In 1986, three unique sections specified the U.S. steel market; incorporated steel mills, mini-mills, and specialized steel makers. The integrated mills have the capacity to produce a maximum of 107 million lots of steel annually, mini-mills produced a maximum of 21 million lots of capacity a year, and the country's specialized steel makers could produce an optimum capacity of 5 million lots of stainless and specialty grades of steel. This leads to a total capability of 133 million tons of production per year. In 1986, the market taken in just 70 million lots of steel, leaving 33 million loads unused.

Nucor is at a crossroads. It deals with a saturated market experiencing considerable overcapacity. Nucor's only opportunity for development seems to be to broaden into the production of flat sheet metal. Nevertheless, to contend in that location, Nucor would need to invest in a really dangerous new technology, a thin-slab casting plant that, if successful, would enable Nucor to make flat sheet metal with a low minimum effective scale and a low limited expense of production.

This case will take a look at Nucor's history, the impacts of entering the thin-slab casting organisation, the advantages Nucor would enjoy, and whether they must develop the new thin-slab casting plant.

Taking a look at business landscape of the steel industry, it is incredible to see how well Nucor has done thinking about the market is so competitive and has fairly low success. Utilizing Porter's design, the danger of competition is high due to weak domestic demand, excess global capacity, a developing market, low changing expenses, high exit barriers, increasing operating costs (increasing raw product costs), and more than 5 similar rivals.

The threat of entry is low due to high barriers to entry (economies of scale have actually been accomplished and high capital requirements), growth and profitability are modest at best, and a lot of practical prospects are currently present in the industry and are aiming to expand into other markets. The threat of alternatives is moderate due to the fact that buyers have the alternative of picking other materials (aluminum, plastics, ceramics, etc.), and brand-new products technologies are currently being developed and looked for after.

The threat of suppliers is moderate because iron ore and scrap metal prices are currently high, energy prices are increasing, Nucor pays for transportation of its raw materials to its plants, there is no easy substitute to take the place of iron ore/scrap metal, and there is currently an overabundance of buyers of scrap metal and iron ore. Lastly, the threat of buyers is weak to moderate, because there is excess capacity, low switching costs, few high volume buyers, many low volume customers, strong demand from China, and rising feedstock prices. With the difficult business landscape in the steel industry, Nucor had to develop competitive advantages over its rivals to achieve its success. These advantages included differentiating itself by being an early adopter of computerized order tracking and allowing customers to make short time orders thus reducing their inventory. Second, it invested in modernization of its plants at an average of 2.9 times its depreciation expenses vs. an averaged of 1.6 of its competitors through the 1970s and 1980s, and refurbished on average a plant a year.

Third, Nucor strategically located its plants closer together to share orders for minimal cost and maximum sales, and building new plants in smaller rural areas with access to railroads, low energy costs, and a plentiful water source allowed Nucor to keep labor costs relatively low and made sure that COGS remained competitive. Fourth, base wages were lower but incentives were higher than average, and direct communication on expectation vs. performance provided feedback on compensation. Also, during down times, officers and CEO pay dropped dramatically while average workers did not. This led to lower employee turnover 1-5% vs. 5-10% for competitors. Fifth, Nucor’s hiring practices focused on making sure that they focused on hiring people based on potential, not experience. Finally, Nucor’s business hierarchy was different- mostly flat, resulting in less bureaucracy and more productivity per worker.

In short, many of these advantages led to Nucor becoming the second most productive steel maker per employee in the world due by 1985. Thin-slab casting was a proposed technique for mini-mills to fill orders for flat sheet steel, a segment that accounted for approximately half of the U.S. steel industry. To expand its steel market share, Nucor needed to enter the flat sheet segment. In the thin-slab casting business, Nucor would initially compete with international firms from Canada and Japan that provided high quality flat sheet steel, and cheap flat sheet steel providers in newly industrialized nations.

Barriers to entry would include large capital expenditures making new entrants cost prohibitive, but not impossible as the barrier is small comparative to the overall costs for steel manufacturing. While new rivals may not pop up immediately, new entrants from existing rivals will dilute Nucor’s competitive advantage. Nucor needed an innovative technology to be profitable in this segment as a new entrant. However, innovative technologies are risky due to development costs, unknown long-term operating costs, and the unknown quality of future products.

Also, as a first mover, increased costs will be realized. Increased maintenance above forecasts, the risk that production will not keep pace with the small-scale model, the risk that the new tech will not be fully understood by the employees and harder to run. Also, an increased likelihood that other companies will benefit from their mistakes as SMS has not made any offer to keep information gleaned from a large-scale operation confidential. However, the benefits of being a first time mover would be realized as well. The expected profit from the thin slab minimill would be $81.50 per ton, which is 26% higher than from a modernized hot rolled sheet produced in an integrated mill and 226% higher than the margin from an unmodernized integrated mill.

For cold rolled sheet, the expected profit advantage remains with minimills, with an expected profit of $107.50 per ton, which 1.9% greater than a modernized integrated mill and 115% higher than an unmodernized integrated mill. If Nucor enters the thin-slab casting business the lasting advantages may be reduced over time as others in the industry may imitate them so long as the model is proven to deliver the targeted results. If Nucor works out the kinks, then other companies will join up and the competitive advantage window will shrink, making the overall scheme too costly. If the program does not work, it is likely the other companies will not follow suit, while Nucor pays the cost for other companies “R&D” offsite. However, if the investment into the new technology proves successful, Nucor would have a significant cost savings over integrated mills initially, both in terms of entry costs and in terms of operating costs and profit margin.

This will provide Nucor with a significant competitive advantage over the integrated mills, which already provide flat-rolled steel products, but will not provide sustainable competitive advantage over the long term, as it will be easy for competitors to duplicate this technology. Many of the companies that do steel would imitate the path that Nucor is taking. They have done an excellent job of lowering cost while leveraging their competitive advantages. Furthermore, CSP is a step in the ultimate industry goal of direct casting of sheet at strip.

However, it seems as though Nucor would only gain a head start of two to three years since SMS held the CSP technology and Nucor couldn’t block others from using it. This head start doesn’t seem very advantageous as it would require almost 5 years to break (see attached chart) even and the other companies would be able to use lessons learned from Nucor’s first mover and apply it to lower their breakeven point. Overall this would be a very risky undertaking for Nucor to undertake at this time as the technology is not at an adequate tech readiness level, the initial cost to implement, as well as it could move Nucor away from its competitive advantages.
