Q195 Q235 Wire Rod
Q195 wire rods and Q235 steel wire rods are carbon structural steel coils.
Q195 and Q235 are both grades of carbon structural steel, which represent different yield strength grades.Q195 has a yield strength of 195 MPa, while Q235 has a yield strength of 235 MPa.These two types of steel are used in a wide variety of applications due to their moderate carbon content and good overall properties, including strength, plasticity, and weldability.
-
Raw materialpreparationIncluding the preparation of iron water, to ensure that the content of sulfur, phosphorus and other harmful elements in iron water is controlled within the specified range to ensure the quality of steel. -
Smelting Continuous CastingBy smelting in a converter, the chemical composition, such as the content of carbon, silicon, manganese, phosphorus and sulphur, is controlled to meet the standard requirements of Q195 and Q235. Continuous casting of the smelted steel into billets, this step is the basis for the production of coils. -
RollingThe billet after continuous casting is rolled, and it is rolled into the specified size and shape by rolling mill. -
FinishingCarry out finishing treatment for the rolled coils, including heat treatment and surface treatment, in order to achieve the required mechanical properties and appearance quality.
Finished product processing
The quality steel wire rod after finishing is inspected, packaged and other treatments to ensure that the product quality meets the standard requirements.

WIRE ROD Q195 Q235
Mechanical properties: Q235 steel yield strength and tensile strength is higher, can withstand a certain amount of pressure and impact, which makes the Q235 wire rod is not easy to damage in the construction process, can maintain its structural stability. In contrast, Q195 steel has lower tensile strength and lower elongation, and its mechanical properties are relatively weak. Therefore, Q235 wire rods are more suitable in scenarios where they need to withstand greater pressure and impact.
Machinability: Q235 steel has good machinability and weldability, which facilitates a variety of processing in the manufacturing process, including bending and welding. At the same time, Q235 wire rods also have better sealing and integrity at the joints, which can effectively ensure the stability and reliability of the coil. The processing performance of Q195 steel is relatively poor, and its weldability and processability are not as good as Q235 steel, so it needs to be more careful in the manufacturing process.
Corrosion resistance: Although Q235 steel is not stainless steel, its corrosion resistance can be effectively improved and the service life of the coil can be extended through certain surface treatment and anti-corrosion measures, such as galvanisation and painting. In contrast, Q195 steel has poor corrosion resistance and is susceptible to rust and corrosion due to environmental factors. Therefore, Q235 steel wire rods are more suitable in scenarios that require long-term use.
Cost Effectiveness: The relatively lower cost of Q195 steel compared to Q235 steel helps to reduce the overall production cost of the coil. However, Q235 steel wire rods are more cost-effective in the long term when considering aspects such as coil longevity and performance stability. Therefore, when choosing a coil material, both cost and performance considerations need to be taken into account.
APPLICATIONS
Q195 hot rolled steel wire is mainly used in the manufacture of ground bolts, ploughshares, smoke pipes, roofing panels, rivets, mild steel wires, sheet metal, welded pipes, tie rods, hooks, brackets, welded structures, and so on.
Q235 mild steel wire, on the other hand, are generally used for construction purposes, including, but not limited to, building structures, bridges, house frames, etc. Q235 has higher yield and tensile strengths, and is able to withstand a certain amount of pressure and impact, which makes it more suitable for scenarios where it is required to withstand greater pressure and impact.
