Jul 03, 2006 · A36 at high temperature My company is considering using ASTM A36 plate for in an application where temperatures between 1000 - 1100 F are normal (engine exhaust). Our competitors, we are told, use "carbon steel" so we are looking into the issue. The unit, (36" round x 24" lg, 12 ga) does not see any load other than an internal pressure of about ASTM A36 Mild Steel - SAE AISI 1010 1015 1020 1025 1045 ASTM A36 Standard Specification for Carbon Structural Steel covers carbon structural steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of bridges and buildings, and for general structural purposes. Heat analysis shall be used to determine the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, and copper.
Low Temperature Steel Pipe Calculations. As stated in a previous post on cold temperature and equipment, low temperatures have an undesirable affect on ductile steels, making them more brittle and prone to failure.This is a problem in process piping, especially in Canada, with a large range of temperatures in the summer and winter seasons. Metal Stock, Inc. - Hot Rolled ASTM A36 Info.ASTM A36 has a machinability rating of 72%, based on 1212 at 100%. Average surface cutting feed is 120 ft/min. ASTM A36 is easily welded by all welding processes, and the welds and joints produced are of extremely high quality. HEAT TREATING - Forging, Normalizing, and Annealing: Pressure Temperature Rating and Flange rating of ASME The terms like Flange Pressure Temperature Rating, Flange Rating, P-T rating, Flange Pressure rating, Pressure rating or Flange Class, etc. are frequently used in Piping Engineering. This article will briefly explain such terms with respect to ASME B 16.5 and ASME B 16.47.
S, M, and HP shapes and channels, A36 or A572 Gr. 50 should still be specified. For angles and plates, A36 should still be speci-fied (for more information, see the three-part series, Are You Properly Specifying Materials, which appeared in the Jan.-March issues of MSC). The major advantage of A992 is its better mater-ial definition. Steels for Cryogenic and Low-Temperature Service ::Total Carbon and alloy grades for low-temperature service are required to provide the high strength, ductility, and toughness in vehicles, vessels, and structures that must serve at 45°C and lower. Because a number of steels are engineered specifically for service at low temperature (about 100°C), selecting the optimum material calls for T Class Ratings Temperature Ratings Hazardous Area T T Class Ratings Hazardous Areas. Temperature Classifications are given to hazardous area Temperature Class Ratings (also known as T-ratings or T-Class) and are applied to hazardous area zones and electrical equipment T Class Ratings are utilised for all hazardous areas and explosion protection methods.. This helps the user to quantify the level of thermal energy allowed in the
Temperature Rating for Common Tubing Materials. NOTE:The pressure rating of a tube is negatively affected by maximum operating temperature and severity of service. Temperature Derating Factor table and Severity of Service Derating Factors table are included below. Temperature Rating for Common Tubing MaterialsTemperature Rating for Common Tubing Materials.

Temperature and A36 Structural Steel - CR4 Discussion Oct 17, 2006 · Re:Temperature and A36 Structural Steel 10/17/2006 8:30 PM -20 F is certainly low enough to promote brittle fracture if carbon content is high, as was the case with the Liberty ships which saw service in the north Atlantic.
Apr 16, 2009 · 2) For stainless steel specs there is a range of -120 to 350 deg C (-184 to 662 deg F) for 304L. Other specs I have seen have temperature ranges of -103 to 302 deg F with 304L, and -50 to 300 deg F with 316L. I could not find anything in B31.3 that would suggest how these temperature ranges were originally selectedASTM A36 Steel Properties, Modulus of Elasticity, Yield ASTM A36 Steel. ASTM A36 steel is one of the most widely used carbon structural steels, although the carbon content of A36 material is maximum 0.29%, it is considered to be the mild steel (content of carbon 0.25%).. A36 mild steel is often compared to AISI 1018, A36 carbon steel is commonly hot rolled, while 1018 steel is commonly cold rolled.. Notes:There are two versions that define low
