S235JR S275JR S355JR SAE1006 SAE1008 black hot rolled steel sheet

S235JR, S275JR, and S355JR are European standard hot-rolled structural steel plates with increasing strength, widely used in construction and machinery manufacturing. SAE1006 and SAE1008 are American standard low carbon steel with low carbon content and good ductility, suitable for cold forming.

S235JR hot rolled steel sheet is commonly used for general structural components, while S355JR is used for load-bearing parts; SAE1006/1008 is steel commonly used for stamping parts and welding pipes, and its surface requires rust prevention treatment.

The current market has sufficient supply of S235JR and SAE1008, while S355JR steel sheet requires pre order. End users need to select materials based on mechanical properties and processing requirements, and pay attention to the chemical composition testing data in the warranty certificate.
