Product Description

Q390D Carbon Steel Plate


1: Q390D Steel Introduction

    Q390D high-strength steel plate has high tensile strength and yield strength, and its hardness is also well improved after special alloying elements are added and heat treatment process. Its tensile strength is generally above 400MPa and yield strength is about 390MPa, which can withstand large pressure and bending stress, and has good fatigue resistance.Q390D high tensile steel plate has good plasticity and machinability, and it can be bent, welded, cut, drilled and other processing operations. Its excellent processing performance can reduce the processing cost and improve the production efficiency.Q390D high tensile steel plate can improve its corrosion resistance and prolong the service life by surface treatment technology, such as galvanizing and spraying. In some harsh environments, such as marine, chemical and other areas, the use of Q390D high tensile steel plate can effectively reduce corrosion and rust problems.
