Request a Proposal →Tensile Converter isn't just an academic exercise — it's a daily decision point across three major machining sectors. Each industry brings its own challenges, and tooling suppliers like Widia, TaeguTec, and Iscar have developed grade-specific responses.
Ti-6Al-4V and Inconel 718 dominate here. Widia grades specifically engineered for HRSA materials operate at dramatically different Tensile Converter windows than general-purpose grades. A Makino 5-axis cell machining engine mounts needs reliable Tensile Converter — there's zero tolerance for tool failure at $50K per raw forging.
High-volume production of CGI brake discs and EV motor housings pushes Tensile Converter to the limit. TaeguTec ceramic and CBN grades run at SFM levels that carbide can't touch. Cycle time is everything — a 2-second per part Tensile Converter optimization can save $180K+ annually on a 500K-unit line.
Cobalt-chrome knee implants and Ti spinal cages need pristine surface finish. Iscar's micro-grain carbide end mills, running at conservative Tensile Converter, deliver the Ra <0.4µm required. Tool change frequency is secondary to process reliability — an unexpected insert failure mid-cut means a scrapped implant.
The same Tensile Converter principle applies across all three sectors, but the optimization target shifts dramatically: aerospace prioritizes process security, automotive prioritizes speed, and medical prioritizes surface integrity. Your Widia, TaeguTec, or Iscar rep can help you tune for your specific application.
Tensile strength (ultimate tensile strength, UTS) is the maximum stress a material can withstand while being stretched before necking. Different standards use different units -- MPa (ISO), ksi (ASTM), N/mm2 (EN), kgf/mm2 (JIS).
Mild steel (1018): 440 MPa / 64 ksi. Medium carbon (1045): 565-670 MPa / 82-97 ksi. Alloy steel (4140 Q&T): 900-1100 MPa / 130-160 ksi. Tool steel (D2 hardened): up to 2000 MPa / 290 ksi. Inconel 718: 1275 MPa / 185 ksi. Titanium Grade 5: 950 MPa / 138 ksi.
Tensile strength (UTS) is the stress at which the material breaks. Yield strength is the stress at which permanent deformation begins (typically 0.2% offset). Most designs use yield strength with a safety factor. The UTS/yield ratio indicates ductility -- brittle materials have UTS close to yield.
ksi = kips per square inch. 1 kip = 1000 pounds-force. 1 ksi = 1000 psi. This is the standard unit for tensile strength in ASTM and North American specifications. Steel at 100 ksi UTS is roughly equivalent to 690 MPa.
Enter a value in any of the supported units. The converter shows equivalents in MPa, ksi, N/mm2, and kgf/mm2. Use this to compare material certificates and specifications across different standards and convert tooling catalog values to your preferred unit system.
