JIS G3106 SM490C low alloy steel Sheet

Under Janpanese steel standard Jis g3106,SM490 has three different grades,aush as SM490A,SM490B and SM490C,the main difference is the carbon contains for these steel grades.

Comparing with SM490B,steel plate SM490C have to be done low temperature impacting test under 0 centigrade with the minimum impact energy value at 47J,SM490B with 27J for the sample test plate.

If the end users need do heat treatment for structural steel plate SM490C under Normalized,Quenched and Tempered,Tempered,they should issued this term in PO when ordered.

JIS G3106 SM490C low alloy steel sheet is a high-strength structural steel grade designed for use in welded structures that require good toughness and reliable performance. It contains a low carbon content and a controlled amount of alloying elements to ensure good weldability and formability during processing.

SM490C offers higher strength than standard carbon structural steels, making it suitable for reducing the overall weight of structural components while maintaining safety and durability.

It is commonly supplied in hot-rolled condition, providing uniform thickness, stable mechanical properties, and a smooth surface. Due to its combination of strength, toughness, and weldability, SM490C is widely used in construction, bridge building, industrial frameworks, heavy machinery, and various structural fabrication applications.
