S7 Tool Steel Bar is an alloy tool steel that meets the AISI S7 specification, containing 0.45-0.55% carbon, 0.20-1.00% chromium, 3.00-3.50% molybdenum, 0.20-0.90% manganese and up to 0.35% vanadium. The steel is designed for shock‑resistant applications and achieves a hardness of 54-58 HRC after appropriate heat treatment. It is supplied in standard bar forms and is suitable for high‑impact tooling components.
In the tool‑making industry S7 is a common choice for dies, punches and shear blades because its balanced alloying provides excellent impact toughness and wear resistance. Typical heat‑treatment practice involves oil quenching followed by tempering around 540 °C, which yields the stated hardness range. Standard round‑bar sizes run from 6 mm to 200 mm diameter, while square bars are offered from 6 × 6 mm up to 200 × 200 mm, both with a tolerance of ±0.1 mm. These dimensions reflect the usual market offering for this grade.
Manufacturers of automotive, aerospace and heavy‑equipment components frequently source S7 bar for tooling that must survive repeated impacts. Buyers can request bulk quantities and the supplier packs the material on wooden pallets for secure transport. Minimum order quantities are not disclosed in the listing; interested importers should confirm the exact MOQ, lead time and Incoterms directly with the supplier.
