China [CN] 1 Definition:
direct-delivery coils are cut or recoiled after end cutting, tail cutting, edge cutting as well as multi-times straightening, leveling and other finishing line treatment processes, to form hot-rolled steel plates, level hot-rolled steel coils, longitudinally-cut strips and other products.
2 Types & Applications:
1 >Structural steel
Which is mainly used for producing steel structural parts, bridges, ships and vehicles
2>Weather-resistant steel
By adding special elements (P, Cu, C, etc.), weather-resistant steel has good corrosion resistance and atmospheric corrosion resistance, and is used for producing containers and special vehicles, and also applied to structure building
3>Automobile structure steel
High-strength steel plates with good stamping performance and welding performance are used for producing automobile FRAME, WHEEL, etc.
4>Hot-rolled Special Steel
Carbon steel, alloy steel and tool steel for general mechanical structures are used for producing mechanical parts after heat treatment engineering.
5>Cold-rolled Original Plate
It is used for producing various cold-rolled products including CR, GI, color-coated plates, etc.
6>Steel Plate for Steel Pipe
It has good processability and compressive strength, and is used for producing high-pressure gas pressure vessels which have the inside volume of less than 500L and are filled with LPG, acetylene gas and various gases.
7>Steel Plate for High-pressure Vessel
It has good processability and compressive strength, and is used for producing high-pressure gas pressure vessels which have the inside volume of less than 500L and are filled with LPG, acetylene gas and various gases.
8>Stainless Steel Plate
Stainless steel has good corrosion resistance, and is mainly applied to food industry, surgical equipment, aerospace, petroleum, chemicals and other industries.

Introductions：1、Tensile test and bending test listed in the table are applicable for longitudinal test samples.
2、Tensile test adopts test samples (L0=50 mm, b=25 mm).
3、Bending test sampling schemes should be carried out in accordance with No.3 test sample of JIS Z 2204; test methods should be carried out in accordance with JIS Z 2248.
4、Hardness test is carried out in accordance with the regulations of JIS Z 2245.
5、The HRB target value is 60±8. Actual values are available in the written warranty, but are not used as acceptance requirements.
