PERDUR

Perdur® steel sheets from the manufacturer Thyssenkrupp are wear-resistant steel. It has excellent usability and exceptionally high toughness.

Perdur® stands for "Performance" and "Durability", i.e. it is exceptionally wear-resistant at hardness levels of 400 and 450 HBw. A new concept that keeps carbon equivalent levels low and is appropriately aligned with the thickness range of steel plate production. To ensure the operation can be good cutting and welding.

Attribute

The steel plate is highly wear-resistant and abrasion-resistant, through water-hardening control, so it has good weld ability, and is easy to process by machining, drilling, and milling.
Hardness (HBw): Perdur400: 370-430, Perdur450: 420-480
Yield Strength N/mm² : Perdur400: 1100, Perdur450: 1200
Tensile Strength N/mm² : Perdur400: 1300, Perdur450: 1450
Permissible size and shape tolerances; For sheets cut to length according to DIN EN 10051
Sheets cut to length are controlled with maximum flatness tolerances in accordance with DIN EN 10029, Table 5 and Group H.
The surface quality requirements for cut-to-length sheets are defined in accordance with DIN EN 10163.

Application characteristics

These irons are ideal for applications where wear is carried out, such as:

Dump Truck Pickup
The agricultural machinery needs to withstand abrasion or use as a cutting edge.
Sweeper Blade
Moisten the laser cut part.
Scrap Bucket
Conveying Equipment
Sprocket
Hammer

Industries used

Cement industry
Mine
Paper
Agricultural machinery
