Product introduction
Screw barrel, single, double, cone double

Screw barrel material:

High-quality 38CrMoAlA; high-quality duplex stainless steel;

At present, the screw materials commonly used in our factory are 45 # steel, 40Cr, ammoniated steel, 38CrMOAl, etc.

1) No. 45 steel is cheap and has good processing performance, but poor wear resistance and corrosion resistance.

Heat treatment: quenched and tempered HB220—270, high frequency quenching HRC45--48

2) The performance of 40Cr is better than 45 steel, but it is often coated with chromium to improve its ability to resist corrosion and wear. However, the chrome plating layer has higher requirements. The coating is too thin and easy to wear, and too thick to peel off. After peeling, it will accelerate corrosion. It is currently less used.

Heat treatment: quenched and tempered HB220—270, hard chromium plated HRC > 55

3) Nitrided steel and 38CrMoAl have excellent comprehensive properties and are widely used. Generally, the nitrided layer is 0.4-0.6 mm. However, this material has low resistance to hydrogen chloride corrosion and is relatively expensive.
