the characteristic of mn13
mn13 is one kind of high manganese steel without magnetic anti-impact wear-resisting. and it is suitable for high impact abrasion industry. such as abrators, road machinery, special projects, mining and metallurgy, coal, mechanical and electrical and so on.
it is the greatest impact abrasion materials.
it not only has work hardening characteristics which couldn’t be other materials instead,but also its surface can produce work hardening itself in large external shocks contact. and its hardness can increase rapidly to hb500 above,then generate high wear-resisting layer immediately.at the same time, mn13 steel internal still maintained austenitic high impact toughness.in a word,it is suitable for long time by high impact abrasion resistance materials.
mechanical properties of mn13:
yield strength: 400-500
tensile strength: 850-950
elongation: 30-50
following specifications are often have reserve: 6、7、8、10、12、15、20.
of course ,you can order specified width and length of mn13 steel.the thinnest can do 1.0 and the thick can do 2.0. and also we can help you order square steel and round steel of mn13.
