What are SPHC Steels?
SPHC steel is a hot-rolled steel that can be used in business. The JIS G 3131 standard defines SPHC
as a material grade and designation. JIS G 3131 is a standard for hot-rolled steel made in Japan.
Commercial quality hot rolled steel is a kind of steel that can be used for forming tasks, including
the sharing of a metallic sheet.
SM570 Steel is also made from hot-rolled steel, but because it is so strong, it is only used for welding. SPFH590 steel is a structural hot-rolled steel that is commonly used in the automotive industry for various applications such as chassis and other structural components. It is a high-strength steel with excellent tensile strength, and it is known for its excellent formability and weldability.
SPFH590 is a type of low carbon steel that contains various alloying elements such as manganese, silicon, phosphorus, and sulfur, among others, to achieve its desired mechanical and chemical properties.
When hot-rolled high-strength steels are used, it is possible to make parts thinner without affecting how well they work. In return, the weight savings and the whole process, from getting the materials to using the final component, can save a lot of money. Wheel hubs and rims, frames, and other auto parts are common places where this material is used.

FAQ’s About SPFH590 Steel
What is SPFH590 material?
SPFH590 steel is a high-strength, low-alloy, hot-rolled steel used mainly in the automotive industry, due to its excellent formability, weldability and high strength. SPFH590 is helpful in producing structural components, including the chassis and the body of a vehicle.
What is the full form of SPFH?
The full form of SPFH Stainless is Stomatin/Prohibitin/Flotillin/HflK ; a family of proteins in all living organisms, capable of making membrane scaffolds or compartmentalizing membranes (in cellular biology), so it can depend on the context. These letters when speaking of machinery could also mean Self-Propelled Forage Harvesters.
What is the equivalent of SPFH590 hot rolled steel?
SPFH590 (JIS G3134) is a high-strength hot-rolled steel used in automotive structures. Common equivalents in other standards include:
EN: S500MC (EN 10149-2)
USA (SAE/ASTM): SAE 490XF, or ASTM A1011 HSLAS-Class 2 Grade 550
German (DIN): QStE420TM
These equivalents offer similar mechanical properties (like strength and formability), but always verify specific chemical compositions and application requirements.
