band	Main features	Application examples
20CrMnTi	Carburized carbon steel can also be used as quenched and tempered steel. After quenching and low-temperature tempering, it has good comprehensive mechanical properties and low-temperature impact toughness. After carburizing, it has good wear resistance and bending strength. The heat treatment process is simple, and the hot and cold working properties are good, but there is a tendency to temper embrittlement during high-temperature tempering	"It is a widely used and widely used alloy structural steel used in manufacturing various important parts of automobiles and tractors with a cross-sectional size of less than 30 mm, such as medium or heavy load, impact resistant, and high-speed components, such as gear shafts, gear rings, gears, cross shafts, main shafts supported by sliding bearings, worms, and tooth clutches. Sometimes, it can also be used instead of 20SiMoVB and 20MnTiB"
30CrMnTi	"Mainly titanium carburized carbon steel, sometimes also used as quenched and tempered steel. After carburizing and quenching, it has good wear resistance and high static strength, and has good heat treatment process. After carburizing, it can be directly cooled and quenched, and the quenching deformation is very small. During high-temperature tempering, it has tempering brittleness."	Used for manufacturing carburized parts with extremely high core strength, such as gear shafts, gears, worms, etc., as well as quenched and tempered parts, such as driving gears with large cross sections on automobiles and tractors
20CrNi	It has high strength, high toughness, and good hardenability. After carburizing and quenching, the core has good toughness, high surface hardness, good machinability, medium plasticity during cold deformation, and poor weldability. It should be preheated to 100-150 ° C before welding, and is generally used after carburizing, quenching, and tempering	It is suitable for manufacturing heavy duty large and important carburized parts, such as spline shafts, shafts, keys, gears, and piston pins. It can also be used to manufacture quenched and tempered parts with high impact toughness
40CrNi	Medium carbon alloy quenched and tempered steel, with high strength, high toughness, and high hardenability. Under quenched and tempered conditions, it has good comprehensive mechanical properties, good low-temperature impact toughness, and a tendency to temper embrittlement. Water cooling is prone to cracks. It has good machinability, but poor weldability. It is used under quenched and tempered conditions	Used for manufacturing important quenched and tempered parts with large cross-sectional dimensions for forging and cold stamping, such as connecting rods, discs, crankshafts, gears, shafts, screws, etc

Packaging	1. by bundles, each bundle weight under 3 tons, for small outer diameter steel bars, each bundle with 4 - 8 steel strips. 2. after making by bundle, covered with Polyethylene waterproof cloth. 3. make black paints painting on each bar, then make bundles
20 feet container contains dimension	Length under 6000mm
40 feet container contains dimension	Length under 12000mm
