Quenched and tempered high strength steel 100Q-based manufacturing requirements for a good welding properties of hydraulic support to coal mining, heavy vehicles, engineering machinery, steel structure. 100Q corresponding to other brands: Q890C \ Q890D \ S890Q. 
 Wugang hardened and tempered steel composition design of low-carbon equivalent, with good weldability; steel shot blasting treatment before quenching, quenching furnace radiant tube heating, non-oxidizing atmosphere control measures to make steel with good surface quality; quenching machine for Roller design, district cooling, water supply, uniform mechanical properties of steel shelf life, and has a good shape. 
 ? Delivery Status: quenching state of delivery 
 ? mechanical properties of steel by one test and process performance 
 ? plate ultrasonic testing can be carried out by one. 
 ? 100Q physical quality of steel 
 ? I often spot on with common specifications, please be rolling! 
 ? Thank you for your interest! Provide detailed information and welding test report
