		Screw processing diameter range: 25 - 200

		 

	

		Length diameter ratio: L / D = 25-28

		 

	

		Tempering hardness: HB240 °～ 280 °

		 

	

		Nitriding hardness: HV850 ° ~ 1000 °

		 

	

		Nitriding depth: 0.45-0.7mm

		 

	

		Nitriding brittleness: ≤ grade II

		 

	

		Surface roughness: Ra0.4

		 

	

		Straightness of screw: 0.015mm

		 

	

		Hard chromium plating degree of surface after nitriding: HV ≥ 900HV

		 

	

		Thickness of chromium plating layer: 0.05-0.10 mm
