Steel Standards - ASTM International

Steel Standards. The steels can be of the carbon, structural, stainless, ferritic, austenitic, and alloy types. These steel standards are helpful in guiding metallurgical laboratories and refineries, product manufacturers, and other end-users of steel and its variants in their proper processing and application procedures to ensure quality towards safe use.


Boiler efficiency— The efficiency of a boiler is the Btu’s per pound of fuel absorbed by the water and steam divided by the Btu’s per pound of fuel fired. In other words, boiler efficiency is output divided by input, or heat used divided by heat available. Boiler efficiency is expressed as a percent.

A hot water boiler, strictly speaking, is not a boiler.

The Basics of Crude Oil Classification

Class B: Considered less toxic than Class A, these oils are generally non-sticky, but instead feel waxy or oily. The warmer they get, the more likely Class B oils soak into surfaces—making them potentially hard to remove. When volatile components of Class B oils evaporate, the result can be a Class C or D residue.
