Meaning and Definition
A type of tool steel alloy that retains its hardness and cutting ability at high temperatures, used primarily for making cutting tools.
Any alloy steel designed for use in high-speed machining operations, characterized by high red-hardness (the ability to retain hardness at high temperatures) due to significant tungsten, molybdenum, chromium, vanadium, and cobalt content.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Spelling conventions follow standard BrE/AmE patterns for component words (e.g., 'high-speed' is hyphenated identically).
Connotations
Identical technical connotations in both varieties.
Frequency
Equally low frequency in general discourse but standard within metalworking, engineering, and manufacturing contexts in both regions.

FAQ
Frequently Asked Questions
No. High-speed steel is a specific alloy for cutting tools that retains hardness at high temperatures. Stainless steel is primarily alloyed for corrosion resistance and is generally not suitable for high-speed cutting tools.
Yes, it is commonly abbreviated as 'HSS' in technical catalogs, engineering drawings, and industry jargon.
Its primary application is in cutting and machining tools (drills, taps, saw blades). Rare secondary uses might include high-wear components in extreme environments, but other materials are usually preferred for non-cutting applications.
Its key advantage is 'red-hardness' or 'hot hardness' – the ability to retain a significant portion of its room-temperature hardness even when heated to dull red temperatures (around 600°C/1112°F) during high-speed machining.
High-speed steel is usually technical/industrial in register.
High-speed steel: in British English it is pronounced /ˌhaɪ spiːd ˈstiːl/, and in American English it is pronounced /ˌhaɪ spiːd ˈstiːl/. Tap the audio buttons above to hear it.
