\n4130 steel example in round bar shape\/form<\/p>\n
To help you understand this particular steel more, here\u2019s a quick breakdown of the chemical content of the 4130 steel.<\/p>\n
\nThe strength, ductility, and overall toughness of 4130 steel is due to its chemical composition<\/p>\n
NOTE:\u00a0<\/b><\/strong>This is based off of the standard of the ASTM; also, as per specified by the AISI and the SAE:<\/p>\n This is the regular chemical composition of the 4130 steel. But have you ever wondered why it\u2019s called and deemed 4130 steel in the first place?<\/p>\n In case you\u2019re not aware, the term \u201c4130\u201d is because of its composition. The first (1st<\/sup>) digit of the grade refers to the steel class and the alloying parts. The second (2nd<\/sup>) digit is the symbol for the alloying elements\u2019 relative percentages.<\/p>\n The last digits (3rd<\/sup>\u00a0and 4th<\/sup>) is the representation of the carbon content in it \u2013 it\u2019s shown in increments of 0.01%.<\/p>\n That being said, it\u2019s easy to say that the 4130 steel is a part of the 41xx family (which is chromium-molybdenum steels with 1%, and about 0.30% of carbon.<\/p>\n 4130 weighs approximately 14lbs\/ft or .25 lbs per inch of thickness. This means the 4130 steel tubing with a diameter of one inch will weigh about six pounds while 4130 sheet metal with a thickness of one eighth of an inch will weigh about 0.06 lbs per square foot.<\/p>\n The 4130 steel tubing has a diameter range from .188\u2033 to nearly 13\u2033. 4130 sheet metal is available in thicknesses ranging from less than 60 thousandths (0.060\u201d) up to and exceeding two inches. 4130 tubing and 4130 sheet metal are available with an inside radius as small as one-half inch on tube sizes up through two inches in diameter.<\/p>\n 4130 steel is stronger than 4150 or 4340. 4130 also has a higher fatigue limit, meaning it can withstand more stress over time before breaking. However, 4130 is lighter in weight than 4150 or 4340. This makes 4130 a good choice for applications where a high strength to weight ratio is important.<\/p>\n No, 4130 steel is not magnetic. 4130 has a low carbon content and the addition of chromium and molybdenum helps to prevent the formation of magnetite. This makes 4130 less susceptible to corrosion and improves the hardness of the steel. 4130 is not magnetic which makes it ideal for welding and forming without creating any harmful effects to the steel.<\/p>\n 4130 has a black oxide finish that can be easily painted or powder coated over top of to protect against corrosion, oxidation or rusting after fabrication into parts. 4130 sheet metal has a dull finish with a slight sheen. 4130 tubing has a shiny finish and can be easily welded without causing any damage to the steel.<\/p>\n Yes, 4130 is heat treated using the quench and temper process. After the steel has been formed into its desired shape, it is heated to a high temperature and then quickly quenched in oil or water. This causes the steel to harden and temper, which gives it its strength and toughness. 4130 is typically tempered at a lower temperature than 4150 or 4340 to avoid any loss of toughness.<\/p>\n The chemical composition of 4130 is as follows:<\/p>\n Carbon 0.28-0.33%<\/p>\n Manganese 0.70-0.85%<\/p>\n Phosphorus 0.035 max<\/p>\n Sulfur 0.040 max<\/p>\n Chromium 0.80-0.90%<\/p>\n Molybdenum 0.15-0.25%<\/p>\n Silicon 0.15 max 4130 steel has a carbon content of .28-.33%, manganese of 0.70-0.85%, phosphorus at 0.035%. 4130 also contains chromium and molybdenum, which are both used in the quench and temper process to provide 4130 with its strength and toughness. 4130 does not contain sulfur, but 4150 contains 0.15%.<\/p>\n 4130 steel has a minimum yield or tensile strength at 55 KSI (80,000 PSI). This means that if you were to pull on two 4130 steel pieces with a force of 55,000 pounds per square inch (PSI) they would break. 4130 is much stronger than 4150 or 4340 but it also weighs more as well making 4130 best for applications that require high strength and low weight.<\/p>\n Yes, 4130 has excellent corrosion resistance and can be easily painted or powder coated after fabrication. 4130 is corrosion resistant compared to 4150 which contains sulfur, making 4150 more susceptible to rusting as well as other forms of oxidation such as heat checking, pitting and crevice corrosion.<\/p>\n Yes! 4130 steel is an excellent material for projects. 4130 steel has great corrosion resistance and is easily welded, machined or formed without causing damage to the steel. 4130 does not contain sulfur like 4150 which makes 4130 less susceptible to rusting after fabrication into parts. Because 4130 weighs more than 4150 it is best used in applications that require a high strength to weight ratio. 4130 is also stronger than 4150 or 4340, making it a good choice for projects that need a high level of strength.<\/p>\n Some common applications for 4130 steel include tubing, sheet metal, structural shapes and automotive parts. 4130 can be easily welded, machined or formed without
