The ultrasonic flaw detection of elongation of nm500 material

Recently, a symposium on the celebration of the 70th anniversary of the founding of the People's Republic of China by the iron and steel industry was held in Beijing Convention Center. The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, BBN elongation of NM500 material Steel Staff sang songs to the mark the 70th victory anniversary. In the last of September, Henan BBN Steel organized all employees to sing ""My Country and I"" and made a film.

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

High-temperature boiler steel plates such as 15CrMoR plate, 12Cr1MoVR steel plate, ASME SA387 grade 22 steel, A387 Gr 91 boiler steel, ASME SA1017 Gr 23, SA1017 Gr 911, SA1017 Gr 122 steel, elongation of NM500 material, must have features of:Sufficient high temperature durability and durable plasticity;Good high temperature tissue stability;Good high temperature oxidation resistance (heat resistance);Good hot and cold processing technology (mainly refers to cold bending deformation and weldability), etc.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the elongation of NM500 material steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its elongation of NM500 material steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.

Alloy steel means that alloy elements are specially added to improve the properties of steel. For example, nickel can improve the strength without reducing the toughness of steel; chromium can improve the hardness, corrosion resistance and wear resistance of high carbon steel. The properties of elongation of NM500 material, alloy steel depend not only on chemical composition, but also on proper heat treatment to a greater extent.

The company is mainly engaged in elongation of NM500 material steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work elongation of NM500 material together for a better tomorrow.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
