Steel billet size chart and weight per metre
This steel billet size chart gives the steel billet weight per metre for every section we cast. Open a size for piece weights, grades and typical forged parts:
Billet weight by size
- 100 × 100 billet weight: about 75 kg per metre, or about 900 kg for a 12 m length
- 125 × 125 billet weight: about 120 kg per metre, or about 1,440 kg for 12 m
- 160 × 160 billet weight: about 195 kg per metre, or about 2,340 kg for 12 m
- 200 × 200 bloom weight: about 310 kg per metre, or about 3,720 kg for 12 m
- 250 × 250 bloom weight: about 480 kg per metre, or about 5,760 kg for 12 m
- 200 mm round bloom weight: about 245 kg per metre, or about 2,940 kg for 12 m
Theoretical weight is side² × 0.00785 kg per metre for a square. Catalogue weights are slightly lower because of corner radius and tolerance. Use the weight calculator for other sizes or lengths, or read how to calculate billet weight.
Which size should you choose?
Small forgings usually start from 100 or 125 mm billets, medium forgings from 160 mm, and rings and heavier parts from 200 or 250 mm blooms. Read how to choose the right billet size.
Size questions
What billet and bloom sizes does Kesari Alloys supply?
100 × 100, 125 × 125 and 160 × 160 mm billets, 200 × 200 and 250 × 250 mm blooms, and 200 mm diameter round blooms, in lengths up to 12 metres. Weights per metre are on the billet size chart.
How do I calculate the weight of a steel billet?
For a square section, weight in kg per metre is side in mm squared × 0.00785. For a round section it is diameter squared × 0.006165. Use the billet weight calculator for any length. Actual weight varies with corner radius and tolerance.
What lengths are available?
Billets and blooms are supplied in lengths up to 12 metres. Shorter cut lengths are supplied on request.
