The BS970 – 1955 British Standard defines the chemical compositions and mechanical properties of steel grades widely used in engineering, manufacturing, and toolmaking. This specification ensures consistency in quality, making it a cornerstone for industries requiring high-performance steels.

Below are some of the most common steel grades covered by BS970 – 1955, with links to their detailed chemical compositions and properties:

Common Carbon & Alloy Steels

EN1A – A free-cutting mild steel ideal for machining.
EN3B – Versatile carbon steel for general fabrication.
EN8 – Medium carbon steel used for high-strength parts.
EN9 – Higher carbon steel offering superior wear resistance.
EN16 – Nickel-chromium-molybdenum alloy for toughness.
EN24 – High-tensile steel for critical applications.

Popular Stainless Steels

EN56A (304S15) – Austenitic 18/8 stainless steel (corrosion-resistant).
EN57 (316S16) – Molybdenum-enhanced for harsh environments.
EN58 (303S21) – Free-cutting stainless for machined components.

Tool Steels

EN42 – High-carbon tool steel for cutting implements.
EN44 – Chromium-vanadium steel for durable tools.

Key Applications of BS970 – 1955 Steels

These grades are trusted in:

Machinery: Gears, shafts, and bolts (e.g., EN8, EN24).
Automotive: Engine parts and structural components.
Construction: Reinforcements and heavy-duty fasteners.
Toolmaking: Drill bits, blades, and dies (e.g., EN42, EN44).
