Question:

What's the difference between steel plate 20 and Q235 steel plate?

What's the difference between steel plate 20 and Q235 steel plate?

Answer:

Q235 steel yield point is 235MPa, the elongation is 21-26%; widely used in the production of general machinery parts have certain strength and elongation, such as pin, shaft, rod, connecting rod, ring, bolt, nut, cylinder, gear, rack, rack and welding parts.

In the normalizing state of No. 20 steel, the yield point is 245MPa, the elongation is >25%, the quenched and tempered state, the yield point is 280MPa, and the elongation is >22%. Widely used in the production of small, high load toughness requirements of parts, such as rod, heavy and general machinery in forging the sleeve, fixture and liner, general machinery and automobiles and tractors in small parts of carburizing, cyaniding.

20 is a high-quality carbon structural steel, Q235 is carbon structural steel, and steel 20 is higher than Q235.According to the application of the situation, the two kinds of steel generally in the load is not large, the requirements are not high can be exchanged
