Motorsport Specific Steels & Stainless Steels

AISI 4130 is a chromium-molybdenum based heat treatable steel. Its tensile strength after heat treatment is 860 N/mm2. Welded areas require heat treatment after welding to retain strength.

15CDV6 is a chromium-molybdenum-vanadium heat treatable steel with high strength after heat treatment (1080-1280 N/mm2). It is easily welded and does not require localised heat treatment after welding.

T45 is a carbon-manganese steel with a tensile strength (Rm) of 700/900 N/mm2. Fit finds many applications in the motorsport and aerospace industries due to relatively high strength to weight ratio and reduced requirement for localised heat treatment after welding.

S80 is a heat treatable chromium-nickel 431 type stainless steel in bar form. With a high chromium content of around 15% it is used in aerospace and defence components subject to high stresses up to temperatures of around 400°C.

S132 is a 3% Cr-Mo-V nitriding steel. It offers high strength and develops a hard wear resistant case after surface treatment. It is generally available in bars and forgings for use in gearbox shafts and crankshafts.

S143 is a precipitation hardening stainless steel with high mechanical strength and moderate to good corrosion resistance in a variety of media and is similar to that of basic 300 series stainless steels, with good machinability and weldability.

S98 is a 2½% nickel-chromium-molybdenum high carbon steel which is generally available in bars and forgings. Tensile strength (Rm) 1180-1420 N/mm2.

S99 is a 2½% nickel-chromium-molybdenum high carbon steel which is generally available in bars and forgings.

S145 is a precipitation hardening stainless steel with high strength and moderate to good corrosion resistance. It has an identical chemical composition as S143 and S144 but higher

S154 is a 2½% nickel-chromium-molybdenum steel generally available in bars and forgings. Tensile strength (Rm) 880-1080 N/mm2.

S155 is a Ni-Ci-Cr-Mo-V (VAR) British Standard aerospace grade, vacuum arc re-melted, through hardenable steel. It is generally used for aircraft, defence and Autosport components.

S156 is a 4% nickel-chromium-molybdenum case hardening steel which is generally available in bars and forgings. S156 is used for aircraft engineering, defence and Autosport applications. S156 is a VAR version of S82.

S157 is a nickel-chromium-molybdenum case hardening steel which is often used for applications such as gears that require high core strength and toughness. Tensile strength 1180-1380 N/mm2.

tensile strength than both, achieved through heat treatment. (Rm) 1230-1420 N/mm2.

S524 is an Austenitic chromium-nickel stainless steel stabilised with titanium. It is available in hardened/tempered sheet and strip and is suitable for medium strength components requiring good corrosion resistance and cold workability. S524 also has good weldability. Tensile strength (Rm) 800-1100 N/mm2.

S514 is a carbon-manganese steel available in sheet and strip. It is supplied heat treated to produce tensile strength (Rm) 770-100 N/mm2.
