AISI 1045 steel<\/a>.<\/p>\nHot-rolled and cold-drawn products from this steel can be used directly without heat treatment, and also they can be used after heat treatment. The quenched and tempered medium carbon steel has good comprehensive mechanical properties. The highest hardness that can be achieved about HB 538, and the tensile strength is 600~1100MPa.<\/p>\n
Therefore, among the various uses of medium strength level, medium carbon steel is the most widely used. In addition to being used as a building material, it is also widely used in the manufacture of various mechanical parts.<\/p>\n
High Carbon Steel:<\/strong>\u00a0Carbon content:above 0.6%, is also called carbon tool steel, with a carbon content from greater than 0.60% to 1.70%, which can be hardened and tempered.Typical Grade:AISI 1060 Steel.<\/p>\nHammers, crowbars, etc. are made of steel with a carbon content of 0.75%; cutting tools such as drills, taps, and reamers are made of steel with a carbon content of 0.90% to 1.00%.<\/p>\n
The higher the carbon content, the greater the hardness and strength, but the lower the plasticity.High carbon steel is very difficult to cut, bend and weld. Once heat treated it becomes extremely hard and brittle.<\/p>\n<\/div>\n

HOW IS AISI 1020 STEEL MELTING AND REFINING?<\/strong><\/span><\/h2>\nAISI 1020 Steel is made by Electric arc furnaces(EAF) which is most commoly used in the steel mills in the world.This method converts electrical energy into heat energy, also known as electric arc furnace steelmaking.<\/p>\n
Graphite electrodes, a thermally conductive material, are used to generate electric arcs in the electric furnace by discharging between the electrodes and the charge, resulting in the conversion of electrical energy into heat in the arc. Electric arc heating melts metal and slag to smelt steels of various compositions. Electric furnace steelmaking mainly uses scrap steel as raw materials, which consumes less pig iron and no longer requires a large amount of coke.<\/p>\n
<\/p>\n
The molten steel is formulated to precise chemical compositions during the secondary refining processes.The main function of refining outside the furnace is to improve the quality of molten steel, expand the range of varieties, optimize the metallurgical production process, and improve production efficiency.<\/p>\n
The main modern refining equipment includes LF and RH refining furnaces. The main function of RH refining furnaces is to remove harmful gases and impurities in molten steel and carry out deep decarburization. LF furnaces have functions such as heating, desulfurization, and deoxidation alloying.<\/p>\n
The refined steel which is poured into various ingots or billets of different shapes and different cross-sectional dimensions is usually by die casting or continuous casting method. The solidified shapes are processed into finished goods by various processes, including hot rolling, hot forging,cold rolling, annealing.<\/p>\n<\/div>\n

IS AISI 1020 STEEL EASILY MACHINED AND FORMED?<\/strong><\/span><\/h2>\nAISI 1020 steel material is capable of being worked on via a machine. Malleability and ductility are never a question for \u00a0AISI 1020.<\/p>\n
CAN YOU EASILY WELD 1020 STEEL?<\/strong><\/span><\/h2>\nAISI ends with the number 20! It is why it has good weldability because of its low carbon content (20%). Welding and forming it to desired forms and shapes is easy.<\/p>\n
IS AISI 1020 STEEL CORROSION RESISTANT?<\/strong><\/span><\/h2>\nAISI 1020 is known as its good toughness, plasticity and weldability used as concrete reinforcement and small machine parts,but it is prone to severe corrosion,especially in hydrogen sulfide(H2S)\u00a0 conditon.<\/p>\n
IS AISI 1020 STEEL HARD ENOUGH?<\/strong><\/span><\/h2>\nAISI 1020 steel have a surface hardness below 156HBW without heat treatment,after forged or rolled.It is difficult to quench this material due to the low carbon content,but with carburizing,it can achieve hardness 30-35HRC.<\/p>\n
AISI 1018 STEEL VS AISI 1020 STEEL<\/strong><\/span><\/h2>\nThe 1018 type of steel comes from the same family of the AISI 1020 steel. The only slight difference is their percentage of carbon content. 1018 steel ends with 18, meaning it has 18% carbon, which is 2% lower than AISI 1020, having 20%.Its popularity equates with the AISI 1020 and is also one of the most purchased types of carbon steel. Hence, both are okay with heat treatments and cold-drawn situations.<\/p>\n

WHAT IS A105 STEEL ?<\/strong><\/span><\/h2>\nA105 is an American standard which belongs to ASTM A105\/A105M-2018\uff1aStandard Specification for Carbon Steel Forging for Piping Applications.<\/p>\n
The letter \u2018A\u2019 stands for\u00a0 common carbon structural steel.Since only one type of carbon steel forging is specified in this standard, A105 is also regarded as a carbon steel grade of forging. A105 is also a material code, which belongs to special steel and is a kind of cold forged steel.<\/p>\n

WHAT IS THE DIFFERENCE BETWEEN AISI 1020 STEEL AND A105 STEEL?<\/strong><\/span><\/h2>\nThe strength of AISI 1020 steel\u00a0 is slightly higher than that of 1015 steel, hardly quenched, and no temper brittleness. Cold deformation has high plasticity and is generally used for bending, rolling, flange and hammer arching.<\/p>\n
The welding performance of arc welding and contact welding is good, the thickness is small during gas welding, and cracks are prone to occur on parts with strict requirements or complex shapes.<\/p>\n
The machinability:Cold drawn or normalized condition is better than the annealed condition, and AISI 1020 steel is generally used to manufacture products with low stress and high toughness requirements.<\/p>\n
A105 is a low-carbon steel forging with mechanical properties between AISI 1020 forged steel and Q345B forged steel<\/p>\n
In the piping system, A105 steel can generally replace AISI 1020, but AISI 1020 steel cannot completely replace A105 because the difference in strength is still large. Different strength differences determine different product structures.The stress corrosion cracking (SCC) resistance of A105 is slightly worse than that of AISI 1020.We can easily have an intuitive comparison from in the below tables.<\/p>\n

This process is called aging treatment. After cold drawing, the yield point of 1020 steel is further improved, the ultimate tensile strength is also increased, and the plasticity continues to decrease. Due to the reduction of internal stress during the aging process, the elastic modulus can be basically restored.<\/p>\n Cold Drawing Schematic Diagram<\/p>\n<\/div>\n \n AISI 1020 STEEL APPLICATION-WHAT IS IT USED FOR?<\/span><\/strong><\/span><\/h2>\nIndustrial sectors largely utilize this type of steel.
