q355gnh steel hardness material quenching

We supply more than 2,000 tons of high strength q355gnh steel hardness low alloy steel coils to support the construction of Iraq's thermal power equipment projects. As a "Belt and Road" construction project, the Iraqi thermal power generation project has high requirements on the quality of steel for power generation equipment. In particular, the flue gas baffle door sealing system of q355gnh steel hardness thermal power plants has extremely strict requirements on the composition, yield strength and tensile strength of steel. Our hot rolled low alloy steel coils have won the favor of customers for their excellent mechanical properties, standard sizes, and beautiful shapes.

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

Stainless steel plate is a general term for stainless steel plate and acid-resistant steel plate, and is a steel plate with good corrosion resistance and rust resistance on the surface. The surface of q355gnh steel hardness, stainless steel plate is very smooth and clean. It has high toughness, plasticity, and is not easy to be corroded and rusted. Stainless steel plate has corrosion resistance and high temperature oxidation resistance. Stainless steel is durable, can be stored outdoors for a long time, and will not be damaged in bad weather. Stainless steel plate is not easy to rust, but it is not absolutely not rusty.

Our ogistics department has a professioanl team to support the goods’ transportation and delivery time. Its responsibilities: make customs clearance documents, track products production process, and update shipping information for customers. The company will adhere to the mission of reflecting social values, take the scientific management system as the guarantee of daily operations, and provide continuous technological innovation to support its sustainable development.

The effect of nitrogen (N) on the properties of q355gnh steel hardness and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in q355gnh steel hardness and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
