Q195 is a carbon structural steel. Yield strength 195MPA. Lower strength than Q235. The price is cheaper. Used in construction, structure, motorcycle frame, etc. The ASTM designation is Gr.B(σs185). σs185 means a yield strength of 185MPa.
Q235 steel plate is a steel with yield strength of about 235. It can be used for various abrasive handles and other non-essential abrasive parts.
Q235A because the material performance can not meet the pressure vessel requirements, so now Q235A has been banned from use in the manufacture of pressure vessels, which causes the market to purchase Q235A is more difficult, so now basically use Q235B to replace Q235A
Q275, is a kind of carbon structural steel, with high strength, good plasticity and cutting performance, certain welding performance, small parts can be quenched and strengthened, mostly used in the manufacture of parts requiring high strength, such as gears, shafts, sprockets, keys, bolts, nuts, agricultural machinery steel, conveyor chains and chain joints.
Q195 is a carbon structural steel with yield strength of 195MPA and advantages of high plasticity, toughness and weldability.
Q195Chemical Element Content (%)：C : ≤0.12, Mn: ≤0.50, Si : ≤0.30, S : ≤0.040, P : ≤0.035.
---------------------------------------------------------------------------------------------------
Q235：The mechanical properties of steel made of Q235B are stronger, and the mechanical properties of steel made of Q235A are weaker.In terms of welding performance, Q235B is stronger, while Q235A is weaker.
Q235A Chemical Element Content (%)：（Mn）0.30-0.65, （Si）0.3, （S）0.05, （p）0.045
Q235B Chemical Element Content (%)：（Mn）0.30-0.70,（Si）0.3, (S）0.045，（P）0.045。
