Chemical composition of material api 5l x80 steel application
SM490B plate is a kind of structural steel produced according to Japanese Standard JIS G3106. Min. tensile strength of SM490B plate is 490MPa. SM490B plate is mainly used in buildings, bridges, ships, rail vehicles, oil tanks, containers and other buildings requiring high-level weldability. The delivery state is hot rolling for SM490B plate, api 5l x80 steel application with thickness less than 80mm; and the delivery state is normalizing for SM490B steel plate with thickness more than 80mm.
Advantages of api 5l x80 steel application, ordinary carbon killed steel plate: there is no gas in the steel plate, the impurity is relatively small, the stress is very uniform, and it has good welding performance. It is widely used in parts with high requirements. Disadvantages of ordinary carbon killed steel plate: the surface quality of the killed steel plate is not as good as that of boiling plates, there are concentrated shrinkage holes, and the killed steel plate price is more expensive.
Rolling steel is the process of pressing to change the shape of the ingot and billet between the rotating rolls. The so-called steel rolling process is a combination of a series of steel rolling processes. The entire rolling production process is always composed of the following api 5l x80 steel application basic processes: ① billet preparation:Including the cleaning of surface defects, the removal of surface scale and the pre-heat treatment of billets. ② billet heating ③ steel rolling: it is the core of the entire rolling production process. ④ Finishing.
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our api 5l x80 steel application products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the api 5l x80 steel application principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.Previous:api 5l x80 steel widely usage with low p Next:The stable operation of equivalent grade
