Carbon Steel Plate Supply by Grade, Standard & Application

Carbon Steel Plate Overview

A carbon steel plate is a flat steel product where mechanical properties are primarily controlled by carbon content, rolling process, and heat treatment condition. Compared with alloy steel, carbon steel plates offer stable performance, good weldability, and wide standard acceptance across global markets.

Typical application fields include:

• Structural steel fabrication and load-bearing components
• Pressure vessels, boilers, and storage tanks
• Industrial equipment, machinery bases, and welded assemblies

Depending on the grade, carbon steel plates can be supplied in hot-rolled, normalized, or controlled rolling conditions.

Carbon Steel Plate Grades & Standards

Carbon steel plate grades are specified according to application, strength requirement, and governing standard. Commonly supplied standards include ASTM, EN, and GB.

Estándar	Grado	Aplicación típica	Límite elástico	Key Difference / Selection Tip	Details Link
ASTM	A36	General structural steel	≥250 MPa	Widely used for beams/columns; good weldability	View A36 Details
ASTM	A516 Gr.60 / Gr.70	Boiler and pressure vessel plates	220–260 MPa (by grade)	PVQ quality, Gr.70 offers higher tensile strength; impact test requirements should be specified	View A516 Details
ASTM	A572 Gr.50	High-strength structural	≥345 MPa	High yield strength; suitable for bridges & heavy structures	View A572 Details
ES	S235JR	General construction steel	≥235 MPa	European standard; moderate strength	View S235JR Details
ES	S355	High-strength structural	≥355 MPa	Higher yield than S235; weldable	View S355 Details
GB	Q235	Acero estructural	≥235 MPa	Common Chinese standard; general use	View Q235 Details
GB	Q355	High-strength structural	≥355 MPa	Stronger alternative to Q235; heavy structures	View Q355 Details

This carbon steel plate grades chart is provided as a general reference. It summarizes commonly used carbon steel plate grades across major international standards. Final chemical composition and mechanical properties are confirmed by mill test certificates in accordance with the applicable standard.
