A283 Carbon Steel Plate

ASTM A283 is a standard specification for low and intermediate tensile strength carbon steel plates of structural quality for general application. It covers four grades (A, B, C, D) with incrementally higher minimum yield and tensile strength requirements. Q195 is a comparable Chinese standard (GB/T 700) grade, often supplied as an equivalent.

PRODUCT DETAILS

A283/Q195 Carbon Steel Plate Description

Product Overview
ASTM A283 is a standard specification for low and intermediate tensile strength carbon steel plates of structural quality for general application. It covers four grades (A, B, C, D) with incrementally higher minimum yield and tensile strength requirements. Q195 is a comparable Chinese standard (GB/T 700) grade, often supplied as an equivalent.

Key Features

Material Type: Low-carbon mild steel

Primary Characteristic: Good weldability, formability, and machinability

Common State: Typically supplied in the hot-rolled, as-rolled condition

Main Application: General structural components, building frames, platforms, truck parts, and machinery where high strength is not the primary requirement.
