HSLA Grade 50

High-Strength Low-Alloy. Higher strength-to-weight ratio than carbon steel. Used in automotive and structural applications where weight reduction is key.

Reference properties

• Category: Steel
• Density: 0.284 lb/in³
• Yield strength: 50,000 psi
• Tensile strength: 65,000 psi

Available tempers and conditions

Grade 50 — 75-90 HRB

Min 50ksi yield.

The condition on the purchase order changes forming behavior as much as the alloy does. HSLA Grade 50 is stocked in a single listed condition; confirm which one the certification covers before committing die clearance, bend radius, or press tonnage.

Production use

As a steel product, HSLA Grade 50 should be compared against other grades in the same family before substituting — density drives coil and part weight, while the yield and tensile basis above drive forming load and springback.

Published families and nominal properties vary by grade, temper, thickness, processing history, and governing specification. Confirm the actual purchase specification and material certification before releasing a die, forming process, weld procedure, or production setup. Surface condition, grain direction, coating, work hardening, edge quality, and lot-to-lot variation can affect performance even when nominal strength values match.

Verification checklist

Verify units, thickness tolerance, yield and tensile basis, and any temperature or direction dependence. Run a representative trial when forming limits, safety, or high production volume make an incorrect assumption costly. This page is a reference, not a material certification or supplier guarantee.

Estimate cost with the material cost calculator, check coil and blank weight with the sheet weight calculator, or return to the production material library.
