Abracorr 600

Abracorr 600

Abrasion/corrosion resistant steel

ABRACORR 600 is a fine grain weldable steel, particularly well adapted to resolve problems of severe abrasion in wet environments and in an ambient temperature of up to 600 °C. The workability of ABRACORR 600 is acceptable considering the relatively high mechanical characteristics. Typical applications are: steel plant, cement plant, sugar factories, phosphate industry, mines, public works, handling of aggregates in a salt marine environment.

General remark

If the application of this steel or the processing route have particular requirements which are not mentioned in this data sheet, please refer.

Processing information

The respect of this processing information is of fundamental importance in order to obtain complete satisfaction with the products made from this steel. The user should be assured that the calculation, construction and fabrication methods used are adapted to the material, that they correspond with the accepted rules of processing and for the desired usage.

The choice of material remains the responsability of the user.

Cutting and Welding

Due to the high level of chromium, ABRACORR 600 in an oxidising environment forms a layer of refractory oxide. This layer of oxide or calamine must be removed from the surface of the steel before the cutting operation (either mechanically or by flame without oxygen). In general preheating is not necessary before the cutting operation. ABRACORR 600 can be welded using normal procedures: a basic lowhydrogen electrode, with gas flux (MIG, MAG), with solid flux. It is recommended to use if possible electrodes with a low yield strength. In the case of extreme wear, the weld head can be protected with a final pass of chromium carbide.

Machining

In principle this steel can be drilled with HSS (High Speed Steel) tools, and it is advisable to use HSS Co (cobalt alloy) bits which give a satisfactory cutting performance if the speeds and feeds are adapted. Due to the presence of refractory oxides it is recommended to grind the area of the plate to be drilled and to mark the hole correctly so as to avoid the slipping of the bit. The use of hard steel bits is not necessary. For countersinking and sawing it is recommended to use specially hardened tools with a negative cutting angle as for hard wearing steels.

Cold forming

In spite of its high mechanical properties ABRACORR 600 can be cold formed without significant difficulty. it is recommended to grind the sheared or cut edges in the bending zone. it is also advisable to apply a slight chamfer to the edges in order to remove sharp angles in the bend zone. in any case it is not recommended to use a bending tool of less than three times the thickness of the plate.

Hot Forming and Heat Treatment

Due to the normalised condition of the steel, hot forming at a temperature of at least ≤ 925 °C can be carried out. In this case, the mechanical characteristics can be retained by leaving the work piece to cool in a calm air environment.
