Here are some key factors to compare when choosing 4120 and 4142 tool steels:<\/p>\n\n\n\n
Chemical composition:<\/h5>\n\n\n\n – 4120 steel contains carbon (C: 0.18-0.23%), silicon (Si: 0.15-0.35%), manganese (Mn: 0.90-1.20%), chromium (Cr: 0.40-0.60%) and molybdenum (Mo: 0.13-0.20%).<\/p>\n\n\n\n
– 4142 steel contains carbon (C: 0.40-0.45%), silicon (Si: 0.15-0.35%), manganese (Mn: 0.75-1.10%), chromium (Cr: 0.8-1.1%) and molybdenum (Mo: 0.15-0.25%).<\/p>\n\n\n\n
Mechanical properties:<\/h5>\n\n\n\n – 4120 steel has a tensile strength of \u2265885 MPa, a yield strength of \u2265685 MPa, and an elongation of \u226512%.<\/p>\n\n\n\n
– 4142 steel has a tensile strength of more than 1700 MPa, a yield strength of more than 650 MPa, and an elongation of more than 35%.<\/p>\n\n\n\n
Heat treatment:<\/h5>\n\n\n\n – 4120 steel is usually used in the quenched and tempered or carburized quenched state.<\/p>\n\n\n\n
– 4142 steel can be heat treated to achieve a good strength level while maintaining reasonable toughness.<\/p>\n\n\n\n
Application areas:<\/h5>\n\n\n\n – 4120 steel is suitable for manufacturing high-pressure pipes and various fasteners, higher-grade carburized parts such as gears, shafts, etc. in non-corrosive media and working temperatures below 250\u00b0C.<\/p>\n\n\n\n
– 4142 steel is suitable for brake molds, bending molds, support tools, mold bases, gears, flanges, chucks, mandrels, spindles, axles, clutch parts, forming rollers, wrenches and other hand tools due to its high strength, high toughness and good wear resistance.<\/p>\n\n\n\n
5 Corrosion resistance:<\/h5>\n\n\n\n – 4120 steel has good weldability and machinability, but its corrosion resistance is not as good as 4142 steel.<\/p>\n\n\n\n
– 4142 steel has better corrosion resistance due to its higher content of chromium.<\/p>\n\n\n\n
Price:<\/h5>\n\n\n\n –<\/strong> Depending on market conditions, the prices of 4120 and 4142 steel may vary. Generally, 4142 steel may be slightly more expensive due to its higher strength and corrosion resistance.<\/p>\n\n\n\nConclusion<\/h2>\n\n\n\n Taking the above factors into consideration, 4142 steel may be a better choice if high strength and corrosion resistance are required. If the budget is limited and weldability and machinability are high requirements, 4120 steel may be more suitable.<\/p>\n\n\n\n
