Stil bilong Manganes (ol strongpela manganes ain)
Alloy stiel i gat moa long 10% bilong manganis. Long 1882, em i kisim namba wan manganis ain bilong austenititik oganaisesen, na long 1883, British Hadfield (R{4}}A{5}Hadfield) i kisim peten bilong hai manganese stiel{{6} Hai-manganiel stiel) i ken bruk i go long tupela lain i stap long tupela lain bilong en.

Si0.30~1.0 S 0.05 P 0.10 This kind of high manganese steel is the most used, which is commonly used to make excavator shovel teeth, rolling wall and crushing wall of cone crusher, jaw crusher fork board, ball mill liner board, railway switch, plate hammer, hammer head, etc.
Ol kast tisu bilong hai manganis stiel i save kamap long austenit, kabid na perlet, na sampela taim i gat liklik hap bilong fosforas ko-kristal. Namba bilong kabid i bikpela, planti taim i save kamap long wanpela netwok long grein bilong ol grein i save yusim na i no inap long yusim long tisyu i gat strongpela marasin bilong helpim ol manmeri i save yusim ol strongpela marasin bilong helpim ol manmeri. is solution treatment, where the steel is heated to 1050~1100℃, insulation to eliminate the cast tissue, get single-phase austenitic tissue, then water quenching, so that the tissue is maintained to room temperature. After heat treatment, the strength, plasticity and toughness of steel are greatly improved, so this heat treatment method is also often called water toughness treatment. After heat treatment, the mechanical properties are: σ b615~1275MPa σ 0.2340~470Pats ζ15%~85% ψ 15% ~ 45% wanpela Kl 96 ~ 294 J / cm2 HBl80~225
