St50-2 Material HSLA Plate

Basic Information

Type: High-Strength Low-Alloy (HSLA) Steel Plate

Standard: Based on German DIN standards (e.g., DIN 17100, obsolete but still referenced), St50-2 is part of the "St" series for structural steels.Designation Breakdown:

St: Abbreviation for "Stahl" (German for "steel").

50: Indicates a nominal tensile strength level (approximately 500 MPa, though exact values vary by thickness and standard).

2: Typically denotes a quality grade or processing condition (e.g., normalized or thermomechanically rolled for improved mechanical properties).

Key Properties

Mechanical Properties

Tensile Strength: ~500–630 MPa (depending on thickness and manufacturing process).

Yield Strength: ≥345 MPa (for thinner sections; decreases with increased thickness).

Elongation: ≥18–22% (good ductility for formability).

Impact Resistance: Moderate toughness at ambient temperatures (may require testing for specific applications).

Technical Advantages

High Strength-to-Weight Ratio: Reduces material thickness and weight in structures without compromising load-bearing capacity.

Good Weldability: Low carbon content and balanced alloying ensure minimal risk of heat-affected zone (HAZ) brittleness.

Formability: Suitable for bending, stamping, and other cold-forming processes due to adequate ductility.

Corrosion Resistance: Better atmospheric corrosion resistance than plain carbon steel, thanks to alloying elements like Cu (in some grades).

Alloy Composition (Typical)

Low Alloy Content (total ≤3%):

Carbon (C): ~0.15–0.25% (keeps carbon equivalent low for weldability).

Manganese (Mn): ~1.0–1.6% (enhances strength and hardenability).

Silicon (Si): ~0.15–0.50% (improves deoxidation and strength).

Microalloying Elements (optional): May include small amounts of V, Nb, or Ti for grain refinement and strength enhancement.
