Description

457 451 varigenom det blir möjligt att spara avsevärt mer energi än vid fast upplösningsbehandling enligt tidigare känd teknik, och trots detta framställa överlägsna produkter.
Enligt uppfinningen anvisas' ett förfarande för fram- ställning av austenitisk rostfri stålplåt, innehållande upp till 0,08 vikt% kol, upp till l,0 vikt% kisel, upp till 2,0 vikt% man~ gan, 8,0-l6,0 vikt% nickel, l6,0-20,0 vikt% krom, 0- 30 vikt% mo- lybden, upp till 0,25 vikt% kväve och resten järn och eventuella föroreningar, kännetecknat av att ett råämne av rostfritt stål valsas vid en temperatur över TR = 940 + 30 (%Mb)°C, varefter det valsade râämnet kyles från en temperatur över 800°C till en temperatur under SOOOC med en kylningshastighet som är högre än Rc (OC/sek), vilken framgår av föjande ekvationer: log (Rc) = 0,32 + 14 (æc + sn) - o,os7 (evo) när
