Product Description

Cold Rolled Steel Sheet (S235J2 S235JR S275Jr S355J2 S355JR)

Product Description

Carbon steel plate for sale in our company:
1. Ingredients
The main component of carbon steel plate is iron, which contains a small amount of carbon. In order to improve its properties, some alloying elements such as silicon, manganese, phosphorus, etc. are usually added. The amount of these elements will vary depending on the use and manufacturing process.
2. Characteristics
Carbon steel plate has good mechanical properties, with high strength, hardness and good toughness. At the same time, it also has excellent thermal properties, such as maintaining high strength and hardness at high temperatures. In addition, the process performance of carbon steel plate is also good, and it is easy to carry out processing operations such as cutting, bending and polishing.
3. Uses
Carbon steel plates have a wide range of applications in many fields. For example, it can be used to manufacture parts and structural parts for industries such as ships, construction, machinery, automobiles, etc. In addition, due to its good electromagnetic properties, carbon steel plates are also widely used in the electrical and electronic industries.

Manufacturing process
The manufacturing process of carbon steel plate mainly includes the following steps
(1) Select appropriate raw materials, including iron ore, alloying elements, etc
(2) The raw materials are smelted into molten steel, and slag removal and impurity removal are carried out
(3) The molten steel is poured into the mold, cooled and formed
(4) heat treatment of the formed steel plate to improve its performance,
(5) Cutting, bending, polishing and other processing operations to meet the needs of different fields.

 

Specification
1.A36 SS400 steel is a medium tensile steel supplied in the black hot rolled or normalized condition. It has a tensile strength of 570 - 700 MPa and Brinell hardness ranging between 170 and 210.
2.AISI 1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot rolled condition.
3.A36 SS400 steel has a low through-hardening capability with only sections of size around 60 mm being recommended as  suitable for tempering and through-hardening. However, it can be efficiently flame or induction hardened in the normalized or hot rolled condition to obtain surface hardnesses in the range of Rc 54 - Rc 60 based on factors such as section size, type of set up, quenching medium used etc.
4.A36 SS400  steel lacks suitable alloying elements and hence does not respond to the nitriding process.

Machining
  A36 SS400  steel has good machinability in normalized as well as the hot rolled condition. Based on the recommendations given by the machine manufacturers, operations like tapping, milling, broaching, drilling, turning and sawing etc. Can be carried out on AISI 1045 steel using suitable feeds, tool type and speeds.

 

Welding
Certain facts about welding of A36 SS400 steel are:
· A36 SS400 steel is readily welded when correct procedure is followed.
· Welding A36 SS400 steel in through-hardened, tempered and flame or    induction hardened condition is not recommended.
· Low hydrogen electrodes are preferred for welding AISI 1045 steel.
The workpiece is
· Pre-heated at 200° C-300° C (392° F - 572° F)
· Maintained at the same temperature during welding
· Cooled slowly using sand, ashes etc and
· Stress relieved at 550° C - 660° C (1022° F - 1220° F).
