£ per kg: 1 m of each size weighs its cross-section × 1 m × 7.99 g/cm³, using the density published on our 316 / 316L page. For Ø25 mm round that is π × (12.5 mm)² × 1 m × 7.99 g/cm³ = 3.922 kg.

What these numbers are. Online list prices for metal and plastic bar — round, flat, square and hex, in the sizes shown — per metre, ex VAT and excluding delivery, as shown on each stockist's own website on the date given. We read them automatically each week. History before September 2026 is Ø25 mm round bar only: it comes from dated Internet Archive snapshots of the same product pages, and an archived price is used only if that page also shows it is ex VAT. Other sizes start at their first weekly reading. Shops marked retail sell mainly to the public and are usually dearer than a stockholder for the same bar. These are not quotations, and an account or trade price will usually be lower. Each figure links to the page it was read from. A reading we couldn't take with certainty is left out, never estimated.

Why do stockists charge such different prices for the same 316 / 316L bar?

This week the dearest Ø25 mm listing is 1.9× the cheapest. Online stockists price in cutting, handling, stock-holding and the small-order market they serve, and finish and certification can differ between listings. Shops marked retail sell mainly to the public. Delivery charges differ too and aren't included here. Compare the total delivered cost for your order, not the per-metre figure alone.

What is 316 / 316L per kilogram?

1 m of Ø25 mm bar is π × (12.5 mm)² × 1 m × 7.99 g/cm³ = 3.922 kg, using the density on our 316 / 316L material page. So £37.24/m is £9.49/kg. The lowest per kg this week, across every size we track, is £9.49/kg for Ø25 mm round. Small-section retail bar costs far more per kg than mill or trade prices.
