3.2.1.2 Carbon steel. Carbon steel is used in vacuum technology, as long as pressures of less than about 1 · 10 5 hPa do not need to be created and maintained and corrosion protection is not required. Compared to stainless steel it is a relatively low priced building and construction material, which has good weldability and is easy to process. However the continuous outgassing of CO and the tendency Stainless Steel For Vacuum Applications Vacuum Services LtdStainless steel grades most commonly used for vacuum applications are austenitic stainless steels such as 304, 304L, 304LN 316, 316L and 316LN. Stainless steel grade 304L has a low carbon content to 304 and is the most commonly selected grade in the manufacture of vacuum vessels, vacuum flanges, vacuum fittings and internal vacuum components, this is due to their excellent properties for: .Standard Specification for Quenched and Tempered Vacuum 1.1 This specification 2 covers quenched and tempered vacuum treated carbon and alloy steel forgings for pressure vessels such as those used in reactor systems. Specifically, it covers forgings for vessel closures, shells, flanges, tube sheets, rings, heads, and similar parts. 1.2 All grades are considered weldable under proper conditions.

Mar 28, 2012· High and ultrahigh vacuum vessels often undergo bake out procedures at temperatures of 200°C or 400°C. At 200°C the vapor pressure of zinc is approximately 5 x 10 6 Torr while that of cadmium is 3 x 10 4 Torr. At 400°C these rise to roughly 0.1 Torr and 1 Torr respectively. Small carbon steel fasteners are frequently cadmium plated.6 Best Materials Ideal for Pressure Vessel Applications The vacuum vessel manufactured by BEPeterson for our 60" system was among the largest we've incorporated into a line. We'd not worked with BEPeterson before JB Filtration had searched the New England States for a modern, efficient, high quality steel fabricator for Material Requirements for Carbon Steel Pressure VesselsNote 1Vessels 24" O.D. and smaller may utilize SA 106, Grade B seamless pipe for the shell.. Note 2Vessels 24" O.D. and smaller may utilize SA 234 Grade WPB pipe caps in lieu of forged elliptical heads.. Note 3For ANSI Class 150 and 300 flanges, SA 181 Class 60 material may be utilized in lieu of SA 105 if the latter is not available.. Note 4All SA 515 and SA 516 components should be

For example, for 304L grade stainless steel plate, ASME II Part D provides two rows of stress properties to identify SA 240 304L stainless steel in

Steel Standards ASTM International

ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.6 Best Materials Ideal for Pressure Vessel Applications The vacuum vessel manufactured by BEPeterson for our 60" system was among the largest we've incorporated into a line. We'd not worked with BEPeterson before JB Filtration had searched the New England States for a modern, efficient, high quality steel fabricator for ASTM A508 / A508M 18 Standard Specification for 1.1 This specification 2 covers quenched and tempered vacuum treated carbon and alloy steel forgings for pressure vessels such as those used in reactor systems. Specifically, it covers forgings for vessel closures, shells, flanges, tube sheets, rings, heads, and similar parts.

Most vacuum vessels in the heat treating industry are cylindrical in shape and either horizontal or vertical in orientation (Fig. Nos. 2 3). In general, vacuum vessel designs are made as small as possible so long as they dont hamper the process being run in the vessel.
