ASTM Standards for Steel Plates for Pressure Vessels

Pressure Vessel Plates, Low Carbon Age Hardening Nickel Copper Chromium Molybdenum Columbium Alloy Steel A736 Pressure Vessel Plates, High Strength Low Alloy Steel A737 Pressure Vessel Plates, Heat Treated, Carbon Manganese Silicon Steel, for Moderate and Lower Temperature Service A738Steels 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 thorough understanding of the application and knowledge of the mechanical Low Alloy Steel an overview ScienceDirect TopicsThe conventional low alloyed steels have still been used in boiler components operated under subcritical, supercritical, and ultra supercritical pressure boiler up to the metal temperature of approximately 580°C. However, the allowable stresses are given to the temperature through to 650°C at maximum for 2.25Cr 1Mo steel, for example.

Effects of chloride transients on stress corrosion crack

The SCC growth rates of pressure vessel low alloy steel were evaluated in 288 °C water containing <5, 20, 100, and 500 ppb chloride in NWC and 5, 50, 200, and 500 ppb chloride in HWC. This research also quantitatively evaluated the impact from the delay in the growth rate response during chloride transients (memory effect).ASTM A350 LF2 (ASME SA350) Flanges for Low Temperature ASTM A350 LF2 Flange for Low Temperature ASTM A350 (ASME SA350) is the standard specification for carbon steel and low alloy steel forged flanges and flanged fittings for low temperature services.

9% Nickel Steel Ferrous & Nonferrous Alloy for Piping

The 9% nickel steel is a low carbon nickel alloy steel with nominal composition of 9Ni, which is particularly used for low temperature or cryogenic pressure vessels and plants for processing, transportation, and storage of LNG down to 196°C [ 320°F]. The steel is originated from International Nickel Companys lab in 1940s. It has relatively higher strength and allowable stress than Standard Specification for Pressure Vessel Plates, High This specification covers high strength low alloy steel plates for service in welded pressure vessels and piping components. This material is particularly intended for piping and pressure vessel applications where high strength and improved toughness are required.

The term bolting material as used in this specication covers bars, bolts, screws, studs, stud bolts, and wire.Ductilebrittle Transition TemperatureThe vessels were constructed of a steel alloy that possessed adequate toughness according to room temperature tensile tests. The brittle fractures occurred at relatively low ambient temperatures, at about 4°C (40°F), in the vicinity of the transition temperature of the alloy.
