The benefits of using basic oxygen in steel production had been known as far back as the 1850s but there simply wasn't a supply of purified oxygen available. Basic oxygen steelmaking began in Austria in 1948 and resulted in spectacular increases in labor productivity in the steel industry. So what if we had started using this in 1938 instead of 1948? This would presumably eliminate the wartime steel shortages, what would the battlefield impact be?
