In the following discussions, the terms "steel", "tool steel", and "carbon steel" should be understood as referring to O-1. While the physical changes and phase relationships in heat treating are substantially the same for all tool steels, the temperatures required (and other physical properties) vary widely according to composition.
AISI 1020 Carbon Steel (UNS G10200) - AZoM
IntroductionFormingHeat TreatmentCold WorkingAnnealingTemperingHardeningApplicationsCarbon steels is a category of steel, which contains 0.12 to 2% carbon. This steel category gains hardness and strength with heat treatment when the percentage of carbon content increases but the ductility is reduced. AISI 1020 carbon steel is a commonly used plain carbon steel. It has a good combination of strength and ductility and can be hardened or carburized. The following sections will discuss in detail about AISI 1020 carbon steel.How Heating Metal Affects Its Properties Metal

How to Heat Treat A36 Steel Career TrendDec 27, 2018 · A36 steel is the grade for one of the most common types of structural steels used today. A36 grade steel is considered low-alloy; however, because the carbon can range up to 0.29 percent at the most and mild steel is anything below 0.25 percent, A36 is considered the safest mild steel. As such, direct heat treating is not applicable.
q = heat required (kJ) c p = specific heat (kJ/kg K, kJ/kg C°) dt = temperature difference (K, C°) Example - Heating Carbon Steel. 2 kg of carbon steel is heated from 20 o C to 100 o C. The specific heat of carbon steel is 0.49 kJ/kgC° and the heat required can be calculated as. q = (0.49 kJ/kg o C) (2 kg) ((100 o C) - (20 o C)) = 78.4 (kJ)
Steel Tempering Colors - Engineering ToolBoxSteels containing more than 0.3% carbon are intended for heat treatment. Lower values of carbon makes the steel more tough than hard and suitable for applications where strength are important - like springs and high tensile bolts. Steels with carbon content in excess of 0.7% can be hardened to a higher degree and are suitable for applications where hardness rather than toughness is important.
The Tempering of Martensite:Part OnePlain carbon steels with less than 0.25% C are not normally quenched and tempered, but in the range 0.25-0.55 % C heat treatment is often used to upgrade mechanical properties. The usual tempering temperature is between 300 and 700°C allowing the development of tensile strengths between 1700 and 800 MPa, the toughness increasing as the tensile
If you read the preceding Instructable - An Introduction To Heat Treating Carbon Steels, then you learned that heat treating is the manipulation of a metal's molecular structure via exposure to specific temperatures. Carbon steel's molecular structure is crystalline and has a grainy appearance. Exposure to heat changes the shape of these crystals.
