Product Description

Product Description

The plunger is a key component in a plunger type hydraulic cylinder that enables linear motion and thrust output. It is typically a solid circular rod with a surface that has been precision ground to reduce friction coefficient. The material commonly used is high-strength and high hardness alloy steel such as chromium alloy to improve wear resistance and compression resistance. To reduce weight and minimize bending deformation, the plunger can also be made hollow.

Application

Hydraulic press machine,such as:
cold chamber die casting machine,etc.

Production Procedure

Forging, Rough machining, Heat treatment:normalizing+quenching+tempering, Final processing

Feature

1.Choose alloy steel forging material ,42CrMo,etc.
2.Its material has high strength, high hardness, and high wear resistance.
3.Through heat treatment quenching and tempering.
4.Surface treatment : 2Cr13-4Cr13 stainless steel overlay welding , layer thickness 4mm.
5.Carry out 100% UT/MT inspection before shipment.

2Cr13-4Cr13 Chemical Composition

2Cr13-4Cr13 is a martensitic stainless steel with certain corrosion resistance, strength, and wear resistance. It is commonly used to manufacture components such as blades, pump valves, bearings, etc. that can withstand moderate loads and require slight corrosion resistance.
