Steel: Relationships

Every element and industry that Steel is linked to, and how. Each pair has its own card explaining the relationships between the two.

  • Nickel: Stainless steel takes about two-thirds of the world's nickel, so stainless output in China and Indonesia sets nickel demand, while carbon steel, most of all steel, uses almost none and its price barely tracks nickel. (researched)
  • Offshore wind: Offshore wind is built largely of heavy steel plate: monopile foundations alone take around 200 t per MW, and foundations and towers were put at about a quarter of capital cost in 2021. That makes the industry a major plate customer and exposed to steel and supply chain inflation, as the 2023 cancellations showed. (researched)
  • Transformers and power electronics: Most transformer cores are built from grain-oriented electrical steel (CRGO or GOES), a speciality grade made by few mills that is about a fifth of a transformer's cost. India imports most of what it uses, so CRGO supply and trade rules directly affect how fast it can expand its grid. (researched)
  • Vanadium: Steel is both vanadium's main customer and, in China, its main source: a few hundred grams per tonne strengthens rebar, and most Chinese vanadium is recovered from the slag of iron made from vanadium-bearing ore, so steel output drives demand and supply at once. (researched)
  • Cement: Granulated blast furnace slag from ironmaking is ground into GGBS and slag cement to replace clinker, and both materials depend on construction demand; in India, JSW Steel's slag feeds JSW Cement, the largest GGBS maker. (researched)
  • Coking coal: Blast furnace steel needs roughly 800 kg of coal per tonne, most of it as coke, so coking coal demand rises and falls with blast furnace output; India imports about 90 to 95% of its coking coal, with Australia the largest supplier. (researched)
  • Electric motors and drives: Every electric motor's magnetic core is a stack of thin non-oriented electrical steel, and the quality of that steel sets a large part of the motor's energy losses. It is a specialised grade made by few mills, so its supply and price follow their own cycle rather than the general steel market. (researched)
  • Electrical equipment: Electrical equipment needs ordinary steel for tanks, frames and transmission towers, but its critical link is grain-oriented electrical steel (CRGO) for transformer cores, which India makes in tiny volumes and imports for about 90% of its needs. (researched)
  • Graphite: Electric arc furnaces melt scrap with synthetic graphite electrodes that burn away at about 1.7 kg per tonne of steel, so electrode demand tracks EAF output rather than steel prices; India's HEG is among the world's largest electrode makers and Graphite India is another major producer. (researched)
  • Hydrochloric acid: Steel mills use hydrochloric acid to pickle hot-rolled strip before cold rolling and coating, making steel one of the main outlets for an acid that is mostly a by-product of chlorine chemistry. Large mills regenerate up to 99.5% of their acid, so merchant demand comes mainly from smaller pickling lines. (researched)
  • Iron ore: Iron ore exists almost only to make steel: a blast furnace tonne needs about 1.4 tonnes of ore, scrap-based arc furnaces need very little, and India both feeds its own mills and exports low-grade fines mostly to China. (researched)
  • Molybdenum: Steel is molybdenum's main market: about four-fifths of newly mined molybdenum (2022 data) goes into stainless, alloy and tool steels and cast iron, where it adds strength and corrosion resistance and has few good substitutes. (researched)
  • Natural gas: Natural gas can replace coke as the agent that strips oxygen from iron ore, in direct reduced iron (DRI) plants that feed electric furnaces and emit about half the CO2 of a blast furnace. About two thirds of world DRI is gas-based, but India, the largest DRI producer, makes most of its DRI from coal, and the same gas-based shaft furnaces can later switch to hydrogen. (researched)
  • Oxygen: Steelmaking is one of the largest industrial uses of oxygen: each tonne of converter steel needs about 55 to 60 cubic metres of high-purity oxygen, mostly made in air separation plants at the steelworks. Because the gas is made on site under long contracts, the tie is physical and operational rather than a traded price link, as India saw in 2021 when steel plants were called on to supply medical oxygen. (researched)
  • Vehicles, ships, rail, aircraft: Steel makes up most of a car's body and chassis and the hulls of ships and bogies of trains, so vehicle makers are among the largest buyers of flat and plate steel. The contest is now over grade and carbon: thinner high-strength steel against aluminium, and low-carbon steel at a premium. (researched)
  • Zinc: Galvanising, coating steel with zinc so the zinc corrodes first, takes about 60% of the world's zinc, so zinc demand follows output of steel that must resist corrosion, while zinc is a large share of a galvaniser's cost. (researched)
  • Construction and infrastructure: Construction and infrastructure are India's biggest steel users, about 60% of finished steel in FY26, through rebar in concrete and sections in bridges, towers and frames, so steel prices feed straight into project and housing costs. (researched)
  • Machinery and equipment: Machinery relies heavily on steel, from tractor chassis to bearings and motor laminations, and took about 16% of the world's steel in 2019, so steel prices and India's steel import duties feed straight into machinery makers' costs and margins. (researched)
  • Tin: Tinplate, thin steel coated with a few grams of tin per square metre, ties the two metals in food and drink cans: it is a sizeable use for tin but a small one for steel, and chromium-coated steel and aluminium are steadily taking its place. (researched)
