The performance differences between SS400 and Q235

Shanghai Katalor could supply SS400 and Q235 steel product stock to customers, below is the performance differences between SS400 and Q235.
SS400 and Q235 are almost the same. But there are some differences in the exact performance, Q235 makes rules upon element content of C, Si, Mn, S, P and so on. But SS400 is only required the content of S, P element is under 0.05%. The yield point of Q235 is greater than 235 Mpa, while SS400's yield point is 245 Mpa. The meaning of SS400 has two parts, "SS" means SS400 is a kind of steel for general structure, and the "400" means its tensile strength is more than 400 Mpa. Q235 means its yield point is more than 235 Mpa, Q235 belongs to carbon structural steel SS400 is under standard JIS G3101, and Q235 is under standard GB/T 700.
SS400 is a steel grade symbol in Japan, in fact, it is equal to Q235. Q235 is a kind of steel material, Q represent the yield point of this material, and 235 is the numerical value of yield point, it is about 235 Mpa, and it will get smaller as the material thickness is increased. Because of SS400 steel has suitable carbon content, SS400 has better combination property, and its strength, plasticity and weldability match well, these advantages make SS400 widely used. SS400 steel is usually rolled into steel wire rod, round bar, square bar, flat bar, angle, I beam, channel, casement section steel and other section steel, medium heavy steel plate and so on. SS400 steel is widely uesd in building and construction structure. SS400 can be used in manufacturing rebar and workshop framework, high-voltage power tower, bridge, vehicle, boiler, vessel, shipping and so on, and SS400 also could be used to manufacture machine parts which have low performance. Q235C and Q235D can be used as speciality steel.
