16MnD5 is a medium carbon quenched and tempered steel with good strength, toughness and hardenability. It can obtain better comprehensive mechanical properties after quenching and tempering. After quality, it has higher fatigue strength and resistance to multiple impacts. Low temperature impact toughness Good, no obvious temper brittleness. A709 grade 50W high strength steel product is mainly used to make evaporators, voltage stabilizers, pressure vessels and heads, supporting members, etc. in nuclear power projects
We will return our customers with zealous service attitude, high quality products and favorable price. We have been accumulating, perfecting, developing and expanding constantly. We have huge A709 grade 50W high strength steel steel products stock. We have won the trust and support of our customers with high-quality service and excellent product quality. The company adheres to the development concept of honesty and win-win cooperation. We are willing to form an alliance with like-minded partners to work together for development and common progress.
A709 grade 50W high strength steel annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of A709 grade 50W high strength steel annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. A709 grade 50W high strength steel annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
When the steel plate containing molybdenum only is at high temperature for a long time, the carbon will aggregate into graphite and precipitate, which will worsen the performance. To eliminate this tendency, chromium is often added to the A709 grade 50W high strength steel, steel plate at the same time. When chromium is added to the steel plate, the heat strength, high temperature oxidation resistance and corrosion resistance can also be improved.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
