ZH70Q medium carbon high wear-resistant steel grade introduction

ZH70Q steel plate belongs to tempered type carbon rack steel, which is a high-quality steel plate created by Hesteel under special conditions. ZH70Q steel plate, Z and H are the initial letters of Zhenhua Heavy Industry, 70 means that the yield strength of the steel plate is 700Mpa, which is a high-wear-resistant carbon chromium molybdenum rack steel. ZH70Q production process
ZH70Q process requires such steel plates to have ultra-high strength, uniform and good low-temperature toughness and low crack sensitivity, yield strength of more than 700Mpa, and hardness of the tooth surface after treatment must meet the requirements. Therefore, the steel plate performance can meet the requirements to truly realize its value.

ZH70Q is mainly used for offshore wind turbine, foundation transportation and installation construction. The platform has four pile legs, which are firmly inserted into the seabed to support and fix the hull, forming a stable platform that is not affected by waves. It is a key tool for China's offshore wind power operation from shallow sea to offshore.
