How to protect the EN10025-4 steel S460M from cracking

The company is a large EN10025-4 steel S460M steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the EN10025-4 steel S460M enterprise, and make our own contribution to the development of the world economy.

As a leading EN10025-4 steel S460M, S420NL hot rolled plates and sheets supplier, we can supply structural steel S420NL plates up to 250mm. It is often delivered in normalized or normalized rolled condition. When customers need doing the third party inspection for S420NL steel plates,our mill would issue the MTC under format EN10204 3.2, the third party can stamped and report the result on our original MTC when inspection is done completely.

Q245R boiler steel plate introduction: Q is the first letter of "Qu" Chinese Pinyin; Number 245 is the yield strength value; R: is the first character of "Rong" Chinese Pinyin. Q245R steel is a special plate for pressure vessels and boilers with a yield strength of 245MPa. It has outstanding mechanical properties and processability. If you have special requirements, our company can supply Z15, Z25, Z35 and other Z performance tests.

Oxygen (O) is a harmful element in steel such as EN10025-4 steel S460M. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.
