What are the mechanical properties of steel standard ASTM A573/A573M

The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel standard ASTM A573/A573M steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.

A medium tensile, low carbon manganese steel S355JR is readily weldable and possess good impact resistance. This material is commonly supplied in the untreated or normalized condition. Structural unalloyed steel steel standard ASTM A573/A573M has a wide range of applications in construction, metallurgy, heavy and transport engineering, machine tool, power engineering and bridge building industries. Various profiles and metal structures, parts and elements of ground and underground equipment are made from steel S355JR.

EN10083-3 27MnCrB5-2 steel plates usually need quenching and tempering are special application. Up to now, EN10083-3 27MnCrB5-2 steel plates are mainly applied in airplane, guided missile, weapons, railway, bridges, ships, vehicles, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on fields.

Chromium element (Cr element) can improve the strength and hardness of steel standard ASTM A573/A573M, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

Carbon steel plates are produced with thickness up to 3mm-350mm. We can supply steel standard ASTM A573/A573M, hot rolled plate, sheets, and angles. Carbon steel plates tolerance: Thickness, width and length tolerances for steel plates are in accordance with ASTM A6. Our carbon steel plate tolerances or better are available for temper leveled plates. Flatness capabilities are determined bythe processing line and the minimum yield strength of the material.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate steel standard ASTM A573/A573M EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel steel standard ASTM A573/A573M plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
