German Standard W Nr 1 7218 Steel Export Large Inventory - China

W-Nr.

1.7218 steel is a German standard structural steel and a type of alloy structural steel.

The following is a detailed introduction to this material from many aspects: Basic information

Weighting method: Weighing by weighing.

Specifications: The specifications are relatively complete, including Φ260 - 270, Φ55 - 100, Φ100 - 105, Φ151 - 180, Φ170 - 190, Φ260 - 280, etc.

Chemical composition and properties

Chemical composition: Phosphorus (P) content ≤ 0.035.

Mechanical properties: W-Nr.

1.7218 steel has high strength and toughness, high hardenability, and a critical hardenability diameter of 15 to 70 mm in oil; the thermal strength of the steel is also good, with sufficient high temperature strength below 500°C, but its strength drops significantly at 550°C.

Machinability

When the alloying elements of W-Nr.

1.7218 steel are at the lower limit, the weldability is quite good, but when it is close to the upper limit, the weldability is moderate, and it needs to be preheated to above 175℃ before welding; W-Nr.

1.7218 steel has good machinability and moderate plasticity during cold deformation.
