Scrap classification & grades

Batch scrap – OW

Scrap prepared to an acceptable shape, dimension, weight and impurities so that it can be used economically and safely as a raw material in the steel melting process.

Batch scrap grades:

• OWK>3 – piece scrap with a thickness of min. 3 mm, max. dimension: 1.5 x 0.5 x 0.5 m, piece weight: max. 300 kg.
• OWK>6 – piece scrap with a thickness of min. 6 mm, max. dimension: 1.5 x 0.5 x 0.5 m, piece weight: max. 300 kg.
• OWK>10 – piece scrap with a thickness of min. 10 mm, max. dimension: 1.5 x 0.5 x 0.5 m, piece weight: max. 300 kg.
• OW5 – shredded scrap, dimension max: 0.20 m.
• OW6 – carbon steel chips in bulk, dimension max: 0.15 m.
• OWS – special scrap with a thickness of min. 8 mm and CU content<0.1%, max dimension: 1.0 x 0.5 x 0.5m.
• OWS1 – special scrap with a thickness < 8 mm and CU content<0.1%, dimension max: 1.0 x 0.5 x 0.5 m.
• OWP – scrap cut loose on the press shear, max dimension: length ≤ 0.6 m.

Non-batch scrap – ON

Scrap which requires prior manual or mechanical processing to achieve the necessary dimensions, form and mass, and the removal of metallic and non-metallic impurities, up to the limits allowed by the standard.

Non-batch scrap grades:

• ON1 – body scrap from SDP, thickness up to 3 mm,  
• ON2 – mixed demolition scrap for further processing on processing machines, thickness up to 3 mm,
• ON3 – scrap in the form of clean sheet metal (e.g. domestic appliance casings, panel radiators), thickness up to 3 mm,
• OND – scrap in the form of loose wires, without ropes and strings, thickness ≥ 3mm
• ONK3 – scrap to be processed on a pressing shear (in the form of e.g. sections, profiles, tubes, etc.), thickness ≥ 3mm
• ONK6 – scrap to be processed on a pressing shear (in the form of e.g. sections, profiles, etc.), thickness ≥ 6mm
• ONK10 – scrap to be processed on a pressing shear (in the form of e.g. sections, profiles, etc.), thickness ≥ 10mm
• ONP – scrap to be processed using a gas torch (in the form of e.g. shafts, rails, machine parts, etc.)
