Q195 is a carbon structural steel with a yield strength of 195MPA.
Chinese name Q195 attribute carbon structural steel yield strength 195MPA application construction, structure, motorcycle frame, etc. C (carbon)≤0.12Mn(manganese)≤0.50Si(silicon)≤0.30S(sulfur)≤0.040P(phosphorus)≤ 0.035 Deoxidation method F, b, Z tensile strength 315-430 (σb/MPa) advantages High plasticity, toughness and welding performance
Q195 carbon steel pipe is a carbon structural steel. The yield strength is 195MPA. Lower strength than q235 carbon steel pipe. Used in construction, structure, motorcycle frame, etc. The American ASTM brand is Gr.B (σs185). σs185 is the yield strength of 185MPa.

| Short Description | Spiral welded pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another. The two sides of the double submerged arc weld penetrate the full thickness of the steel to ensure the strength of the finished pipe. Full scale tests have shown that high quality spiral welded pipe is as strong as API pipe. The strength and flexible manufacturing of spiral welded pipe make it the product of choice for a variety of applications. |
