1. The Economic Explanation of Technical Change:The case of Nucors Entry into US Strip July 2003 Jonathan Aylen
Centre for Manufacture
University of Manchester Institute of Science and Technology
2. Nucors Entry into Strip Nucors entry into strip production
Entry as a game
Why didnt big steel oppose the entry ?
North American imitators
European developments in thin slab casting and direct rolling
Lessons from this case study
3. Nucors Innovations Process innovation worlds first commercial thin slab direct strip rolling plant in 1989
Business innovation flat business organisation based on incentives
4. Republic Steel open hearth melting shop, Cleveland, Ohio Nucor versus Big Steel Big steel slow to innovate:
Slow to adopt oxygen steelmaking
Slow to adopt conventional continuous casting
5. Nucors Entry to US Strip Market Nucor used process innovation to enter strip market:
New technology
New business systems
6. Cost Advantage Strategy Standard product low price/cost margin
No sales promotion or price complications
Capacity fully utilised and matched to demand
Search for cost reducing innovation
Strong emphasis on pay based on productivity
No overheads, administration: tight cost control
7. Why didnt Big Steel Oppose Nucors entry ? Big Steel committed to existing thick slab concast technology to make quality products:
Bethlehem, USX, Inland, Armco, Weirton, National, Rouge, Wheeling-Pittsburgh
8. Nucors Entrepreneurship Firm Specific Issues
Nucor keen to grow strip their chance
Suffered new entry into their own markets of rod and bar
Joint venture with Yamato in sections
Experience of new plants in steel and engineering (e.g. bolt manufacture)
Developed new business model
9. Shouldnt incumbents adopt first ? Established firms less incentive to innovate as it cannibalises existing profit get profits from existing plant first (Kenneth Arrow)
versus
Rivals will steal the business, so pre-empt them get there first ! (Fudenberg & Tirole)
10. Big Steel versus Entrant Is the innovation revolutionary or modest ?
What sort of post-adoption competition?
Price or output competition ?
Will the technology succeed anyway?
11. Big Steel versus Entrant Thin slab casting:
Likely to have major impact
Likely to reinforce price competition
Likely to succeed
So why did Big Steel let it happen ?
12. Incumbent v. entrantthin slab production Fairly certain process, uncertainty was Nucors lack of familiarity with process;
Strong engineering support from SMS keen to make it work;
Many established components;
Commercial scale pilot plant for continuous casting.
13. SMS thin slab pilot plant in their foundry Schloemann-Siemag a reliable partner Leading strip and continuous casting equipment supplier
Extensive pilot testing
Would not have chosen Nucor as a partner !
14. Incumbent v. entrantthin slab production On all counts, theory suggests the incumbent should aggressively adopt the new technology to prevent business stealing
Why didnt this happen ?
15. Thin-slab casting rolling of strip Seen as non-threatening innovation
Coordinate prices in Big Steel
Quality problems of thin strip an inferior technology
Scale matters Nucor small scale
Nucor just more efficient
Puppy-dog ploy small, remote plant less provocation
16. Cost of Cold Rolled Coil Nucor versus Big Steel 1995
17. Nucor built Chinese Copies Nucor, Hickman, 1992
Nucor, Berkeley, 1996
18. Nucor spawned Imitators Ten thin/medi slab plants in North America threatening big steel followed Crawfordsville
Developments Worldwide
European (and Mexican)Technical Advances:
Ultra-thin strip
Semi-endless rolling
Ferritic strip
19. Nucors Imitators not all successful ! Trico joint venture:
British Steel
Sumitomo
LTV
Went for higher quality
Shut 2001
Sold to Nucor 2002
Innovation is risky !
20. North American Imitators
21. Nucor: lessons for innovation Inferior technologies often challenge the existing, conventional trajectory of development
Inferior technologies are usually improved and applied more widely if they offer key advantages (e.g. cost savings)
The technology paradigm changes infrequently, but sometimes dramatically
22. Corus IJmuiden under construction Generation V the second stage of innovation KruppThyssenStahl & Corus IJmuiden
BOS fed
Semi-endless rolling
Ferritic rolling potential
Carousel coilers
23. Generation V emerges Motivation:
Low cost route to range of strip products
Pre-empt other entrants to European strip production - learn from Nucor in USA
Challenge USINOR in strip they bought Arvedi as part of Arcelor merger
Extra capacity to supplement conventional thick slab mills at Thyssen, Krupp and Hoogovens
So, innovation a strategic move by established firms
24. KruppThyssen, Bruckhausen and Corus IJmuiden quality enhancements BOS feed, not arc higher quality input
Ladle steelmaking (temperature, calcium)
Sophisticated continuous casters submerged entry tundish/reduced mould turbulence
Ultra-long tunnel furnaces for semi-endless rolling
High pressure descalers for surface quality
High power seven stand mills
25. Higher slab quality than the pioneers electro magnetic braking Crucial to reduce mould turbulence
But,
Works better on narrower slabs
Expensive, only justified in a quality market
However,
Familiar pattern, inferior technologies improve
26. KruppThyssen and Corus IJmuiden Corus IJmuiden:
Transition to ferritic rolling (difficult)
Carrousel coilers
Short run-out table
Thickness planned down to 0.7 mm
Low carbon, HSLA and ferritic grades
27. Ipsco, Mobile, Alabama The Innovation spreads: New Generation Compact Plate Mills use thin slab continuous casting Compete with imports in USA
Corus, coil plate
Tuscaloosa
IPSCO
Montpelier, Iowa
Mobile, Alabama
Nucor
Hertford
28. New Generation Plate Mills Embody lessons of thin slab for strip low cost route to low quality product
Wide, thin slab casters
Markets in construction, bridges, barges, rail cars, storage tanks, agricultural machinery, pipework
Often combination plate/Steckel mills making both discrete and coil plate
Discrete plate rolled to 3 metres wide (120)
Plate thickness 5 mm to 50 mm
29. Ipsco Mobile, first slab Wide, thin plate slab casters
30. Implications of this case study for Technical Change Innovation can be a strategic move to out-flank competitors
Inferior technologies may win out (and improve over time, e.g. EMBr on concast moulds);
Established firms learn from newcomers;
New technologies migrate across sectors;
New technologies may destroy existing firms long after they first appeared
