Oct 07, 2004From what I have seen, the FATT (@50% flat fracture) for low carbon steels can range from 20 deg F down to -20 deg F. To be conservative in design, I would recommend 20 deg F due to variability in material composition and grain size.(plate) What is low carbon steel?What is low carbon steel?Low carbon, 3.5%-nickel steels are often used in liquid gas storage tanks at temperatures down to -100°C. Many aluminium, nickel, and titanium alloys are also suitable for these temperatures. Aluminium 7076-T6 can also be used up to -128 °C, but not for critical applications.Metals and materials for low temperatures and cryogenic Minimum temperature range for common low carbon steels
Jun 28, 2012Normalizing - AISI 1018 mild/low carbon steel should be heated at 890°C 940°C and then cooled in still air. Forging - This process requires heating at 1150°C - 1280°C and AISI 1018 mild/low carbon steel is held until the temperature becomes constant. 900°C is the minimum temperature required for the forging process.(plate) Austenitization Temperature - an overview ScienceDirect Minimum temperature range for common low carbon steels (steel) The recommended standard austenitizing temperatures for annealing or normalizing these grades are similar respectively 885 and 915 °C for 1015, and 845 and 900 °C for 1045 (13) but do show that the 1015 composition requires higher temperatures for austenitizing.
Mar 06, 2016If this steel is now cooled from the 700 deg C temperature to room temperature, the microstructure does not change significantly, no matter how slow or fast the steel is cooled. The ferrite remains a nearly pure bcc iron with less than 0.02 % C dissolved in it, and the cementite remains at 6.7 % C with an unchanged crystal structure.(plate) Fundamentals of the Heat Treating of Steel(steel) carbon steel and low-alloy steel, the maximum carbon is about 2.0%; in high-alloy steel, about 2.5%. The dividing line between low-alloy and high-alloy steels is generally regarded as being at about 5% metallic al-loying elements (Ref 1). Fundamentally, all steels are mixtures, or more properly, alloys of iron and carbon.(plate) How To Above Microscopic view of Ferrite (top), Austinite (bottom left), Pearlite (bottom right)When Above Microscopic view of Austinite (top) and Cementite (bottom)Cooling very slowly from the Heat treating is all about changing the molecular structure of a steel in order to improve its working Above (Top) Steel Temperature Color Chart (Bottom) Iron / Carbon Phase DiagramLike all facets
Our low-temperature carbon steel pipes have been developed chiefly for use in low-temperature. They are low- to medium-carbon (0.20 to 0.30%), high-manganese (0.70 to 1.60%), silicon (0.15 to 0.60%) steels, which have a fine-grain structure with uniform carbide dispersion.(plate) Low Temperature Carbon Steel Pipe vs. Carbon Steel Pipe Minimum temperature range for common low carbon steels (steel) Jun 15, 2017If the low temperature carbon steel piping is seamless, it can be installed when processing or manufacture piping requires low temperatures to avoid negative impact on this type of piping. One example of use of low temperature carbon steel pipe would be in processes where refrigerants are required to be 50° F.(plate) Managing Cold Temperature and Brittle Fracture Hazards in Minimum temperature range for common low carbon steels (steel) Jan 04, 2016The design temperature of vessels prior to 1987 allowed the use of carbon steels and alloy steels to 29 °C (20 °F) without the need of impact testing. If less than 29 °C (20 °F), impact testing was required.
Most low carbon (0.20-0.35%) martensitic steels can be used with sufficient reliability. Many of these alloys contain manganese, nickel, chromium, molybdenum and vanadium, and some zirconium and boron. Materials suitable down to -100 °C Low carbon, 3.5%-nickel steels are often used in liquid gas storage tanks at temperatures down to -100°C.(plate) Minimum Design Metal Temperature (MDMT) and Impact (steel) Jul 13, 2020The use of a material at a design minimum temperature colder than 29°C (20°F) is established by para. 323.2.2 and other impact test requirements. For carbon steels with a letter designation in the Minimum Temperature column, the curve in Figure 323.2.2A of ASME B 31.3 (Reproduced in Fig. 2) is used. MDMT depends on the nominal thickness.(plate) Normalizing Carbon Steels 5 Steps - Instructables(steel) There, it states that the low end of the transformation range of carbon steels is 1333°F. The color chart also states that steel glows somewhere between dull red and cherry red at 1300°F. So, getting the steel up to a temperature that makes it glow bright red or into the orange range, tells us that we are in the austenetic range.
When the base metal temperature is below 32°F [0°C], the base metal shall be preheated to a minimum of 70°F [20°C] and the minimum interpass temperature shall be maintained during welding.(plate) Service Temperatures of Austenitic Steels - Penflex(steel) Most austenitic steels, with chromium contents of at least 18%, can be used at temperatures up to 1500°F and Grade 310 (Cr content up to 26%) even higher up to 2000°F.(plate) Steel properties at low and high temperatures(steel) Figure 2. Effect of low temperatures on the mechanical properties of steel in plain and notched conditions. Surface grinding with grit coarser than 180 and shot-blasting causes embrittlement at -100°C due to surface work-hardening, which, however, is corrected by annealing at 650-700°C for 1 h.
Other alloy steels are suitable for service in the low-temperature range. The steels A201 and T-1 can suffice to -45°C, nickel steels with 2.25% Ni can suffice to -59°C, and nickel steels with 3.5% Ni to -101°C.

For low-stress applications, plain carbon steels can be used at temperatures ~25 °C (800 °F). Temperatures up to about 540 °C (1 000 °F) can be withstood for only short periods.
