1, 30Mn steel specification: DIA 80-1200mm(forged round bar), 80-1200mm(square bar) Length 3-16 meters
2, 30Mn heat treatment: Quenching,Annealing,Normalizing and Tempering.
3, 30Mn tolerance: 0-+3mm(DIA), 0-+10mm(Length)The grade 30Mn’s strength and hardenability is higher than 30# steel. 30Mn’s weldability Plastic is medium. 30Mn has cutting good workability and cold deformation. 30Mn steel is common used in normalized condition. 30Mn steel is used in the manufacture of bolts, nuts, leverage, and small parts working under high stress.
Our company, Bebon international can produce all sizes of 30Mn forged steel stock,the best price of 30Mn steel stock,you can contact us at any time.
