S690QL steel plate equivalent grade astm

High strength wear-resistant plate is a kind of plate product used for large area wear condition. It is made by overlaying a certain thickness of high hardness and excellent wear-resistant layer on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. After production, the high-strength wear-resistant plate will be tested for its strength and bearing pressure. High strength wear-resistant plate is very wear-resistant, in the case of no accident, the service life of S690QL steel plate, high-strength wear-resistant plate is very long.

The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, S690QL steel plate.

Semi-endless rolling technology has three advantages: the S690QL steel plate product's limit thickness and limit width specification range has been significantly expanded. The thinnest thickness of SPHC steel has been expanded from 1.0 mm to 0.78 mm, and the limit specification product width has been expanded from 1100 mm to 1300 mm; The thinnest thickness of Q235B steel has been expanded from 1.2 mm to 1.0 mm, and the width range of the limit specification products has also been further expanded.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
