Temperature Effects on Metal Strength

The notes below are intended to provide general guidance to the affect of high and low operating temperatures on the strength of metals. They should only be used for initial appraisal of the suitability of metals for operating conditions away from ambient. For detailed assessment the material suppliers must be consulted. Metals are generally specified

Chemical Composition of ACI Heat Resisting Stainless Steel

ASTM standard ASTM A297, ASTM A351, ASTM A743, ASTM A744 and ASTM A890 specify castings for corrosion and heat-resisting service. The grade designations used in these standard are those originally developed by the ACI, the Alloy Casting Institute. (Now the Steel Founder's Society of America). These standards include the 'C' grades for aqueous (wet) corrosion service at temperatures

Chemical Composition of AISI and UNS Heat Resisting Stainless Steel

Most ASTM and ASME standards list the steel grades by their UNS (Unified Numbering system) numbers but also make reference, where appropriate to the more general AISI (American Iron and Steel Institute) grade designations. These grade numbering systems are widely used in the USA, where they originated and are recognised by most stainless steel specifiers and users.

Fire Resistance Rating and Testing of Stainless Steel

The inherent oxidation resistance and elevated temperature strength of stainless steel finds useful application in buildings and structures where fire resistance is very important. The most useful family of stainless steel for these applications is the austenitic, but the short-term nature of fire means that embrittlement should not be practical issue and so the ferritic and duplex families can also be considered. As materials,

Properties at Cryogenic Temperatures of Stainless Steel Tubes

The austenitic stainless steel tube remain tough and ductile to very low temperatures. Metals such as iron and constructional steel undergo a marked decrease in ductility at lower temperature. Common Cryogenic Temperatures: Environment Degrees C Degrees F Boiling Helium - 268.6 - 454 Boiling Hydrogen - 252.5 - 418 Freezing Nitrogen - 209.9 - 346 Boiling Nitrogen - 195.8 -
