  2. Hollow structural section - Wikipedia

    en.wikipedia.org/wiki/Hollow_structural_section

    HSS is only composed of structural steel per code. HSS is sometimes mistakenly referenced as hollow structural steel. Rectangular and square HSS are also commonly called tube steel or box section. Circular HSS are sometimes mistakenly called steel pipe, although true steel pipe is actually dimensioned and classed differently from HSS. (HSS ...

  3. Rolled homogeneous armour - Wikipedia

    en.wikipedia.org/wiki/Rolled_homogeneous_armour

    RHA is homogeneous because its structure and composition are uniform throughout its thickness. The opposite of homogeneous steel plate is cemented or face-hardened steel plate, where the face of the steel is composed differently from the substrate. The face of the steel, which starts as an RHA plate, is hardened by a heat-treatment process.

  4. Steel grades - Wikipedia

    en.wikipedia.org/wiki/Steel_grades

    Steel grades to classify various steels by their composition and physical properties have been developed by a number of standards organizations.

    SAE 304 stainless steel is the most common stainless steel. It is an alloy of iron, carbon, chromium and nickel.

  7. Steel - Wikipedia

    en.wikipedia.org/wiki/Steel

    Steel is an alloy of iron and carbon with improved strength and fracture resistance compared to other forms of iron. Because of its high tensile strength and low cost ...

  8. High-strength low-alloy steel - Wikipedia

    en.wikipedia.org/wiki/High-strength_low-alloy_steel

    High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel.HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather specific mechanical properties.

  9. High-speed steel - Wikipedia

    en.wikipedia.org/wiki/High-speed_steel

    High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is superior to high-carbon steel tools in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel.
