Q235a
Hot-rolled steel plate Q235A. Equivalent standard: JIS G3103/ JIS G3106/ ASTM A283/ EN10025/ ISO630 *Please notice that Q235A Chinese steel has exact equivalent by EuroNorms only. This is S235JR.As for other countries the closest grades are ASTM A 750 Gr. 30 and Gr.40 (USA) and SS 400 and SM 400 B (Japan). *The most closest AISI equivalent of Chinese Q235 is 1009. *The equivalents of Chinese grade Q235 in Europe are S235JR, S235JRG1, S235JRG2, S235J2G3. As for USA there are many ASTM standards which covers this grade. We consider that the closest equivalent is UNS K 02502.
Please we need to know the equivalent material ASTM Steel for Q235B.
Q235A and Q235B, the main difference lies in the carbon content, carbon content of Q235A in 0.14-0.22, Q235B carbon content in 0.12-0.20 Relatively speaking Q235B mechanical performance is far superior to Q235A steel. Which Q235B do stamping experiment, Q235A do stamping experiment. Q235A good toughness, has a certain degree of elongation, good welding and processing of. Q235A general in the hot state, the rolled steel, steel, steel plate, steel tube can be used for manufacturing various welding structures, bridges and generally not significant parts of the machine, such as bolts, rivets, pull rod, ring and the connecting rod. Q235B has a certain degree of elongation, strength, good toughness and casting of. Ease of stamping and welding, widely used in general machinery parts manufacturing. Mainly used for construction, bridge engineering quality requirements of high structure.
yield strength = 235 MPa (as implied in the name) tensile strength = 375-460 MPa See the related link for further information. Note that the main difference between different grades of Q235 (e.g. Q235A vs. Q235B) is the impact strength. Q235B has better impact properties than Q235A.
