After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, S420ML steel tube tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of S420ML steel tube steel and 542,000 tons of steel.
The company has a perfect after-sales service system and quality assurance system. The company adheres to the service principle of "all for users", and has established a professional after-sales service team. In the future service process, the after-sales service adopts regular return visit for customers. Timely understand the customer's satisfaction with our products, and solve the user's problems at any time.
S420ML steel tube, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.
Ningbo port has trade and transportation with more than 50 countries and regions, such as the United States, CIS countries, Europe, Africa, Japan and South Korea, Southeast Asia, the Middle East and Hong Kong. Ningbo port has initially formed an all-round three-dimensional collection and distribution network of expressways, railways, aviation, river sea intermodal transport, water to water transfer, etc.
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel such as toughness, plastic extension, forming, welding and cutting, abrasion, high temperature and fatigue. S420ML steel tube, Weathering steel sheets are used to manufacture containers, railway vehicles, oil derricks, harbour buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical oil equipment.
We are experienced shipbuilding and marine grade steel materials supplier and exporter with more than 20 years experience. For any question about the S420ML steel tube shipbuilding steel materials, such as shipbuilding steel price, ABS EH36 steel specification, Lloyds grade A steel properties, AH36 steel mechanical properties, AH32 steel price, DH32 steel dimensions, difference between EH36 and DH 36 etc., please feel free to consult us.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
