Product Introduction

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.

Scope of Application

ASTM A283 steel plate is a kind of low carbon steel with high strength and good formability. It is easy to process and manufacture, and can be safely welded by various welding methods. ASTM A283 steel plate is a structural carbon steel plate used for low or medium tensile strength applications. ASTM A283 steel plate is used in the manufacture of riveted, bolted and welded structures for storage tanks and cryogenic control vessels, bridges and buildings, including prefabricated buildings, warehouses and industrial commercial structures.

Packing and shipping

Our company has passed ISO9001 quality management system certification, Our Mill product with CE/EN10204 / ASTM/Classification society certificate/CASO/BIS etc certificate.All the customers give good appreciation to our products.We are glad to be your good partner.

Application Areas

Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments. ‌
