Customized EN 10025-6 high strength steel S690QL Z25 structural steel plate

The company operates Henan metallurgical rolling iron and steel factory all year round, providing steel products for various industries such as ow alloy high strength series, boiler and pressure vessel steel plate, power station engineering steel plate series, EN 10025-6 high strength steel S690QL Z25 bridge structure steel plate, corrosion resistant steel plate, composite steel plate, high-rise building structure, die steel plate series, steel plate series for shipbuilding and offshore platforms, pipeline steel plate, alloy structure and other steel plates.

Over the years, the company has established a standard of EN 10025-6 high strength steel S690QL Z25 steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to EN 10025-6 high strength steel S690QL Z25 quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

How to distinguish between hot rolled and cold rolled process?
The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, EN 10025-6 high strength steel S690QL Z25, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.

The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of EN 10025-6 high strength steel S690QL Z25 etc. steel material.

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.
