Introduction

Q370R technical parameters / mechanical properties
The delivery state is normalized, -20 degrees, impact can also be controlled or rolled out of the steel plate according to the requirements of the manufacturer or design
Fire treatment.
Q370R belongs to the domestic brand, is a boiler and pressure vessel plate, steel plate is in the GB713-2014 standard issued after the emergence of a brand. The old standard is 15MnNbR
Delivery status: Inspection
Wuyang steel plate to the container plate by default is three levels of crack detection, according to special requirements, can be customized two and a level, other steel factory does not default to contain three level flaw detection, if necessary, must be specified, mainly used for making pressure vessel
