Low Carbon Steel Tubes 20CR4 Precision Carbon Steel Tube Astm Carbon Steel Pipe

20cr4 alloy structural steel has higher strength and hardenability, while 15Cr steel has lower toughness; It has good weldability and generally does not need heat treatment after welding. 20cr4 alloy structural steel has higher strength and hardenability, while 15Cr steel has lower toughness; It has good weldability and generally does not need heat treatment after welding. 20cr4 is used for carburized parts with high core strength requirements, large surface wear, large size, or complex shape and low load, such as gears, gear shafts, cams, piston pins, worms, etc. it can also be used as tempered parts with high working speed and medium impact load.
