aço de alta qualidade q450nqr1

The wear-resistant steel plate is composed of two parts: the low-carbon steel plate and the alloy wear-resistant layer. The alloy wear-resistant layer is generally 1 / 3~1 / 2 of the total thickness. When working, the matrix provides the comprehensive performance such as strength, toughness and plasticity, and the alloy wear-resistant layer provides the wear-resistance to meet the requirements of the specified working conditions.

High q450nqr1 steel is a type of weathering steel designed for use in outdoor structures. It offers good corrosion resistance due to its ability to form a protective layer of rust when exposed to atmospheric conditions, which helps prolong its lifespan. This steel is often used in applications like bridges, buildings, and outdoor sculptures.
