Q195 structure carbon steel has collected generous disquisition enthusiasm as a implicit designing material that's as of now generally applied in the development and vehicle assiduity. The material has one of a kind properties, for illustration, high malleability, strength, and welding execution, just as great wringing capacity under high pressure, yet requires face change before it tends to be consummately applied by and by. To be sure, cutting- edge revision inventions can extraordinarily ameliorate unequivocal face geologies and unpleasantness, significantly help vitality productivity, and ameliorate item prosecution and quality to construction.

Q195 Equivalent ASTM, DIN, JIS, BS, NF and ISO Standard

ASTM – Gr.B(σs185), Gr.C(σs205)

DIN – St33, S185

JIS – SS330(SS34)(σs205), SPHC(σs205), SPHD(σs205)

BS – 040A10, S185(σS185MPa).

Mechanical Properties

Yield strength: 195Mpa

Tensile strength (σb/MPa) : 315-430

Elongation (δ5/%) :

≥33 (steel thickness or diameter ≦16mm)

≧32(steel thickness or diameter>16-40mm)

Difference between Q195,Q215,Q235 and Q275

Q195, Q215, Q235, Q255 and Q275 represent the grades of steel respectively, and the grades of steel are composed of the letter (Q) representing the yield point, the value of the yield point, quality, quality and other symbols (A, B, C, D) deoxidation method symbols The four parts are composed in sequence. In terms of chemical composition, low-carbon steel grades Q195, Q215, Q235, Q255 and Q275 are larger, and the higher the carbon content and manganese content, the more stable their plasticity. In terms of mechanical properties, the above grades indicate the yield point of steel with a thickness of ≤16mm. Its tensile strength is: 315-430, 335-450, 375-500, 410-550, 490-630 (obN/mm2); its elongation is: 33, 31, 26, 24, 20 ( 0.5%). Therefore, when introducing steel products to customers, remind customers to choose steel products of different materials according to the required product materials, so as not to affect product quality.

Chemical Composition

C：≤0.12，Mn：≤0.50，Si：≤0.30，S：≤0.040，P：≤0.035

Condition

Generally delivered in hot rolling (including controlled rolling) condition. According to the requirements of the demander, upon mutual agreement, the normalizing condition can also be delivered.

Application

Used in the manufacture of anchor bolts, ploughshares, smoke pipes, roofing panels, rivets, low carbon steel wire, sheet metal, welding pipe, tie rod, hook, bracket, welding structure, etc. Rolled sheet and wire rod. Cold and hot rolled thin steel plate and galvanized, tinned and plastic composite steel plate made of the original plate are widely used in roofing board, decorative board, general dust pipe, packaging containers, iron drums, instrument shell, switch box, protective cover, train cars and so on. Wire rod is cold drawn into low carbon steel wire or galvanized low carbon steel wire, used for binding, tensioning fixed or used as wire mesh, rivets, etc.
