Description of Steel 36CrNiMo4(1.6511)<\/h4>\n

36CrNiMo4 \/ 1.6511\u00a0is defined as a heat treatable and low alloy steel\u00a0which has 0.8% Cr, 0.2% Mo and 1.8% Ni as strengthening alloy elements.Compared with AISI 4140,it has higher strength and toughness,also it has very good fatigue resistance, wear resistance and atmospheric corrosion resistance.36CrNiMo4 \/ 1.6511\u00a0is generally supplied in\u00a0hardened and tempered condition with the tensile range of 930 \u2013 1080 Mpa ,hardness 280-320HB.Pre hardened and tempered 4340 can be further surface hardened by flame or induction hardening and by nitriding.<\/p>\n
