Kanish Metals is a reliable maker and supplier of Tool and Die Steel S7 bars in Dubai, UAE, providing high-quality steel bars designed for resistance to impact and durability in heavy-duty industrial applications. Renowned for their outstanding toughness and shock resistance, S7 steel bars are extensively employed in tooling and die sectors where high-impact strength is paramount. Kanish Metals guarantees each batch of S7 steel bars conforms to international quality standards of mechanical properties and dimensional accuracy. Operating in auto, aerospace, and heavy machinery industries, Kanish Metals provides consistent quality S7 steel bars with guaranteed delivery and first-rate customer service.
Tool and Die Steel S7 bars are produced using an air-hardening, shock-resistant alloy steel with approximately 0.5% carbon, 1.3% chromium, and other minor constituents such as molybdenum and vanadium. This composition offers good toughness, high impact strength, and wear resistance. S7 steel is heat-treatable to obtain hardness of up to 58 HRC while still possessing excellent shock absorption properties. It has good dimensional stability when heat-treated and provides excellent resistance to chipping and cracking when subjected to high impact or shock loads.
