BS S99 Steel
Temperature Performance
BS S99 steel retains its mechanical properties at low and elevated temperatures.
Our material is a non-corrosion resistant steel alloy containing nickel, chromium and molybdenum.
Features:
The high carbon steel alloy benefits from high strength, good ductility, creep resistance and notch toughness. Once quenched and tempered, BS S99 is ideal for engineering applications, including large cross-sections. S99 has increased molybdenum content to prevent temper brittleness. We typically stock the alloy in annealed or bright annealed solid round bars. We also provide in-house processing services, cutting bar products to specific lengths and tight tolerances.
Use in motorsport:
The alloy is used in various applications in motorsport engineering, including structural chassis parts and fasteners.
Stock Availability:
BS S99 steel bar is supplied in solid round bars in the annealed and bright annealed condition. We also provide in-house processing services where we cut your steel bars to specific lengths to suit your size requirements. All products under our care are totally traceable thanks to our unique barcoding system.
