The Hot Rolled Carbon Steel Plate has high wear resistance and good impact performance, and can be cut, bent, welded, etc. It can be connected with other structures by means of welding, plug welding, bolt connection, etc., which is time-saving and convenient in the process of repairing the site And other characteristics, it is widely used in metallurgy, coal, cement, electric power, glass, mining, building materials, bricks and tiles and other industries. Compared with other materials, it has a high cost performance and has been favored by more and more industries and manufacturers.
Note:
1.Free Sample Available with full after-sales quality assurance and flexible payment terms are supported.
2.Customized Round carbon steel pipe can be made as your requirement (OEM & ODM) Factory Price by ROYAL GROUP.
Hot rolling is a mill process of rolling the steel at a high temperature. the temperature is above the recrystallization temperature of the steel.
Packaging is generally naked, steel wire binding, very strong.
If you have special requirements, you can use rust proof packaging, and more beautiful.
