SS400 steel plate and Q235 steel plate
SS400 is a way of marking the Japanese steel material, equivalent to the domestic Q235 steel. Foreign standards often classify the structural steel material according to the tensile strength, such as discount price sale SS400 steel plate, SS400 which means that the tensile strength is 400Mpa minimum.
The chemical composition and physical property of SS400 steel plate:
P: below 0.050%
S: below 0.050%
Mechanical properties:
Yield strength N/mm²
More than 245 (a<16mm) above 235 (16mm<a<40mm)
More than 215 (a>40mm)
a: steel thickness
Tensile strength N/mm²
400 to 510
SS400 steel plate and Q235 steel plate
SS400 is basically equivalent to China’s Q235 (equivalent to Q235A). However, there are differences in specific indicators, Q235 has the requirement for chemical composition of C, Si, Mn, S, P, but SS400 only asked S, P’s composition less than 0.050. The yield strength of Q235 is greater than 235MPa, and the yield strength of SS400 is 245MPa. SS400 (steel for general structure) means that the general structural plate whose tensile strength is greater than 400MPa. Q235 means that the ordinary structual steel plate whose yield point is greater than 235MPa. SS400 standard number is JIS G3101. Q235 standard number is GB/T700.
SS400 is a way of marking the Japanese steel, in fact, it is equivalent to the domestic Q235 steel. Q represents the yield of this material, the latter 235, refers to the yield value of this material, at about 235MPA. With the increase of the thickness of the material, the yield value decreases. Because the carbon content is moderate, the comprehensive performance is good, the strength, the plasticity and the welding and so on are well matched. Often rolled into a wire rod or bar, Fang Gang, flat steel, angle steel, steel, steel, steel, steel frame, steel plate. Widely used in construction and engineering structures.
The utility model is used for making the steel bar or the construction of the house frame, the high-voltage transmission tower, the bridge, the vehicle, the boiler, the container, the ship, etc., and is also used as a large number of mechanical parts with high performance requirements. C, D grade steel can also be used for some professional steel.
