ASTM A572 grade 50 mild steel low carbon steel plate

ASTM A572 grade 50 mild steel plate material characteristics
ASTM A572 grade 50 is a typical niobium vanadium microalloyed structural steel in the American standard. Its mechanical properties are as follows: yield strength ≥ 345MPa, tensile strength range 490-600MPa, and elongation at break 22% -35%. By combining low-carbon control (C content ≤ 0.23%) with niobium vanadium composite microalloying technology, an optimized balance between strength and welding performance can be achieved.

ASTM A572 grade 50 low carbon steel plate processing technology
We offer three delivery states: hot rolling, controlled rolling, and normalizing, with a thickness processing range of 8-300mm. Differentiated cutting solutions are recommended for different thicknesses: laser/plasma cutting is suitable for thin plates (≤ 20mm), flame cutting is suitable for medium thick plates (≥ 30mm), and non-destructive testing is required for all cutting sections.

A572 Grade 50 steel plate typical applications
Mainly used in the fields of building steel structure main beams, large-span bridge components, heavy mining equipment, and pressure vessel manufacturing, especially suitable for load-bearing structural components that require high welding reliability.

ASTM A572 grade 50 steel quality control
Strictly following the ASTM A572/A572M standard system, it can provide Z-direction performance grading (Z15/Z25/Z35) and low-temperature impact toughness guarantee (Charpy V-notch impact energy ≥ 45J at 0 ℃).
