Manufacture 1 7218 Steel Widely Used In Heavy Machinery - China

1.7218 steel (equivalent to 34CrMo4/1.7220) is a medium carbon chromium-molybdenum alloy steel.

It is widely used in heavy machinery due to its high strength, good toughness and excellent hardenability.

Typical applications in heavy machinery

(1) Core components

Gears and transmission shafts: used in mining machinery (crusher gears), wind turbine main shafts, etc., to increase the tooth surface hardness (HRC 55-60) through carburizing or induction quenching.

Connecting rods and bolts: internal combustion engine connecting rods, high-strength bolts for large equipment (must meet ISO 898-1 10.9 grade standard).

Hydraulic props and track shoes: pressure-bearing parts of construction machinery (such as excavators), impact-resistant and deformation-resistant.

(2) Industry cases

Mining equipment: crusher rotor shaft, rolling mill roller (surface quenching treatment).

Energy equipment: wind turbine main shaft (requires -40°C low-temperature impact toughness).

Marine machinery: crankshafts, propeller shafts (coating protection is required for seawater corrosion resistance).

Summary: 1.7218 steel is a cost-effective choice for heavy machinery, suitable for medium to high load scenarios.

Its performance advantages can be maximized through reasonable selection, batch procurement and strict heat treatment.

If specific process parameters or supplier lists are required, further requirements details can be provided.
