  2. 4340 steel - Wikipedia

    en.wikipedia.org/wiki/4340_steel

    Contents. 4340 steel. 4340 steel is an ultra-high strength steel classified a medium-carbon, low-alloy steel. 4340 steel has high strength, ductility, toughness, creep resistance, and fatigue resistance relative to most other steels. Hardness ranging from 24 to 53 HRC can be achieved, depending on the heat treatment.

  3. Ramsbottom carbon residue - Wikipedia

    en.wikipedia.org/wiki/Ramsbottom_Carbon_Residue

    The carbon residue of a fuel. The Ramsbottom test is used to measure carbon residues of an oil. In brief, the carbon residue of a fuel is the tendency to form carbon deposits under high temperature conditions in an inert atmosphere. This is an important value for the crude oil refinery, and usually one of the measurements in a crude oil assay.

  4. Micro carbon residue - Wikipedia

    en.wikipedia.org/wiki/Micro_Carbon_Residue

    Micro carbon residue, commonly known as "MCR" is a laboratory test used to determine the amount of carbonaceous residue formed after evaporation and pyrolysis of petroleum materials under certain conditions. The test is used to provide some indication of a material's coke -forming tendencies. [1][2][3] The test results are equivalent to the ...

One US gallon (3.79 litres) of gas in an F-style can A group of 25 kg (55 lb) liquefied petroleum gas (LPG) cylinders in Malta. A fuel container is a container such as a steel can, bottle, drum, etc. for transporting, storing, and dispensing various fuels.

  6. Equivalent carbon content - Wikipedia

    en.wikipedia.org/wiki/Equivalent_carbon_content

    The carbon equivalent is a measure of the tendency of the weld to form martensite on cooling and to suffer brittle fracture. When the carbon equivalent is between 0.40 and 0.60 weld preheat may be necessary. When the carbon equivalent is above 0.60, preheat is necessary, postheat may be necessary. The following carbon equivalent formula is used ...

  7. Stress corrosion cracking - Wikipedia

    en.wikipedia.org/wiki/Stress_corrosion_cracking

    Stress corrosion cracking (SCC) is the growth of crack formation in a corrosive environment. It can lead to unexpected and sudden failure of normally ductile metal alloys subjected to a tensile stress, especially at elevated temperature. SCC is highly chemically specific in that certain alloys are likely to undergo SCC only when exposed to a ...

  8. Container compression test - Wikipedia

    en.wikipedia.org/wiki/Container_compression_test

    Compression test for steel drum. The container compression test measures the compressive strength of packages such as boxes, drums, and cans. It usually provides a plot of deformation vs compressive force. It is commonly used to evaluate shipping containers made of corrugated fiberboard as well as wooden boxes and crates.

  9. Carbon steel - Wikipedia

    en.wikipedia.org/wiki/Carbon_steel

    Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states: no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium, zirconium, or any other element to be added ...
