Hyundai Steel Co. has no plans to cut production further despite weak steel demand due to the coronavirus pandemic, the company's president said. Earlier this year, South Korea's second largest steelmaker reduced its A633Gr.D physical properties annual production of hot rolled coils from 1 million tons previously to 700 thousand tons per year for EAFs. A turnaround is expected after the third quarter of this year. In the three months to March 31, Hyundai Steel had a net loss of 88.6 billion won ( million), up from 94.4 trillion won in net profit in the same period last year.

The company's sales department has a professional team, they have professional steel knowledge, respond quickly, with the problems raised by customers can quickly give solutions, put the interests of customers first. With their own professional knowledge to provide customers with high-quality steel plate in line with the requirements. At the same time, in terms of price, we also have great advantages. Members of the business department make sure that the delivery time is short and the service is the best.

Heat treatment advantages of A633Gr.D physical properties, SA516 Gr 70 pressure vessel steel:
1) SA516 Gr 70 pressure vessel steel quenching: The hardness of SA516 Gr 70 pressure vessel steel is increased, but the toughness is decreased.
2) SA516 Gr 70 pressure vessel steel normalizing: Improve strength and toughness.
3) SA516 Gr 70 pressure vessel steel annealing: Eliminate quenching effect, eliminate stress, uniform composition.
4) SA516 Gr 70 pressure vessel steel tempering: Uniform composition, slightly reduce hardness, greatly improve toughness.

The company uses outsourced logistics operations. Our cooperated professional third-party logistics providers use the advantages of large-scale production and cost advantages to achieve cost savings by increasing the utilization of resources in each link, so that we can benefit from the separation of cost structure. Therefore, we can also provide customers with better, faster and more efficient cargo transportation, delivery, and lower freight costs.

A small amount of Nb is sufficient to obtain excellent comprehensive properties of A633Gr.D physical properties etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products A633Gr.D physical properties are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
