Q890E high-strength steel is suitable for the manufacture of coal mine hydraulic supports, heavy vehicles, construction machinery and other steel structures that require good welding performance, such as drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other structural parts used in mines and various engineering constructions.
