BBN steel as a steel supplier in China,we can offer all kinds of steel stock in China,hot sell JIS G3106 Hot Rolled for Welded Structure SM570 Steel in China.
What is SM570 Steel? SM570 Steel is hot rolled steel for welded structure in the form of plates, sheets & strips for architecture, engineering structures. SM570 steel is a material grade and designation defined in JIS G3106 standard. JIS G3106 is a Japanese material standard for hot rolled steel for welded structure steel plates, sheets, strips for Architecture, Engineering Structures. The hot rolled steel for welded structure SM570 steel is more reliable in its tensile strength than SM520C steel.
Dimensional Characteristics of SM570 steel: The applicable thickness for this SM570 steel material as defined in the JIS G3106, it is from 6 mm to 300 mm.
The Chemical Composition of SM570 Steels: JIS G3106 defines the percentage of chemical composition of SM570 steel steels as under:
Maximum Carbon (C) percentage is 0.18
Maximum Manganese (Mn) percentage is 1.60
Maximum percentage of Phosphorous (P) is 0.035
Maximum percentage of Sulphur (S) is 0.035
Maximum percentage of Silicon (Si) is 0.55
Remaining is iron (Fe) percentage and with few negligible impurities.
Mechanical Properties of SM570 Steels: The tensile strength of the SM570 Steels is expressed in Newton per millimeters and it must be at-least 570 N/mm2 (MPa) and maximum can be 720 N/mm2 (MPa). The yield strength is minimum 460. The elongation property of SM570 Steel varies with the ranges of thickness. The minimum percentage range for elongation is 15.
SM520C comparison with this grade of Steel material will show how SM570 differs with SM520C in chemical composition & mechanical properties.
