At present, the screw materials commonly used in China are below


Alloy structural steel: 40Cr, 38CrMoAl, high temperature alloy, etc.


1) High-quality carbon structural steel: 45#, good processing performance, but poor wear and corrosion resistance. Heat treatment: quenched and tempered HB220-270, high frequency quenching HRC45--48.


2) Alloy structural steel:


40Cr, the performance is better than 45 steel, but it is often coated with a layer of chromium to improve its corrosion resistance and wear resistance. However, the chrome plating layer is required to be high, the plating layer is too thin to be worn, and when it is too thick, it is easily peeled off. Heat treatment: quenched and tempered HB220-270, hard chrome plated HRC>55.


42CrMo, quenching and plating treatment, quenching hardness HRC48~52, hard chrome plating HRC>55, this material is easy to electroplating after quenching, the coating is firm.


38CrMoAl, nitrided steel, high wear resistance, high fatigue strength and high strength after heat treatment, excellent comprehensive performance, widely used. The nitrided layer has a depth of 0.5-0.65 mm and a nitride hardness of 1100-1200 HV. If used in combination with nickel-based tungsten carbide alloy powder, the performance is better. However, this material has a low ability to resist acid corrosion.


3) Alloy tool steel:


SKD61 (H13) quenching treatment, hardness 50 ~ 55HRC, heat treatment deformation is small. The surface can be nitrided and nitrided to make the processed product have better wear resistance; the surface is chrome-plated, and the single-layer layer is 3 wires deep, which can improve its corrosion resistance and wear resistance.


4) Stainless steel:


9Cr18MoV, 9Cr18Mo, quenching treatment, hardness: annealing is less than or equal to 269HB; after quenching and tempering is greater than or equal to 58HRC, with wear and corrosion resistance, commonly used in plastics for acidic media.


5) Other materials


The superalloy material is superior to other materials. The material is not coated. It is mainly used for the production of halogen-free screw for injection molding machine. The material has high oxidation and corrosion resistance and heat treatment HRC55~60.


Nickel alloy material C-276, used in fluoroplastic products, this material has strong acid corrosion resistance.
